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

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.....
