Really neat calculator! Thanks!

I just calculated mine ('86 944 Turbo - early brembos) and I got 1.627. I guess this is up to specs.

Your 28/32/38 is probably correct. Those are the seal sizes listed in PET. It also makes the hyd bias the same as the non-pccb TT. (A whopping 1.93) That explains why it burps the front abs over every little bump/dip.

the setup I just snagged comes out to 1.72 (late 951/968 front, 951 rear)

i didn't read the whole thread, but since the FEWC porsches have more weight over the front axle, wouldn't the front bias need to be higher than 1.6 in these cars to account for weight transfer? should I throw a proportioning valve into the plan just in case?
