Today, I took my 330d for a spin on the ring, I have the blue 4 piston M-sport brakes and if these are the same brakes as on the new M3/4, start saving for the CCB brakes
... After 3-4km the fading was just rediculous, talk about wasted money
...and pedal travel almost to the metal... Even the E92M3 managed a lap with no major fading...
On an other note, saw an i8 in the wild there and it looks stunning!!
