Ferrari does use wind tunnels you know. Most likely all that body kit does in terms of performance, is upset the aero balance of the car. And those rims are about as far from performance rims as it gets. They probably weigh a ton. If you have the cash for that car you should pick up something like the BBS forged magnesium RE's.
