Plywood courtesy of Lowe's. Shrader kit can't hold more than a couple bags of groceries by itself. It doesn't match the interior carpet, it's darker, but intentionally - it matches the rear dash carpet perfectly. It blends together out of sight when you see it in the rear view mirror.
Made a friend.
S550s have been popping up more and more around me. It was nice to compare my ride height to the stock ride height directly. I definitely am in favor of a 1" drop on these cars.

For example, Tire Rack will tell you the wheels fit even if they need new lug nuts; however, if you need new lug nuts Tire Rack will just include them for free.
