?Suspension Question?

No.

Also, typically when you're adding both upper and lower aftermarket control you're introducing additonal bind to an already bindy suspension.

You'll be fine in a straight line, especially being to tune the pinion angle with the uppers but once you get into a hard corner thats a whole different story.

If you want to get some great handling forget the springs / struts / shocks and get coil over suspension. From there, get a panhard bar / torque arm and remove your quad shocks and upper control arms.

3 link suspension is arguably better then the 4. Although the Steeda 5 isn't bad either.
