Best ifs kit? rms, hdk, gt suspension, or magnum force?

Also, don't you always want the lower pivot points level, because if you're changing that angle, you effectively change weather or not you have camber gain during body roll

IMO....not necessarily. Ideally, I would prefer a little downward (out from in) angle.

Using the factory UCA attaching points, frame rails, and our motor location pigeon holes what we can do.
