Me and my dad just opted to upgrade the shocks/springs/bushings while keeping the same control arms and steering tie rods. We bought the Street Bandit Handling Kit from NPD. I don't remember what page it's on in this years catalog, but it was $300 or $400, I forget which, and it comes with new lowering 600lb front springs, high performance rear leaf springs, front 1" sway bar, rear 3/4" sway bar, all mounting hardware, rear lowering shackles and, oh yeah, gas-a-just shocks all around, and I forget what else. Then we bought a bushings kit that was on the page directly across from it, and it said, "Perfect compliment for Street Bandit Handling Kit", so we bought it ($300, I think) but it came with all the bushings for all the suspension. We haven't put it in yet, but it looks like a pretty darn good kit. I'll let you know how it works once it's in (although, that might be a while, lol). Good luck with your upgrades!
