Porsche 6-pots on the front

[Wally]

After half a year of chasing parts and finally test fitting them and even driving a few meters with it, it turns out the volume needed to push 6 pods back in is too much for my (already uprated to 23,8mm) master cylinder...

It seems 996 GT2/3 uses 25,4mm master cylinder diameter. It hard to grasp why 23,8mm is then really too small.. Pedal dives all the way in after you release the brake and brake again. After two, three stumps its back up and very hard/solid, but that just won't do of course.

That was/is extremely frustrating to find out after so long. I am not ready for Tilton clutches and all, so if other good ideas fail, I will (need to) go back to a smaller disk and caliper and be done with it.

It should work. The piston area between 944 Turbo S calipers 38/44mm and the GT2 28/32/38mm is almost negligible. You may have bad piston seals or you arent fully bled.
