Looking forward to details, PM me if that's easier

Pm sent

well nevermind, theory did not work, its a beautiful rotor, and hat, gorgeous, but not applicable for the gt4 caliper. Dont have the energy or enthusiasm, to spend on ap racing calipers, and try to find a suitable one, lol... nope.

nope, nope. get the gt4 rotors, and shave em, or do the supra rotors, and redrill period. lol....

clears the ball joint by several mm



need to remove the shields. but what not..

whats the specs on those rotors?

299mm x 32mm (11.75 x 1.25)

problem is they are on a slightly larger hat. they require a hat with rotor bolt circle of 8 x 7. Thus limits the friction area, a lot. the gt caliper is literally hitting the bolts, before it grabs the whole area.

wilwood offers 12.19 x 1.25, but then you get into finding a way to mount the caliper part (160-11835 )

now the calipers from ap racing are part number CP8350 Four Piston Forged, but then the bracket adapter is unknown. I dont think they sell them.
at any rate, its boring to keep reinventing the wheel.

I have found this guy

i may give it a try.. lol/

man I love your dedication dude.

way to keep developing this mod along.
those are some very pretty rotors

Ugh! sorry it didn't work out.

That sucks... Hopefully you can do a return and get your purchase price back at least.

ill keep it, i have and extra hub, i want to play with... maybe in the future i may go ap racing ...

Im thinking...how much more would it really cost to get AP or DBA to custom make a rotor?

we dont need a custom rotor, there are plenty of rotor discs, out there, and wilwood sells several 5x3.93 hats in different offsets. we need a custom hat. but with that comes numbers $$$. im pretty sure we can come up with something viable, the question is, price.

the other problem is, rims, most bbk wont clear unless 17 or above, and unless the 6gc is featured in the next ff8 , aint nothing good coming for us.

I asked DBA about a rotor....basically...no was the answer

Ive fixed a couple mistakes on the front hub and caliper prep on the OP as well as some more detailed info on the rear caliper mounting.

There are still a whole bunch of details I need to address that I hope to clear up this winter. Hopefully we can get this ironed out over the next few months


I would like to get the Cadillac Catera rotor info and add that to the options list as that has worked for a few members

again, if anyone see's any mistakes or inconsistencies in the OP just let me know

my own search for new front rotors has begun, im not sure how long my current rotors will last when I start tracking


ATTENTION!!!!!!


I found a pretty cheap ($360/pair) 2-Piece front rotor pair for the Supra Non-Turbo.
Spec:296x32

Its made by a brand I have never heard of before. I myself probably wouldnt trust it for track racing but for spirited street stuff it should be fine.

I cant find the rotor listed on the site but here is the link for it on vivid racing and a link for the disk replacements on the company site. The supra turbo and non turbo may share the same hat, I am not sure. These would have to be re-drilled to 5x100 of course

Ill have to inquire to get some more info on these and whats available.
If only there was a direct bolt on 5x100

Lol my search for a bolt on rotor is done for. The biggest issue is the hat. It has to be made. I have not found a single company that mixes and matches. The hat sizes wilwood offers are too big.

funny thing is that I do have a connection with someone who would be able to make hats.
He had hats made for his front and rear rotors on his RX-7 so that he could get the offset he wanted.

I could inquire. As long as we pick a disk that we all would use (I dont think he would be willing to make 3 different hats)
Sucks all the different disks probably have a different PCB

Don't mean to throw this in the mix, but has anyone ever seen the twin piston GT4 brakes in person. My guess is that they use same 315mm rotor according to Toyota diagrams. Googled it but nothing came up. I see one clip for sale locally that has them

Yeah front and rear use 315mm disc on the gt4. I've just done my conversion yesterday

well, points for the homebuilder... lol...



the oem supra rotors.....

not to thread jack, but im so happy someone else is running trd lug nuts!! Price is a bit shocking but the design is awesome!

something no one has mentioned on this thread is the need for a proportioning valve. the gt4 rears DO lock up before the fronts without the weight of the rear differential.

Are you referring to swapping it out with an adjustable valve or with the Stock GT4?

This recent article featuring Orido supra (Japanese race car driver who also appears on best motoring


Read left paragraph. I guess these brakes were really awesome for their time. When Toyota made quality parts

an aftermarket adjustable proportioning valve would be a wise investment.

Mr Celica if the month beams extraordinaire said those are real hard to find tune. Or wait never mind the member who had a red Celica with gtfour brakes and rear diffuser with a 3sgte swap.

I haven't had my rears lock up before the fronts but it is just over the line where it could. My arrangement may be unique to that though.
If you want a more close to stock bias then yes, you will want a bias controller. But I believe the 300mm front and 315mm rears give a more even bias to the car.

I guess you MADE the supra rotors fit berto!

the rear end has kicked out on me on 3 separate occasions.

once during a panic stop because some jackass was doing 10 mph on the highway

twice when I hit the brakes on a curved, downhill highway off ramp.


In everyday driving its not an issue. But the above situations are not uncommon. They DO happen, and you don't want the rear end kicking out to make things worse.

I'm running new Michelin Pilot sport tires, new rear struts, new rear top mounts, new poly bushings, new SS lines, new everything. Also my swaybar is at the softest setting. Therefore I don't think there is anything wrong with my setup. Proportioning valves are cheap, easy to install, and not that hard to setup. Just do a number of hard stops in a big parking lot or wherever until the rears stop locking up first. I'll be ordering mine soon and installing them over the winter.

You guys can do what you want, just be careful and be prepared to countersteer

I think its just the driver... bahah never forget that moment! Or the look on her face!

And the car was stock when that happened, now factor in a rear caliper that is oversized for the application

Ill throw a section about it in the OP.
I can understand that not every setup is the same and just because mine doesn't do it, doesn't mean that everyone else's performs alike.

I figure if you are willing to go through the effort of doing this swap, it shouldnt be that much more difficult to plumb in a Bias Controller.
