simply doing properly tuned coil overs with hydraulic bump stops will give you the go fast set up. I was hitting 60 at the hammers a couple years ago and stopped there because I didn't have a top doors or helmet on and if something go wrong at speed it typically goes really wrong. The only thing that I really noticed then was I needed more up travel because as a crawler set up with long travel shocks I only had 4" of up travel. I should have that worked out now with my current build and have moved to 7" of up travel on the front and rear with 18" 3" triple bypass and 2.5" coil overs on each corner while keeping the lift in the 4.5"-5" range.

 

Mine was done at Evo in Cali.

No argument there. Lots of ways to skin a cat. Just depends on how much time, money, knowledge, mechanical ability, patience, etc., that one has to put it all together. Finding a kit that you can put on out of the box that will run exceptionally with a little bit of fine tuning, if any, is why they get that price. Some people want to be able to take it somewhere, have it done, and run it without any further concerns.

I agree with the compression side of things as I'm sitting on 5-6", but I'm also on 40's and somewhat tall, so cranking it up isn't something I'm looking to do as it has done everything I've asked of it, going fast or crawling, so I can't complain.
