Tony, can you give me an idea of how to lower the rear slightly by modding the auto ride links? I may go to springs in the future but right now I will just be doing sways. The sways you have on the site are about a $100 difference in price, is there a big difference in one or the other over factory? Mine is a 2007 LTZ, sorry to high jack I can't do a pm yet. Thanks, Mark
