Yeah, they are definitely meant for show and cruising, but not for improved quickness. There just aren't too many options that look good and fit right on these cars. There are some nice 2 and 3 piece forged wheels, but they cost nearly as much as a Crossfire Limited! I went for improved handling/comfort/style over speed. I just hope the rear end, bearings, and transmission handle the extra rolling mass over a long period of time. We'll see. Did I say they were HEAVY?
