ST205 Brakes on a ST, how ? who ? how much ? Options

[Culpable04]

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 ( 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.

lol It's done by the same places that distribute the rotors.


what else do you need to know to make your project easier ?

Dude, do you realize how bad your little "I've got a secret" demeanor comes across? Call it what you will but you're really being a prick. All I asked was what kind of shop was drilling the rotors, just a curiousity question. I have the equipment in my garage to do the modification myself, and already planned on it. You're just dodging any type of financial information because you're potentially making good money off of this. Yes, you've put time and effort into this, but blatantly saying that because of that you're not going to give any information is poor character.

I for one will NOT be buying the rotors off of you because (and I hope I'm not the only one here) if you're not giving any of the rotor information. How do we know what the quality is, the reputation of the company, the warranty of the rotors (heaven forbid one crack and an accident ensue, you yourself could be held liable as the distributor/vendor..........did you ever think of that????). I would MUCH rather spend my own time researching and money testing than deal with you on it. And when I find what works, I'm going to give that information back to the community instead of say "Hey, look at this, but it's a secret so you can pay me."

Oh, and I'm calling BS on what you told me about the 296 mm rotor I PM'd You about. The rotor you're hawking to everyone is 297mm, yet you told me that a 296mm rotor is "too short, the pads will stick out some" yet in previous PM's you said that anything from 296-300 will work. Your sale tactics leave a LOT to be desired. You have been trying to bully me into "just buying the rotors from you" as you so eloquently put it since I first sent you a message. That is extremely poor from a salemanship standpoint. This is coming from a guy who actually runs a vendor site/business, takes care of his customers, and also has directions on his personal site on how to build my own product DIY. If you give people a choice, you'll find a much better name for yourself, and you may find that you don't lose many sales because people would rather pay for your stuff than go through the sourcing of parts and production of the items.

Don't get me wrong man, I (as well as the rest of the community) appreciate the work and research you've done. but you're going about this the wrong way and frankly, your attitude sucks, and I KNOW I'm not the only one who feels that way.
