Guys and gals, need some hints here. Two times my alignment (camber and I'd guess toe) have gone whacky on me with no changes made by hand. Tonight keith and I note that it looks like the front left wheel has been knocked to less than 1 degree negative camber. What torque are you folks using on these eccentrics?

FWIW, the car is a 87 944-S and the mileage it gets is 50% track and 50% street (little errands and to and from the track).

TIA

Make sure that you haven't damaged the washers with "D" shaped holes in them, if so, replace them.
