Subscribing to this thread...
I've done 3 track events so far with the M2C bone stock, aside from Castrol SRF brake fluid. The car is great for my intermediate experience level and works extremely well except for one issue. Under hard braking, near ABS threshold, from 100+ MPH, I get an unsettling shudder in the car. I don't think its pads or rotors since I don't feel it in the steering wheel. It helps to ease into the braking or stay shy of threshold levels. A friend noticed that in his M2C as well.
Some have suggested track pads, others adjusting rear toe.
Thoughts?
EDIT I posted in another thread but here's the start of a track session at CMP chasing Vettes.

I think you can see the shudder at turn 8 braking at 1:00, 2:55, and 4:50 in the video.
