Can the SC 400 2 pistons fit the back. I doubt it due to size and no one here has said anything and im sure if it could be done it would have.

 

SC400 has 2 piston calipers in the back?

 

I think he means putting the front calipers on the rear. I don't think its possible but i could be wrong. From what i know, the Supra TT rear calipers are the only once that are direct bolt on.

 

Are they 2 pots? And yes luxor vteruni is right. Im doin the ls brakes in front and I wanted to reuse my SC fronts in the back. But I guess not.

 

Yes the TT rear calipers are 2 pistons, and if you are doing the LS400 upgrade i wouldn't suggest keeping the old once. With 4 piston in front and 1 piston in the back you are going to have some uneven wear on your pads/rotors as well as some funky braking during high speeds. The TT rears cost less than the the TT fronts but still arent very cheap. Trust me ive been looking for a set a while now. I suggest to make sure you have the budget before starting the project just to be safe, and also wheels that will clear the brakes. Dont want to for get the wheels

Good luck!
