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.

Ok, I've got a bead on two sets of front calipers right now. Good news is that they're cheap enough that I am probably going to buy both and flip the one set.

The rotors that you're using, are they slotted or anything??? I'd really like to know what they're off of to see if I could snag a higher quality piece like a Baer Eradispeed or a EBC rotor.

Are there larger rotors that you've tried that worked but had to be shaved down? Reason I ask is because I don't mind bracketing out the caliper, I've got the 18's so the more heat dissipating rotor I can get in there the better.

Thanks a ton dude.

you're gonna flip the calipers ? why ? to make money ? no way ? not you ? I know you are kidding.


since it was already specify that the rotor only needs to be re-drilled with the correct bolt pattern and you KNOW that, and so everyone else, wouldn't telling you which rotor it is, imply that you could do this on your own, using my information for it ? and everyone who bought a set of rotors ( not for sell anymore ) would have gotten all the needed info to get replacements from somewhere else if they wanted to or in case I fall dead or crashed due to brake failure.

for yours to have a higher quality don't you need a measuring point of the quality of mines so you can raise the bar ? you just assumed, didn't you ? or you have insight info on that too ?

I'm glad this gave you something to do at home, now go and spend the money poor guys like me are crying for, and you have extra laying around, just to prove my point.

you never had the intent of buying my rotors, and trust me, after seeing how you behave and disrespect anything is not done for / by you, there is not enough money in this world for me to sell them to you. you said you are a technical guy, where is the technique here ? get my specs ? and use them to buy some fancy discs with a lot of holes in it to show off pretty pictures online ? hmmmm there is a word for that type of people on the dictionary and it's not technical.

I WILL NOT SELL any rotors, unlike you, I don't NEED this money, but I guess you also knew that, because you already have a full opinion of my personality and I'm sure you would not have drawn that out of internet alone, like internet knights and keyboard warriors do.

There are more than 5 guides online that show you how to do this, yes, just use google and see how that goes, will it be reliable ? sure, google says so.
here some info you didn't post or didn't know

the benz rotor they used on the 7th gen is NOT available in the states, and in case you were to find one, you have to trim down a few mm of the caliper for it to align with the rotor, so let's see, the rotor has to be re-drilled, the caliper needs to be modified, and not available in the US, those were the same issues with using a ST205 rotor but we didn't have to re-drill them, so what was accomplished there ? NOTHING

there is another member here who here a write up on this, excellent write up, what's the issue with it ? he used ST205 rotors, NOT available in US and expensive to buy / ship from overseas. I'm a very lucky guy, I sat down, though about it for a second and said " hey let's try this X rotor " and it worked perfectly, so I must be the luckiest guy on earth, I mean, as many rotors that there are out there, and I just got the right one.


Mod please lock this, let's all wait patiently for Fastbird to find rotors that work, I'm sure he'll find one, in the end, just ask yourself, was it worthy ?
with the money you'll spend on this alone, you can just buy a Big brake kit meant for the 7th gen for ~ 800 and be done with it and have money left, but is a personal matter to you now, so just go ahead and prove yourself and the world that you can do it, and we will all stand and applause your success.
