Tye

I've got an 87 944S. I've purchased the complete front suspension/brakes from a 968 and also the rear rotors and calipers. I think that I'm all set up front, but I've read that I need small spacers (about the size of a thick washer?) for the rear calipers.

Does anyone know if this is so, and if so, what dimensions? And does anybody sell them? Anything else I should know about??

One other question: any recommendation on the brake limiting valve? I'm looking at the 33/5. BTW, this car will see mostly track time.

Thanks!
