Reply to "Lets talk shocks..."

Shock absorbers have more of an effect on ride quality than springs do. High quality shock absorbers do an excellent job of damping the suspension and controlling high spring rates.

I have aluminum bodied Koni gas shocks (from Pantera East) and can attest to the fact that the ride is very comfortable with them. When I put 18" wheels on the rear of my Pantera, I developed a minor rubbing problem under full suspension compression. In an effort to reduce suspension travel under compression, I removed the 475 lb springs I had been using and installed 700 lb springs. Much to my surprise, I could barely tell the difference, from a ride quality perspective. As per Dennis Quella's advice, I also installed an extra set of bump rubbers in the shocks, which is what I believe resolved my rubbing issue.

My Pantera, with Konis and 475 lb (front)/700 lb (rear) springs, has a more comfortable ride than my bone stock, daily driver, Porsche 997S!

That being said, if I were doing it all over, I'd either follow Julian's advice and try double adjustable QA1's or I'd go with Ridetech double adjustables.
