Hello everyone,

So I have been looking around the forum to find a definitive answer on this topic and I have not come up with it as of now.

I currently have cross drilled and slotted SC400 rotors and calipers on my SC and I'm interested in upgrading to Supra TT calipers. Question is does anyone know if the SC400 rotor is the same size as the Supra TT rotor?

I know the SC300 rotor is smaller than the SC400 rotor, so I was thinking maybe the SC400 rotor is the same size as the Supra TT rotor and all I would have to buy is the calipers and pads to get them to work.

If anyone can give me a definite answer it would be greatly appreciated and would benefit the rest of the SC community. Thanks everyone

They're all different. My SC400 rotors were smaller than the LS400 rotors. My LS400 rotors are also slightly smaller than my Supra TT rotors.

Supra TT rotors are 323mm front and back, i have TT calipers all around and the brake pads on the rear formed a lip so the sc400 rotors are too small. i'm getting TT rotors all around soon

EDIT:
here's the details i found somewhere i dont remember
TT Rotors: 323mm front, 324mm rear
SC400 Rotors: 290mm rear, 275mm front

BIG DIFFERENCE. here's a picture of what's happening to my brake bads, had to file them down. not a huge problem but whatever.

and filed down

It's basically as oldmantan is telling you. The rear tt brakes are huge, and if you use the the sc rotor it'll form a lip like he posted a picture of. The Supra TT rears are actually larger than the LS400 fronts.

Thanks for all the information guys! Just wanted to confirm before I go out and buy TT rears. I wanted to try and save as many items that are currently on my SC but now that I know for sure I will go ahead and start piecing together everything sometime in the near future.

SC400 rotors are:
11.7 (292.5mm) fronts
12.1 (302.5mm) rears
SC300 are smaller.
Anyway, they´re smaller than Supra TT ones.

I appreciate all the information MMCtuner Definitely doesn't hurt to have the numbers posted for others to look back on if they ever have this similar question.

I already purchased the TT calipers and TT rotors thanks to the information from this thread. Can't wait to get them in and put on the ride
