the C&D test is very valid...
100-0 1/2 g stop
20 seconds
100-0 max g
20 seconds
100-0 max g

100-0 max g

100-0 max g
20 sec
repeat until failure

one cycle takes ~ 5(20) + 5 (5) ~ 125 sec, 2 minutes...
the 335i did not fail, but the warning light came on after 7 cycles!
35 100-0 stops in 14 minutes...
pedal travel increased 1.5 inch, the PCCB's ~0.75"
pedal force, 18 lbs to 23 lbs or so

the M3 brakes are much better and the tires larger...it would only perform better:
larger rotors
cross drilled
aluminum hats
floating
more mass

think about it

btw: the PCCB's performed no better than the std 997S brakes
