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

[06YarisRS]

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?

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.
