A few months back I started the research, measuring, freezing fingering task to fit ST205 brakes on a USDM Celica.

the first step was to pair a ST205 caliper on USDM system to see what were the differences, well, the bolt holes are EXACTLY at the same distance, but unlike our stock calipers, the ST205 calipers have no thread on them, reason being that these ( st205 ) calipers are mount on the back of the knuckle, not on front like the stock ones, so this presents the first thing we need to work on, the other issue was rotors, no need to remind you how small the USDM rotors are, so they are useless here, we had a set of ST205 rotors, but there are 3 main problems with them, first, in order to fit them on our suspension, the caliper has to be modified, this modification involves grinding a few mm ( ~ 10 ) out of the bracket so the rotor falls dead center with the caliper, the second issue is that with the location of our holes on the knuckle the caliper can not accept anything bigger than 300 mm, and the 3rd problem is that ST205 rotors are not available in the states, the cost for them overseas + shipping charges = way out of my and most people price range ( ~ US$600.00 )


so ok, the first thing I did was ordered a set of IS300 as there was a rumor that they'd fit, hmmmm no, they don't, but at least with them I took some measurements that helped me get on the right path, I got on the phone with a partner in business, and using the measurements and the specs of USDM and ST205 celica, we came up with a rotor that seem to fit " in theory " lol.

I got such rotors a week later, and we tried them on, the fitment was PERFECT, for the caliper we, took the knuckle off and thread tap them, so no we have how to bolt the calipers, and have rotors that fit, went to tried them on the car, and guess what ? everything works perfectly, just one last thing, the wheels didn't fit, so right now we're waiting for my spacers to get here, so fit them on.

to resume..
here are the step to fit ST205 brakes on a USDM celica

1. take the knuckle off the car and thread tap them thread taps are available anywhere, buy matching bolts for the thread you are tapping ( grade 8 bolts please ) use a 1/2 x 20 tap or finer thread. ( the one used on the pictures is 9/16 x 20 but no need to go that big as that will require to drill the hole to make it a little bigger.

2. order these Custom rotors from me tongue.gif ( before you ask, if for some reason I can't supply them to you anymore, all the specs are sources will be posted, I'm not gonna screw anyone )

3. install, you'll most likely need new brake lines as the stock ones are not long enough, so take the opportunity and buy some Stainless Steel lines.

for brake pads, go to your local dealer, ST205 brake pads are exactly the same as Supra Twin turbo brakes,

4. if you need spacers for your wheels, I can supply those as well, I'm working numbers to offer a discounted price if you order rotors and spacers at the same time.


now enjoy the pictures, and let me know if there is any question.

























*the pictures show the rotor a little rusty, because they've been outside for a while, also things are just mocked on, not tighten as the calipers are still being painted. what you're looking at is a work in progress.

These are the spacers I'll be offering to everyone, hubcentric, made out of forged Aluminum, CNC machined, with longer studs. they'll be offer on thickness of 10 mm, 15mm, and 20 mm.

so (im just making sure) a tiny bit of grinding rethreading some holes and they will fit? and will bolt straight in to McPhearson Suspension set up?? (apart from the wheel spacers)whats the size (radius) of your ST brake rotor?

HHhhmmmmm

You will also need the rotors on the pictures, they are custom machined for this set-up.

So whoever needs a set can just let me know.

These rotors are 297 mm

Can you supply custom slotted rotors (front & rear) fit to match an ST205?

the only thing stopping me from developing a rear rotor to fit with this set-up is that I still don't have a set of rear calipers, once I get them I'll get on that, I already have most of the specs, but don't wanna go blind at it, need rear calipers to take actual measurements.

BTW front rotors, can be drilled, slotted, plain, or slotted / drilled all at the same price, US$200.00 shipped, some of you are in Canada, so the cost of shipping will be different, but not by much, as shipping rotors even within US cost some money anyways, and for those wanting the whole front and rear set-up don't be afraid, I'll be working on that as soon as I get my hands on some rear calipers.

for ST205 I have a rotor that will work for the front, for the same reason described above I still have nothing for the rear, but I do have a rotor that can fit on ST205's front

how does a caliper fall dead center on itself....


and #2 you lie.

but great work dude this is yet another beneficial contribution to the community to make these cars one bit better thumbsup.gif

cool, i guess i'll wait til you get the rears sorted out. the rotors will need to be replaced about 2 months from now and i may as well get slotted rotors from you than have them sourced from Japan at a higher cost.
and thx for confirming that supra TT pads are the same as st205s. i searched & searched but couldn't find a solid confirmation if it was true.. until now.

Oh come on, you know what he ment (I would hope). The ROTOR falls dead center of the caliper, just to clear that up. Typos suck.

Why does he lie, what are you talking about?

He's refering to my comment on the chat room about posting the specs, but after all the work I did, and the research, plus testing, is just fair that I get something back from this. plus, the price is not out of anyone's range, is just what rotors cost anyways, of top of that, I'm working on doin g the same for the rear.

Can you get BETTER rotors somewhere else ? yes, at the same price ? NO.

This rotors are based of a new luxury car, so irt's not like I can hop on Ebay and grab them for 30 dollars like you can do with civic rotors.


Thanks for all the comments to everyone, I appreciate your inputs ( positive or negative )

Culp, what size wheels are you running on your setup? Where is the clearance issue on the wheel? Is it that the actual backside of the face of the wheel needing spacing or "other"?

I have 16s, we tried it on jim's 17s and he needs at least ~7mm to clear the calipers, this kit will fit on 16s or bigger wheels, but the issue is the offset of the wheels,thus why we need spacers. If you have wheels with an offset of ~35 i dont expect any issue for the kit to go on without spacers.

Interesting. My 18x8's with the +35 offset would probably look better with something like this hiding behind it............

Fastbird, start hunting down your ST205 calipers, or if you're not too picky about the CELICA name on them, I can get you 4 piston toyota calipers re manufactured by Toyota, they are exactly the same calipers, even use the same brake pads and part,s but they don't say Celica on them. PM me for details if interested.
