I have PFC 01's on all four corners on my 964. They are freaking loud on the street. Dell is correct in saying that they don't really quiet down until you really get them hot. They'll still squeel occasionally on the track as well. I am lucky that I can swap all four corners in about 20 minutes on my car but its a bit more difficult on yours.

You might do that if you had ceramics which had the same bias valve as the standard setup but bigger rear disks which meant they had a bit too much rear bias! The extra 10mm on the front alcons I run are about perfect I think with RS29 all round.
