If you truly enjoy the art of motoring and plan on a track day here and there, then I think the $4K is worth it. If the car is merely a means of conveyance or a part of your image, then don't. Simple.
A quick rundown of what the Comp Package entails:
- More aggressive wheel/tire combo.
- Retuned suspension.
- Enhanced steering.
- Addidtional DSC setting (M Track Mode).
- Better brakes.
- Optional SMG gearbox or conventional manual...you choose.
- Alcantara steering wheel.
- Aluminum interior trim.
- Optional Interlagos Blue exterior color.
"...I mean, granted you get nicer brakes but aside from that, there's nothing..."
I count a total of 8 "nothings" in addition to the brakes, so I disagree with your statement.
