I have an opportunity to get a set of STI rear brembo for my car.

I wondered if anyone could tell me if they would fit?

The STI rear brembos are: 12.3" diameter, .8" thick, 2-piston, fixed-position calipers.

Our 350z rear brembos rears are: 2-piston caliper with 12.7" x 0.87" vented rear discs

Are the STI interchagable to our Z. Please please help me out.

Thanks

 

they are the same caliper. You would everything else from a track Z.

 

The rear calipers are not the same. The Sti rears have a 4.5 inch distance between the mounting bolts. On the Z and G35, it's some wierd distance, somewhere between 4.75 in and 5 inch (doesn't round to a even number in metric either).

The Sti rear pistons are 38 mm, I think, whereas the Z/G35 brembos are 40mm in the rear.
