Yes...there have been some developments Bit of hard driving produced some unwanted results lol

Also Im slowly ticking off the things needed for some light autoX racing in the future and on the list was the brake pads and rotors.

The brake upgrade came with spme unknown chinese brand "CAC" brake pads and had some rust spots and scratches on the braking surface even after some heavy footed stops and lively driving through the windys for 6 hours and I don't pad slap and so the rotors are at the brake shop getting machined and I have ordered some Bosch pads.

I still get a staff discount at one of the part stores and so thats what pushed me towards the Bosch Blue pads at $117 front and rear versus Toyota which was $267 front and rear.

What type of brake pads do you guys run? and what have you used for competition racing?

BTW, I checked and my brake line bracket also hits. I will be relocating my brake line brackets.

I looked at it but the brake line doesnt have much room and still goes over the top of it and the brake line was a bit tight when I shoved it down that side to see how it would fit, I think you need a 2-3cm longer hose?

As you already know, my disc brake conversion is underway. I already have all the hardware necessary to complete the conversion, minus the materials for the brackets. But I'm looking into replacing the brake line from the hard line under the chassis to the caliper with one rubber hose, instead of transitioning from hardline to rubber hose, to hardline, to rubber hose connected to the caliper. This could give me the opportunity to reroute them, and just remove the brackets that hits the frame.

actualy the 4wds are not rare..they just never left japan......every time ive looked thru at them for importing theres atleast a couple up for sale..and CHEEP...if someone told me i could swap the 1.5 onto the 4wd trans with 100% certanty id have pulled the trigger on one

I have not seen a 4wd older one for sale or wrecking for parts here yet so idk rare in my experience so far. I keep looking because I want to see if you can get a manual corolla carib 4wd box to work with it which would make for a really fun car to drive.

Also I will take more pics when I change the suspension back to lower mount holes to show the contact points and why not to change the suspension mounting points.

youve got my attention with that..which rolla box? and assume said rolla box would mean 1.5 or 1.8 swap too?

the exporters ALWAYS have a few of em listed tho there isnt always good pic's...ive come across a few of the listings tho that had pics galore , and can state with some certanty that the driveshaft runs right down the center of the car and connects to what looks like an old toyota pickup axle...but like i said, the fact that they all have a teeny tiny engine has kept me from pulling the trigger as no one seems to know anything about the trans or swapability
but lets face it the chassis will take whatever we want, its a question of "how" do you keep the 4wd...so what trans were you thinking?...i mean hell at that point you wouldnt need a factory 4wd unit, you would need a rear axle, driveshaft and trans and rear axle mounting

i just killed off the "new" sed of pads from my rotor swap, they didnt last long and i didnt expect them to, swapped out for full ceramic..so far so good

i would personaly run "hawk" but the price hurts

I have personally not seen Hawk for sale over here, We have EBC race brakes here in Auckland and maybe in the future I will go this route if it seems needed.

Got the job done today anyway guys after my pads and rotors arrived this morning, They barely skimmed 0.5mm from my rotors and they are mint again, New Bosch semi metalic pads feeling great already.





Also check out how terrible these "CAC" brand brake pads were. Front left was normal looking while the right is half glazed as seen below.


And the back left and right are far worse.


...and now I need to repaint the wheels as they keep chipping.

hawk being a race company isnt one of those things youll see on a shelf..well..anywhere

ive run a few grades of their pads in my alfas and the pads were worth every over priced penny, but i havnt been able to justify it for the yaris...yet

Fair enough, I always used bendix in the past but they were ceramic and I read they are worse for light track use than semi metalics.

Need to take her out to really bed in the new brakes, but been stipping my wheels and getting them ready for a paint.

FWIW i remember something about not ever wanting a "flexible" brake line longer than 15? inches due to "swell" under pressure, and anything that long MUST be braided, with that said i have done up to 23 if memory serves on a 4wd conversion ford van

I see why that section in the rear is broken into hard line, rubber hose, hard line, then rubber hose again, to shorten the rubber hose length.

The slight swelling under pressure is what I was banking so you'd get less pressure in the rear for your rear disc conversion.

I'm keeping the hard line in between the two rubber hoses that I have, but I'll straighten the hardline, to extend it a bit and be able to tuck the rubber hose and not use the original bracket so it won't hit the frame.

chop the original bracket off and weld it on inside instead of the top, theres a thread on here I read where they did this. Not sure if they got new hardlines made.

That's exactly what I had planned on doing, but my buddy (who made the plate for my disc conversion) can't make it to help me this weekend to install the disc conversion. He has a welder, but he lives an hour away, I'm too lazy to grab it during the weekday. I'll probably end up just riveting the brackets in place.

I bought the stock hard lines supposedly for the Yaris SE, PN 47324-52100 & 47323-52110. But having a shop make them would probably have been cheaper.
Well, at least I can use them to mock up about where to put the rear most brackets before I straighten them out a bit to stretch them to reach the bracket that will be relocated.

Are the TRD springs that much softer than the Tein's? Or I guess it's just the angle of your pic that makes it look closer to the frame vs mine?

the tein are softer but also its the Flex Z so I I can shorten front and rear shock absorbers to match the ride height, So yeah the shocks are shorter even than my short trd shocks which I believe are shorter than stock as well.

Honestly there is a guy selling a set of cusco coilovers second hand and i kinda wanna get them, the fronts are stiffer but the rears are the same as tein, I could sell the flexz set then maybe, would have some decent track shocks and the tiens for the road. Just need to get my guy certified and plated for adjustables. If I buy the cusco i may even just swap the springs depending on how worn they are. Also do you run spacers? Plan to buy some so i can stop slight inner tire rub, Im thinking 3-5mm will do they only just touch full lock.

flex zs are stiffer than s tech springs, the flex zs are 4ksprings front and rear

i hate the fact you can find this stuff used.......
