Wayne and Erik put the bushing above the bracket... That modifies the suspension geometry. You can do that if you use a spacer under the other leg, it is about 1/4 thick. If you don't use a spacer when you tighten it you will distort the aluminum bushing housing, not a good thing to do to aluminum, when aluminum fails it cracks, a dangerous condition IMHO and Tony's as well.

They did a bunch of work to develop a high performance design, I'll make mine correct. Only the early cars will have the issue, I'm not aware of what chassis number will start getting the modified bracket, mine is #17
