I am in the process of switching over my brakes - Brembo BBK front and stock rear (powder coated to match). I have located a decent set of 1999 M3 rear calipers that I could get powdercoated and then switch with my original calpers. However, in looking at realoem.com the part numbers are different (not a big surprise) but the pricing is quite different for the M3 calipers versus the M roadster. Both fit 312 x 20 mm rotors so they should be close, however before I spend the money I would like to know for certain?
Anyone know if there is a difference between them besides for price? If it works out I will have my old rear calipers for sale this summer for anyone who is looking to do the same.

Quote: | Except for the entry point the calipers look the same. | Ron, do you know the difference in rotors between the M Roadster and M3? I have heard a couple people say you can use M3 rotors, but many say no. I have never tried it myself.
Is there a difference in diameter or the hub backspacing?

I am running E36 M3 rotors all around with no problems.

While we are on the topic, how much additional line (or is it a different andgled fitting thats needed) to swap to a E36 M3 caliper. I am just thiking about how brake kits are offered for the E36 M3 and not the M Roadster. What would it take someone to convert over?

The Z3 comes in from the side and the M3 one enters at the back if I remember right. Maybe a longer looped line would work but didn't go there.
