Well I have the rustys 3" full leaves. I sit around 4-4.5 I went wheeling yesterday with some buddies (ill post my pics thursday) Now I had some crazy flex, one of the guys was actually worried my coil could go unseated, I have the rustys adjustable LCAs. I didnt believe him so i went out and wiggled them and they were pretty damn movable. I think the only think stopping me from more flex was my fenders. Whats crazy is my brake lines are in the stock location. Now I am sure i am way off but it was still crazy none the less.
