Thanks, good to know! I have all the bits necessary to do this and was thinking of doing it when I have everything apart to install my coil overs when warmer weather finally arrives. Any suggestions on a 'perfect fit' bias valve? I remember when we did 'Medium Red' brakes from the 944 Turbo 'S' on the regular 944 we would use the 928 S4 bias valve and when we did did the BMW 320i front brakes on the 914 we would completely take out the factory bias valve and install a VW 'Tee' bias valve fitting instead. Does nothing with a Porsche part number on it work?

just be sure you know what you're doing first. rear-bias settings that seem fine in a straight line on dry pavement may be to aggressive for wet weather & curves.
