          IFAIK The caliper is much bigger overall than the 996 (996.351.425) it also accept's thicker disks... it also has bigger pistons, still 4 pistons per caliper...

          I have posted a drawing in a thread which shows the size differance... and I think it was the GT3 Big Reds I measured... It has the part numbers listed on the drawing...

          Hope this helps...

          Thats a good price with the caliper brackets...

            just a note to bare in mind, the gt3/c4s caliper can not be used with the 323 a8 disc! The a8 disc is 30mm width and the gt3/c4s caliper is designed to be used with a 34mm width disc, so you run the risk of popping the pistons out of the caliper as the pads wear, you are going to need a 34mm width disc or a custom rotor and bell arrangement

              Yep, totally agree. I am using these calipers on my Skoda. You can't use these with a 30mm disc.

                You can run thees whit the A8 323mm disk! Actually thees Custom Made Carriers are made to yous whit the A8 disk. It works perfectly i can tel you. Oky you must replace the pads en disks before the totally worn out

                  Are you sure about that? I assume you must work for brembo, im no braking expert granted, but surely if brembo have designed these calipers to be used with a 34mm disc, they have built in some design limits and to immediatly take 4mm off those limits and thats with brand new discs and pads that will wear out even further, surely this is a risk thats not worth taking especially with something so critical as brakes! But thats just my 2p worth...

                        wich are the sizes of these 4 caliper pistons??

                        42/38 maybe??

                        the original 996´s has 40/36 can be??


                        i think that the price for these calipers with custom made carriers for 323 discs are very very cool

                        good luck David

                              these are part number
                              996 351 429 - 996 351 430
                              They fit a number of Porsches....

                              996 Carrera 4S - Year 2002 - 2004.
                              996 Turbo - Year 2001-2005.
                              996 Turbo (1999-2005) (TURBO).
                              997 (2005-Present) (CARRERA 2-S)..
                              997 (2005-2008) (CARRERA 2-S)
                              GT3 Etc...
                              Maybe GT3 Turbo

                              The disk's I have from a set of these are 34mm Thick (listed On Fleabay Linky)

                              Piston sizes are 32 & 40mm from what I measured last week....

                              Cant speak for the fitting... But these guys must know if they have fitted them...

                              If using a smaller thickness disk could you not use bigger dampers & shims to make up the differance??
