What I have assemble are C-5 brakes (4 piston PBR calipars/13" rotors) on the frt with a complete 4th gen Rr. axel out back (2 piston PBR calipars/12" rotors). The master is an 02 Disc/Disc 4th gen plumbed to a third gen 1LE proptioning valve, out to S.S. brake lines. This is all sitting under 91 WS-6 Firebird w 17x9 rims and 245/50R17 rubber.

Is this a good combination does anybody see any conflicts. Thanks

 

4 piston c5 caliper? havent seen them, c6 maybe, but they are 6 piston.

Im running c5 zo6 front calipers, 2 piston, and 4th gen rear discs. Im using the factory booster, a ls1 master and a 1le prop valve. Works fine.

 

That's good to hear. I was worried about rear wheel lock up bought a wilwood adj proportioning valve just in case.

Your correct; to much daydreaming out loud. I've got everything installed on my 91. I bought it with a blown eng. Decided to put everthing on it, brakes wheels&tires, suspension while i had it down putting a 383 in it. Gas prices made for a change in plans. Now going with a Ramjet 350 cam and the basicly stock TPI, instead of Hot cam and modified Lt-1 intake.
