Took the Duster down the 1/8 mile for the first time and ran great (6.36 @107) But at the top end when I apply the brakes the whole car vibrates violent! I want to check the rotors for runout but these are brand new lightweight Wilwoods. Has anyone else had any pulsation troubles with these brakes? When the car slows down the brakes work great, it is just after i cross the finish and start to brake. ???
