This is the Bilstein setup I bought for a k or so with the front splitter Iove. It has the rear diffuser as well. Now I sm DYING for Edelbrock to send. My installer is sure to call me whrn a gisnt crate ends up in his office. My neighbor wanted me to buy an AMG that only needs a water pump. Knowing MBZ its part is $550 and cost $6,000,000 for labor. Oh...2010 with bad water and 174k. I think I will keep my Chevy with 5,420 miles.
