I had a Sears installer refuse to mount my tire rack order for my MS. He said he didn't want to risk it because the car is carbon fiber. I told him he's thinking of a different car, this one isn't CF. Still, wouldn't do it (I'm glad now because he's probably an idiot). So I b*&^d at tire rack and made him deliver the tires to someone else, who did it with no issues.
A side note, I pulled a wheel and tire off and put it back on after getting a flat and having a single tire replaced. First, the car is freaking heavy, and my 3 ton jack was creaking the whole time (Harbor Freight :/ ). Second, the wheel and tire is heavy. Third, the torque spec on the lugs is huge. Not a fun job.
