Ive just bought an S3 and i already had a set of Willwoods spare so thought i might stick them on. however im concerned that with them being Four pot the Mastercylinder might not handle it and ill end up with soft brakes.
So i just wanted to know what size pistons are in the fourpot calipers you guys run.
Willwoods are 44.2mm so total surface area of 12275.08mm compared to the 9160mm of standard surface area.
Any help is much appreciated
