I'm aware.
Yup....I did not see the sense in it. I did however get the track package.
The R deletes the rear seat, air conditioner, electronics and radio. I happen to like all that stuff. It comes with the cool ass carbon fiber wheels that have the better track tires and they are size bigger (305 in the front and 315 in the rears).
Carbon fiber wheels are not well suited for everyday driving on the streets. And the bigger and better tires can always be easily mounted on the current rims if I really feel the need.
A few other little things, but in reality, the track package upgrade was the way to go for me.
