Caster setting

That's exactly what Peter Bergman explained to me when I bought the SPC arms from him. My car does sit a bit higher and lifts quite a bit on launch (pics suggest about 4" of lift) and down the track. But c'mon, there's cars that are a LOT faster than mine that hold the front end up and don't have this stability issue. So I am counting on the UCA's to give me some caster and address the stability concern.

One thing a higher ride height setting does do is cause more toe change when the wheels drop down. I've used the methods described in the Mopar Performance Chassis manual to measure this. The tie rod end "looks" longer and adds toe-in when the wheels drop. So it's all a balance that I clearly have wrong and will get after when I install these arms and set up the alignment.
Do you work at a shop with an alignment rack?
