As you can see the specs are wide ranging as in most all cars and can be considerably off and still considered properly aligned but anybody into racing knows that is just not acceptable in the least.
-1.9 in the rear is probably a pretty good setting but this car has -.4 and 1.8, way off of optimal.
I will probably want to be around -2.0 to -2.5, not sure yet, wish it was adjustable!
I want to either have shims machined to correct and increase rear camber or I will cut and reweld and fortify the rear twist beam hub carrier mounting point, prefer shims.
If I use shims I know about the ABS sensor, it would be pretty easy to remove a little off the face of it so it sits in far enough to read correctly.
