Make sure you put the side links on so the small screws don't hit anything, and have the larger ballcup on the rear pod end so it can move freely without hitting the chassis, i suggest also putting your electronics back next to the links if you can fit them there.
As for the side springs you want just enough tension for the rear pod to center, and please make sure everything is symmetrical left to right..it just erks me when stuff isn't..lol
