I currnetly have Hotchkis springs and Edel Ias in the front with a Belt tech drop in the rear it rides pretty smooth on decent roads but it can be rough depending on the roads. I had the Hotchkis springs in the back but it liked to have killed me just to rough... So im thinking of going with air ride to smooth things out when im just cruzing but will still handle well. The stock springs with the bell tech in the rear keeps bottoming out on the frame bumpers and they are really short so i gotta do something to cure the problem...
