DC2 - Porsche brakes

[speedminded]

ok, so 4.41 x 2.88 for the boxter rear calipers = 12.7008

and 5.08 x 2.16 =10.9728 for the gsr fronts

and just for comparison's sake, 5.85 x 2.27 = 13.2795 for the type R fronts

so just by the basic numbers, it looks like your brakes are somewhere between the itr and gsr in terms of swept area - although this is difficult to say for certain since they aren't perfectly square anyway, and the shapes are all different as well... so these numbers are likely all larger than what is actual. I'd assume that your bigger rotors are more adept at dispersing heat, and thus fade is probably much less. How is the pedal feel?

Have experienced zero fade so far and have run the hell out of them, finally got the rotors to change colors on a mountain run too. The larger rotors and more ventilation between each face of the rotor help, plus the caliper itself is nearly twice as big and aluminum thus absorbing and dispering a majority of the heat...2 pistons on each side help too.

The pedal is perfect, don't even have to change the proportioning valve....wasn't too sure about it at first but once the rotors were bedded in it was fine. Been told a few times i will need to get a master cylinder brace soon...that much braking force will cause it to move and twist.

Good job on the DIY. I'm very impressed.
