hi guys, ive managed to get hold of some 996 calipers after seeing and reading about the conversion, so, the part numbers of the calipers i have are 996. 351. 425 and 996. 351. 426. from what ive read am i right in saying these are the front calipers off a 996 turbo? i have 330mm brackets to use with them, i have read that i need alfa front discs but im unsure of exactly what model alfa they are from? i also have read that the pcd has to be re drilled to suit 5x100 stud pattern, how much is this likely to cost?? last thing is that the caliper link pipes have to be swapped so the calipers can be mounted other way up, question is is the bigger piston supposed to be at the top or at the bottom of the caliper when fitted? i have tried to search for the answers but ive not managed to find any direct answers to my questions, thanks in advance for you help.
