Have you tried the 20's or 18's? I felt there was to much understeer in my Hyper so I switched to 18's. It went form turning wide, to spinning out if I cut the wheel to hard. Its a HUGE difference. Just make sure you use red loctite on those bottom knuckle bushing screws.
Not yet. I've read a bunch of stuff about suspension alignments recently, so it's on my list of things to try though.
