Hey guys. Just had a quick question. I tried searching, but for some reason couldnt find the answer though Im sure its been addressed here before. Is there a difference between the caliper itself, between our FDs oem rears and the 99 RZ rears? I know the RZs had a larger rotor, and therefore a different caliper mounting bracket, but was there a difference in the caliper itself? Reason Im asking is I am running the Racingbrake rear BBK, and was wondering if I need to be running a RZ caliper or if my stock ones are ok to use.

 

The brackets and rotor size are the only difference. The caliper is the same.

Add these and they are the same as the RZ brakes
F124-26-281 (for 17inch wheels - ie the larger rotors)

Sorry to bring up an oldish thread but I am trying to match my rears to my stop techs up front. I don't/can't pay for the racing brake kit as it's just too much. Where could one source the bigger diameter rotor for the rz bracket? How does this setup differ from what is sold by rx7store? There's nothing wrong with my calipers but I'm due for new pads and rotors in the rear and am looking for cheapish options.

 

Edit...I have the caliper figured out. Does anyone sell a 314mmx20mm rotor that is slotted for the FD?
