Rear axle swap out for disc brake upgrade + 5 lug conversion

[Neinris]

Aloha YW! I hope everyone is being healthy and staying safe. I'm sure I'm not the only one that can't wait to put behind this pandemic that's crippling the world. In the mean time, I'm staying at home unless absolutely necessary to go out.

While at home, I get to sit down more to think and surf the internet. I've revisited some of the old threads here, and also some more recent ones, taking your ideas as to what I can do my Dee Dee.

I'm almost done with all the exterior mods that I want to do, just looking for side skirts that are decently priced, and waiting for the weather here in SOCAL to get warmer, so I can color match the added bodykit and spoiler. I'm having a dilemma picking which wheels to get, the title should give you an idea why.

After addressing the exterior mods, I obviously want to tackle the performance portion next. I'm aiming to do an engine swap, then handling upgrades, like brakes, sway bars, then suspension in that order I think. Or I might just keep my current suspension set up. I'm on Tein's lowering springs right now, the first thing I did to Dee Dee, and already I felt a significant change in her handling, lower center of gravity and less body roll. And I like how the ride is still comfortable. I'm not going to track her much, if at all, so I don't feel the need for a full coilover upgrade. What do you guys think? Anyone out there using TEIN Street Advance Z Adjustable Coilovers? How's your ride comfort?

So like I said, I've been doing a lot of thinking, and revisiting of the threads. There's old thread about five lug conversion, and there's threads about rear disc conversion upgrade. Well, I was coming out of a grocery store on Saturday, and a Scion xB was parked next to me. Not the old boxy ones, but the more newer model with five lugged wheels. Anyway, I just realized how huge the rear rotors are! According to AutoZone, they're 279mm in diameter! The front are 275mm. That's a hell of an upgrade if I could ever get them to fit my Dee Dee. Soooo... I was wondering if the Scion xBs rear axle would fit our car? And for the front, would the xBs front wheel hub spine fit the Yaris' or xDs, or whatever that can be substituted to mate to our transmission. I guess I have some researching to do.
So this is where my dilemma lies, choosing between 4 lug wheels or 5 lug wheels? LOL! The wheels I have in mind are 16X8 ET 25, wrapped in 195/50. I've seen some 4X100 in that configuration, not sure about 5X114.3 though.
I guess it can wait for now, cause right now all this plan is just in my mind. Who knows when I'll get to the next step of the plan.
My apologies if I'm just rambling, I just thought I wanted to share.
Be safe everyone, and stay healthy.

Not sure about the rear xb rotors but the yaris and xD's front bearing and hub are interchangeable. ie, theres nothing stopping you from using the 5 lug equipment on the yaris driveshaft. So if you wanted the 5 lug xD front hubs, press out the 4 lug yaris ones and press in the 5 lug xD hubs. Warning: the bearing will probably be garbage after removing the hub.

rear disc brakes are expensive and overkill unless youre going to be doing a lot of racing/lapping.

good front pads and just about any kind of rotor will be good for a DD

I'm just brainstorming right now really and just putting out what's on my mind. Your conversion is what gave me the idea about maybe swapping the xB axle instead of a the 3rd GEN Yaris SE for the rear disc conversion. And at the same time give ideas to those who wanted to do a 5 lug conversion. The 5 lug pattern for the xD is 5X100, the 5 lugged xB are 5X114.5 which have better wheels selection.
Your right, the bearings will be trash after swapping the hubs. I messed up when I did a 5 lug conversion on my 92 Prelude, I didn't support the inner racer when I was pressing in the hub, not knowing that they come in halves. As I was pressing it in, the bottom half came apart but not fall out, I pressed it in the other way hoping that it'd be fine. I few weeks later I had to replace that bearing even though it was brand new.

I don't know about rear disc brakes being overkill and expensive. Wouldn't disc brakes (pads) last longer than drums(shoes)? Wouldn't you get a better bang for your buck? OK, maybe 179mm rotors for the rear and 175mm for the front on a Yaris would be overkill... LOL!!!

But, replacing pads are easier than replacing shoes for me.

I too have thought about doing a rear brake conversion as well as upgrade the front brakes. That said, I don't track or autocross my car and have found the stock brakes to be fine. I will be purchasing Hawk pads and a decent quality set of blank rotors fairly soon. I have also been speaking to another modified Yaris owner and he directed me to the RunStop products out of Thailand, I believe. They have an oversized front rotor (285 mm vs stock 255 mm) and different caliper bracket. I will probably just do the Hawk pads and stock-sized quality rotor. However, I will be watching this build with great enthusiasm if you go forth with it, Neinris. I hope you do.

WOW! You'll watch me?!! I'm flattered. I'm the one who's been following your thread here and Toyotanation, and watched all your YouTube videos I think so far. You've done really, really well with your Yaris. I've left a reply in the MCM Yaris video I said to turbo it and linked them your build, this was right after they had just installed the 2ZR-FE.

If the aim is to just improve the braking performance, then I believe the SE larger front rotors and rear disc upgrades are way more than adequate. You can ask MyFirstYota about that, I believe he has first hand experience.

Like I said though, I'm just putting out what's running in my head. I've seen a set of Skyline R32 wheels in eBay, and thought they'd look cool on the Yaris. I think they'd mount flushed with the fenders, would have to get hub centric adapters though.

Another thing that's been running in my mind, I believe that the rear disc conversion can be done without swapping the axle. You just need to trace the mounting plate from the SE axle or from the xB (the xB would probably require redrilling holes on the hub for the bolts to mate on the mounting plate), transfer it on a strong metal plate, (I'm not an engineer so I don't know the minimum thickness and material, so let's say 10mm steel?). The rear wheels are 5mm recessed in compare to the front (this is true for the 2nd GEN, not sure about the rest), adding the plate 10mm will make them stick out 5mm further than the front. If 5mm thick steel plate are strong enough to hold the rear caliper then I think it'd be perfect! You'll need all the hardware like longer bolts to mount the rear hubs, calipers, rotors, ebrake cables and also will need to weld the brackets for the ebrake cables.

Maybe CrankyOldMan can get better use of the xB conversion now that he owns the Armstrong Racing Vios? Swap out the knuckles up front, not sure if the axle spline count and diameter for the hub are the same though. If it works then you'd have bigger rotors (better stopping power?), and better wheel selection. what say you Crannky? :biggrin: :biggrin: :biggrin:

Thanks! Everything I accomplished was only because of the guys here on YW. I definitely could not have done it without them. Of course I'll be following your progress. It's very interesting to me. I love your idea about fabricating a plate to adapt the rear caliper/disc setup.

BTW, I think those Skyline wheels would look smashing on a Yaris. :thumbsup:

As others have pointed out, you don't need rear disc brakes. Having raced our Yaris at some of the fastest tracks in North America: Daytona, Road America, Indy, and some slower ones that murder brakes, we never ran anything but stock shoes in the rear.

Now if you want the look just press the easy button and swap in the SE front and rear set.

You really don't want 5 lug hubs on a small car like this... The 5-100 just plain sucks for wheel selection. And the 5-114.3 is really only good for 17"+ choices.

Duly noted about not needing disc brakes in the rear, but it'd definitely look better with disc brakes all around.
Swapping the SE rear axle might be the easiest route for the rear disc conversion, but proves to be more difficult cause I can't readily find the axle, and it's more pricey than say you trace the mounting plate and do the sandwich kit. Welding will be required for ebrake cable brackets.
If I were to do the 5 lug conversion, I'd use the xB stuff, it would be a hell of a brake upgrade and cool factors, plus I'd rather do the 5X114.3, didn't you see that ebay wheels that I posted? I think they're beautiful! Might look even better on the Vios.

[CrankyOldMan]

rear disc brakes are expensive and overkill unless youre going to be doing a lot of racing/lapping.

Our resident SCCA National Champion (Jason@SportsCar) has run stock rear drums for years on his HP and B Spec Yarii, says that there really isn't a need to mess with it since almost all of the braking happens up front anyway.

I've considered it for my DD as well, mostly for cosmetic purposes. It's already running Corolla calipers and SE rotors up front. That said, Project 2ZR Vios would be an interesting candidate for a rear-disc conversion. It would also require the brake balancer from an SE, or an aftermarket equivalent.

Edit*

Probably should have read the entire thread before replying.

It's all good Cranky, the thread does cover two topics about disc brake upgrade and five lug conversion. I'm just glad to hear you chime in.

I wonder if we'll see the GR Yaris on our shores? That's five lugged.

I might dump this idea anyway, I've been eyeing some 4X100 wheels already for months. I just thought the Skyline R32 wheels, 16X8 ET30, would look sick on a Yaris, even better on a Vios.

If I ever do pursue it, I'll let you all know.

GR yaris is basically using a scion xd setup for 5lug.

is it the same axle mounting?...i mean 5x114 opens the world to basicly every wheel imagineable.....makes me wonder if the front spindle/hub is also the same "fit"

NO NO NO NO bad...im staying true to my 4x100...but the 1st gen toaster XB that will be soon.....hmmmmmmmm

:laughabove:

Yes, my theory is that the 2nd GEN xB (xB2) also uses the Yaris/xD rear axle frame. If so, then the hunt for the Yaris SE rear axle frame stops and pursue looking for the 2nd GEN xB’s axle frame for rear disc conversion!!!

The front spindle for the xB2 are already pressed in the bearing, they do have the same spine count (26), and I think if you press them out, they’ll fit in the Yaris’ front bearings.

I should ask my neighbor if I can take measurements of his 2nd Gen xB.

[sh0rtlife]

or ask me...ive got an 08 in the driveway...waiting on headlights so i can get it back on the road

im assuming your trying to verify if it into the 07 yaris body?..as well as width and spring pocket local..anything else?

Yes please… yes to all of the above. And verify if the wheel hubs mounting holes are the same… :biggrin:

Also, would you mind removing the splash guard and caliper bracket, and take a pic of the mounting holes? If it lines up when I overlay a of my adaptor plate, then it’s confirmed that it can be used as a substitute for rear disc conversion.
My guess is that the xB calipers and carriers are moved out from the center to be able to take the big rotors.

[sh0rtlife]

ill see what i can do as i need to do an inspection on it...however initial eyeballing tells me that the axle/swing arm is a totaly different animal and the mounting points on the yaris are much further away from the axle as well as the "tie bar" between the 2 sides is about twice the size

that doesnt mean tho that any of the rest of the stuff isnt possibly the same

honestly tho on the "hub" unit i would just walk into any orielys/ autozone(i hate autozone) and ask them to order one in if they dont have one on hand..that way you could 100% verify the mountings

i will get what measurements i can tho

im actualy useing alot of you and compeers data to try and put something together for the gen1 xb that will be coming home soon..as i KNOW discs in the rear would be really nice on it..but also "bigger"...so if i can help figure stuff out in advance i can then be ahead of the game for a swap on it since it indeed uses all yaris bits under it..i mean its a yaris with a toaster body LOL

There are a few xB2 in the nearest Pick and Pull/LKQ near me, but still about 45 min drive, which has prevented me from going, especially now that it's still cold weather. Maybe in the summer time I'll see if I can snag the left and right steering knuckles and rear hubs out of one. I'd press out the front hubs out of the bearings, and take measurements to see if they'd fit in the front Yaris' wheel bearings and drive spline.

The Yaris SE's front rotors are 275mm O.D., which are what I have, the xB2's front rotors are also 275mm O.D.

Yaris SE front rotors:

Rotor Center Hole ID (mm) 55
Rotor Height (mm) 46
Rotor Hub OD (mm) 141
Rotor ID (mm) 130
Rotor Minimum Thickness (mm) 19
Rotor OD (mm) 275
Rotor Surface Thickness (mm) 22

xB2 front rotors:

Rotor Center Hole ID (mm) 62
Rotor Height (mm) 46
Rotor Hub OD (mm) 155
Rotor ID (mm) 145
Rotor Minimum Thickness (mm) 22
Rotor OD (mm) 275
Rotor Surface Thickness (mm) 25

5X114.3 PCD here I come... :biggrin:

[sh0rtlife]

i havnt had time to dig into the rear more, but i have gotten another look at the beam..its much more "heavy duty" than the delicate looking one in the yaris..i cant remotely fathom that the whole beam could swap...tho only measurements will tell the tail.....

as for the slight rotor differances compare the rotors on the xb to the camry..as the xb gen2 from my understanding is closer to a camry than a yaris

The xB2 front rotors are the closest to the Yaris SE's front rotor stats, only difference is they're 3mm thicker, which is 1.5mm on each side of the brake pads.

There are so many Camry rotors, but here's the closest one:

Height (MM) 49.5
Nominal Thickness (MM) 28
Outside Diameter (MM) 275

These won't work on the Yaris, because of the height difference and are even more thicker.
All I need to know is if the xB2 wheel hub will work for the Yaris, and if the rear hub will bolt right on.

[enviri]

all this for rims! good luck on the advnture lol. i vaguely remember that the xb2 rear hubs were a no go when i did research long long ago...and the rear brakes is a drum in disc setup, not the yaris's twisted caliper?

[Neinris]

Yup... Same thing I did for my 4th Gen Prelude S, I used the 5th Gen's rear spindle, rear hub, front bearings, and front hubs. And had to go with the VTech trim front calipers, since the 5th Gen's front rotors are bigger. I didn't have ABS, so I didn't have to swap out the knuckles all around. She looked so good in 5th Gen Prelude wheels. I couldn't find the S2000 wheels for sale at the time. I think I was the first to do it back in 1999, yeah I'm showing my age. :redface:

I think you need to look at your research again, the xB2 rear brakes are not disc/drum set up, they are just like the Yaris'. Looking at pics online, they look the same, the only difference is the caliper carriers are longer, because the xB2's rear rotors are 279mm vise the Yaris' are 259mm. And here are the dimensions for the xB2 and Yaris' rear rotors:

xB2 rear rotor stats:

Height (MM) 30.50
Nominal Thickness (MM) 10.00
Outside Diameter (MM) 279.00

Yaris' rear rotor stats:

Height (MM) 30.4
Nominal Thickness (MM) 9
Outside Diameter (MM) 259

If everything works, all I need to do is mill down the xB2's rotor to 259mm.

Here's a bonus pic, I tried the best I could with paint... The vertical and horizontal lines were center line references, and I lined them up, this is what I got.

[sh0rtlife]

so i hit a yard today for some xb gen2 stuff and they had a yaris...sedan but whatever no good for me

i took off the rear hub then went and took the one off the xb, DIRECT SWAP, in fact i left the drum brake assy bolted up to the xb..so someones going to be SERIOUSLY confused

so for the 5lug disc rear swap you could use entirely gen2 xb rear stuff, from the splash shield out its all a direct fit to the yaris
ill see about posting some pic's...honestly i dont even think you will need to mill the rotors as theres a "slight" offset in the hub itself


for me however im dead set on 2 things disc brakes that fit my wheels..14s on 4x100..and im slowly solving it

That's funny you left the Yaris' hub on the 2nd GEN xB (I refer to them as xB2).

First and foremost, thank you for helping me with my research. That's great news! You've mentioned before that the xB2's axle frame is more robust than the Yaris', that's also great! May or may not need to have to get a rear sway bar.
When I said I'd mill the xB2 rotor, I mean I'd mill it from 279mm diameter down to 259mm diameter. And like I said before, I think this will still fit in the 14" wheels. The stock Yaris front rotors are 255mm, but the front calipers are bulkier, the rear calipers are much smaller.

I'm moving forward with my "Alternative Rear Disc Conversion" as a cheap alternative.
https://www.yarisworld.com/forums/showthread.php?t=63182
I might even produce some mounting plates if others are interested on doing the swap, for purchase of course. :redface:

If you have the time, would you please try to remove the front xB2 steering knuckle, and see if you could measure the outside diameter of the front wheel hub in the bearing, or measure the inside diameter of the bearing? I suspect that will also fit in the Yaris' front bearing, which is 40mm internal diameter.

it litteraly started snowing while i was out at the wrecker yesterday, and my figures hurt like hell, after my last stop at another wrecker, it started really comming down, i attempted to shortcut and back road my way home as the freeway had multiple wrecks n such......in the end it took me 4.5 hours to go 18 miles.....

were kinda snowed in so ill pull pics from my phone of stuff but im not settin foot outside for a few days lol

the real catch on my disc swap is not just the 14s but trying to stay "close" in size on the rotors to whats on there stock, anything bigger up front isnt likely to clear as the wheels are light but a bit pudgy on the inside

Understood man... I really appreciate what you did. We're mixing topics with my other thread, but it's ok, they're both mine! :biggrin:
The weather this Saturday will also suck where I am. But I still plan to go forth with my rear disc conversion. There's a bit of experimentation whether I should use the Corolla calipers or the Yaris calipers. Check the other thread for that info. If anything, I'll at least weld the brake hose brackets on Saturday and finish installing everything on Sunday, when the weather is a bit nicer anyway. Well, I have to finish on Sunday, because I don't have another car to get to work on Monday. :redface:
Today we're expected temps in the high of 80*F!!! I wished that were the case for Saturday.

What I've been trying to tell you is that the rear disc conversion WILL still fit in your 14" wheels. Your current front rotors sizes are 255mm (which you don't have plans on replacing), the rear disc are only slightly bigger, 259mm. The rear calipers are less bulky than the front rotors, so they will clear the 14" wheels. So you don't need to do any other modification, other than you'd probably need a proportioning valve installed if you don't have ABS.
Yes, the xB2 does have 279mm rear rotors, but if you use the Yaris rear calipers, they will bolt on the xB2's axle frame, difference is that the caliper carrier is shorter by 10mm I believe. So you can still use the xB2's rear axle frame for the rear disc conversion if you're saying that they will fit.
Here's an overlay of the Yaris rear caliper on top of the xB2 rear caliper. As you can see the mounting holes for the xB2's carrier is a bit farther out to accommodate for the 279mm rotors.
Now back to the original topic, the 5 lug conversion is not for you if you insist on staying with your 14" wheels. Even though I think that 15" wheels can still accommodate the 279mm diameter rotors in the rear, I'll still mill them down to 259mm.

my issue is id like to initialy buy all the parts used to prove it fits...and lets face it calipers can be rebuilt for a coupld bucks....problem is....disc brake yaris do not exist in wreckers, in all honest yaris are rare as hens teeth to begin with

I bought my parts from RockAuto.com The rotors are as cheap as $16.50 each!

It's also where I bought the parking brake cables.

I'll do you a favor since you did me one, once I install the rear disc conversion, I'll see if I can find a 14" wheel, and see if it'd fit. And if I end up using the Corolla calipers with my disc conversion, I'll be selling the Yaris calipers I bought, I might even make the adaptor plates to go with them. That's only if I end up using the Corolla calipers.

sounds good!

haha hell yeah Shortlife gets to join the rear brake club too :headbang:

fwiw i have a deal in place for a gen1 XB...due to snow ive been unable to pick it up
but knowing the XB1 is neerly identical to the gen2 yaris...that means everything i pickup information wise should directly swap over to it...so ill be joining times 2!...thats assuming i dont just swap the xb1 to 5lug xb2 parts

Are you going to do an axle swap for both or plate adaptor?

These pics didn’t load for me yesterday, just now seeing them. Did actually bolt it on, is it resting on the center dowel?

[sh0rtlife]

no i bolted it down fit was fine hole alignment and dowel both....id venture to say that the "carrier" for the hub and even maybe the bearings are actualy the same parts, where the hub pressed into the unit is the only "new part",,,and when you consider tooling costs..the more a manufacturer can re-use the same parts and only change 1 item in the chain the more money they save

for my swap..im keeping the yaris 4x100.....as for the xb1 time will tell is it stays 4x100 or goes 5x114.....i know 114 opens up the world to infinite wheel options and going big brakes is easier tha route

Did you get to measure the dimensions of the xB2's rear axle frame? Will it fit in the Yaris? I just want to confirm.

sheet ice and snow...give it another couple days or so to melt off and ill get it

Thanks!
I completed my rear disc conversion, and I’m pretty happy with the results. There’s one thing I want to redo, move the brackets that got relocated on the middle bar of the H.
I took this pic to see how close 15” wheels gets to the caliper. Although it looks really close in the pic, I think 14” wheels will still work, but not guaranteed until I find one to test fit. Or maybe a little grinding on the caliper would help make some room. Ignore that fact that my wheels are dirty… :redface:

Don't grind the caliper, you can induce hair line cracking, mine sit that close as well and its fine.

Not me, sh0rtlife wants to do a rear disc conversion as well, but wants to retain his 14 inch wheels. I said I think might still work with14's, but may or may not require grinding the calipers just a tad. He's retaining the smaller rotor size up front.
Would you try and acquire a 14" wheel and see if it'd fit in the rear?

No way its fitting on mine, I have about 2mm spare between the rim and caliper, I will take some pics to show it.

Try taking a picture from the inside.

Dormant, but not dead…

Thanks to Enviri, I think I finally found the front hub that I’ve been looking for!

[remcafee]

excellent, now the real question i have for you is it worth all this trouble to have 5 lugs? lol

Yeah, I’m not sure either. 😅
I might wait again, I just got these free wheels from my best friend, and I kind of got invested in them. I’m about to get new tires, 195/55 R15. Wheels are DRAG DR21 15X7 ET40, effectively ET35 because of the 5mm spacers. They didn’t fit even with the spacers, so I had to grind the high spots down. I installed slightly longer wheel studs because of the spacers. They gave me an idea of how flushed 7” wide ET35 wheels are.

[remcafee]

i ordered new wheels, work seeker cx 17x8 +22 offset A disk face and since i run -2 camber i calculated it to be flush with fender, when thry get in ill post some pics, if youd want my old rpf1s we can talk, they are 16x7 +35 offset

Thank you, I really appreciate the offer. If I would have known that two weeks ago or so, I would have jumped on it without hesitation. I literally just bought brand new tires for these on Monday. Now I'm trying to figure out how to get rid of the old wheels. :laugh:

To me these wheels look "OK", better than the white Mini Cooper wheels that I had anyway. I like these better, because they stick out farther and has a little bit of a lip, but I'm more into the plain 5 star or 7 star pattern.

If or when I do the 5-lug conversion, I'm still going with the stock R32 GTR wheels (16X8 ET30) or Circuit Performance CP22 wheels (16X7 ET35). If I had the money maybe Advan TC4 (16X8 ET35). :biggrin:

Back to the 5-lug conversion topic, the rotors I'm thinking of using are from the 2nd Gen Scion xB. they're the same diameter and height as the Yaris SE rotors, but 3mm thicker. I might have to get the Scion xB's front calipers too, I just hope the mounting holes line up. Also I have to still measure the bearing perch? for Scion tCs front hub, the Yaris' front bearings are 39mm wide. I hope the tC's front hub measures the same.
