my BDR car #260 does it, the "bump shake". everything on the front looks good. I did find that I needed to make special stepped bushing to hold my strut shocks in the proper location. The flat washer thing did not work! Posted this fix on Backdraftboys forum...but the forum is gone now. Mine is now set up with standard manual rack and mounts, 1 1/2* camber, 15" Cooper Cobra tires at 22 psi. I was thinking...it's just the why the car is designed and built? Sound like we have BDR car that don't have the shake. Humm
