What did you set yours to? Right now mine are stiff but not spine-crushingly so. They still translate bumps into the cabin but they aren't a nuisance, and definitely a tad more comfortable than the OE shocks/struts I replaced.

I don't recall offhand and would have to check the fronts. I did loosen them up a couple of notches recently and it helped. I with the rears could be set easier...Quote:

Hard shutter in the steering wheel yesterday at Road America. First session was good, second session I made it 2 laps before the issue started, right after a really hard brake down from about 150-60ish.
I was on Cool Carbons which aren't "track pads" but have similar specs as a Hawk HP+ pad (hybrid) from what I researched so I doubt I cooked them. Brakes have never done that before. System was just bled - would some air in the system possibly cause that? Stuck piston? The Brembos were rebuilt this April.
Or could this be more suspension related?
Went out again for 3rd session and same thing so I hung it up for the day and drove home. Car was fine on the highway.
Thanks
What about the rotors?
Feel any vibration in the brake pedal?
A bit, not as bad as in the wheel, but the rotors looked ok upon inspection and if they were warped that'd be fucked up cuz theyre new BMW ZCP ones from April/May. Those aren't gonna warp that quickly/easily. I should probably have them turned anyway just in case but somehow I don't think that's the issue or else I'd really feel it at highway speeds which I don't.

You may want to invest in some race pads for that kind of speed.
Did you have your bushings inspected? Does it happen at all stages of the brake pedal (light pressure, medium, and heavy pressures) or just a certain stage? Does turning while braking make a difference in the shuddering?
It is not recommended to "turn" BMW rotors, BTW. I'm not sure of the exact science behind it but I've seen/heard it from numerous sources.
If I had to take a guess, I'd say there's uneven pad deposits on one or both rotors. Did you properly bed them in prior to going to the track?
Yeah I've heard guys had decent days on track with them. This happened 2nd session out. I had DT60s but only front so I was advised to not use them.Quote:

This morning they felt a little weak. We looked for pad deposits but didn't see much of anything and instructor did some hot laps to try and see if they could clear them. I bedded the pads when new. If they weren't then, they are now right? Lol
