More expensive than Carl's setup, but more adjustability too. I haven't had a chance to do any serious driving to test the setup on my coupe, but I am super pleased with the looks; my coupe is perfectly "stanced" now. Immediate upgrade to the stock system and maybe a skosh more firm than Carl's. Will probably allow you to run wider wheels as the entire configuration is smaller in diameter than stock (front); I am running 16in Alpinas (fenders rolled).
