I am getting my car closer to running some Vintage Races with a more authentic organization next summer, most recently installing a set of early S calipers in place of a set of 951S Brembo 4 piston rear brakes on the front of my 914-6GT replica. Any suggestions on pads for this type caliper? Was running the Porterfield R4 pads, currently have padgid orange compound which came with the calipers. Seem to be quite difficult to bleed succesfully, your thoughts? Already have stainless pistons installed from a prior owner. Good/Bad? Car seems to alternate from pulling one way then the other under heavy braking. Did not do this with the Brembos...not at any speed. I miss them already! Using ATE Super Blue. Any comments about racing with these brakes, I mean real, wheel to wheel racing, not AX, or street racing, are welcome. I can see backing up my braking points a few feet already! Thank you, and hope to see you at the track.
