I have come across this problem recently. I have installed some new rims, and a few suspension parts. Although I had an alighnent and my tires were balanced. I think my rotors were warped at the last event due to heavy braking. I am installing four new rotors, pads and ATE fluid this weekend so I will let you all know.
