I have the BAT handling kit, and I am very pleased with it's performance. Much stiffer, but not so much that it will rattle your fillings out. I personally chose not to go lower for two reasons: 1) I can barely get a jack under my car now (have to drive it up on 2 X 4's), and 2) no worries about camber adjustment. I have not experienced any abnormal tire wear.
