Is it possible to put the st185 dual piston calipers on the front of a celica st without modification?

You need bigger rotors from what I understand...ST184/5 or ST204 rotors should work fine. My dual-piston All-Trac calipers are on their way and I just ordered Brembo rotors for a '90 Celica All-Trac. I'm going to run Satisfied ceramic pads in front as well. I'm almost positive that everything will bolt right together, but in a couple weeks I should be able to let you know for sure.

hurry up Coomer >>
if it works, i can sell my st185 calipers as well

Hmmm...increasing the size of the front calipers and switching to rear discs, would a new proportioning valve not be a good idea as well?

The calipers will bolt up just fine, use the ST185 rotors.

Ok looking at coomer and doggy's post it looks like the at200 rotors will work on the front.

But when I switch to rear discs will I need a new proportioning valve?
