Odd Brake Pedal
I was at the track last weekend and it was only my 2nd day in the m3 (before I had a mini). Every once in a while the pedal would take an abrupt dive but the front tires griped (squealed), car still slowed down and the ABS was definitely on.
I have high temp fluid and street/track pads (they are stoptech not sure what part number). Anyway the pads were still fine for sure and I don't think I had air because the pedal would come back fine on the next stop and wouldn't feel squishy.
Was I just not getting to the ABS on most of my stops? (my tires stink and the amount of noise coming out of them may have kept me from going all out on them). Is the ABS causing the drop? (this seems incredibly unlikely)
Any thoughts appreciated.
P.S. below is the video of my best lap which still has lots of room for improvement... you here the clunk sometimes in the turns? I think I have the sub-frame problem any thoughts there?
