C5 brakes in a C4.
I apologize is this has been asked before but if it has I can’t find the thread on it. What all is entailed other than the obvious calipers and what not? My car came stock with the big brakes. It’s a 94. Do I need to switch out the spindles out will the C5 calipers bolt right up? Do I need to change the master cylinder also? Well the calipers clear stock 17” wheels?
Thanks

1) I believe that there are adapters you need in order to bolt on the C5 front calipers.
2) I don't think that they will clear the sawblades but I believe that they do clear the 17" A-mold wheels.

If your car came with the J55s, its not much of a step up to C5 brakes, but all you need is all the C5 parts + an adapter plate to mount it. I have them on my 88, I bought stainless lines for the 88, not a C5 part.
There are issues with fitting under the Sawblade wheels, usually they dont fit so the consensus is that you'll need a wheel upgrade to be 100% sure. A-molds/5-spokes from the ZR1 or GS car, or similar aftermarket, they do fit under.
But if I had J55s already I'd probably look into the C6 Z06 brakes, and new wheels so they'll fit.
