well the 3000gt calipers are pretty much the same as the R33 calipers but they hav MITSUBISHI on them rather then NISSAN...and the way i see it, R33's end up on nearly every nissan that didnt get them and cressidas too, so they must be ok
related.........further research shows that an ST205 Celica GT4 (car i was gonna get before the vr4) has 130mm (same as pre face lift vr4) caliper spacing for a 315mm,32mm thick disc.
Couldn't you just use that caliper with a JZA80 Supra TT front disc as it's 30mm thick.....which is the min for the GT4 disc?
Yes it will bolt up ..the dsm guys use them. I think the real technical part is finding the right width rotor. Some people use mustang cobra and some use nisan 370z. I am going to try to get the right info........the Cadillac ones wont fit because they are 6 hole lugz.
