Default Brake caliper upgrade and interfearance.

Will C5 brakes caliper work with 15x3.5 prostar front runners? If not what brake calipers or upgrade can be used that will clear or can be made to clear on a c4.

If you're running that small of a tire/wheel setup, why are you bothering to complicate life by transplanting later calipers?

Default Caliper adapter brackets

I've got a set of the caliper adapter brackets to install J55/Grand Sport calipers on early (84-87) C4's. PM me if interested. They are brand new and were made by "he who lives in Washington state and whose name shall not be mentioned on this forum."

fastac4,

You would also need a set of J55 rotors to make this work as well as abutment brackets.

To summarize, you would need:

2 - J55 or Grand Sport calipers
2 - J55 rotors
2 - abutment brackets
2 - caliper adapter brackets
2 - wheel spacers (just going by what rodj stated, as I'm not 100% certain. I was going J55 w/17" wheels before I decided to go w/C5 Z06 calipers. Price for C5 setup was a good bit cheaper than going Grand Sport or J55 route.)
