Car rides straight.
I had negative camber in the rear from day 1 after lowering. The tops of the tires tucked hard.
So I bought adjustable camber brackets for the rear. Turning the bolt slides the upper U shaped arm in and out.
Last alignment the guy said he pushed them out as far as they would go and it's close but not perfect but way better then without.
So just for my peace of mind I bought 8 new bolts and lock washers (35m long) and 16 washers
put 2 washers behind each bolt on the brackets - figured this would help kick the tops out more then I have all that room left in the adjustable bracket to kick it in if needed.
Maybe the tech didn't know I had adjustable brackets back there ?
The he cross caster blows my mind. No idea ?
