You get a titanium exhaust, plastic/CF trunk, Mini battery and you have a lot of weight out the back of the car.
Considering that the car is already designed to carry back seat passengers and a trunk load, it's not too critical for street use. If setting up for the track, adjustments might need to be made, but you're making those anyhow (alignment, tire pressures, etc.).
