Default Brake Options

Can anyone tell me the difference (rotor diameter, caliper pistons numbers, diameter, ???) in brakes for JL9, J55, J56 and/or other RPO's. I want the biggest diameter rotor and strongest caliper.

Unless you want a Z06, here are the base and Z51 sizes. The calipers are the same.

Base:
front: 12.8 x 1.26 / 325 x 32;
rear: 12.0 x 1 / 305 x 26

Z51:
front: 13.4 x 1.26 / 340 x 32
rear: 13.0 x 1 / 330 x 26

Actually, the pistons on the Z51 rear calipers are slightly smaller than the rear base brake pistons. I wouldn't sweat the difference.

Thanks so much for your help!

What are rotor dimensions for the ZO6 brakes?

Do you have part numbers for Z51 and Z06 rotors and calipers?

Do spindles and hubs P/N's vary from Base to Z51 to ZO6 or are they all the same?
