should also note, his car is the 'roadster' which is heavier. we ran several times, and i pulled every time.
car and driver has 13.0 for the sl55amg roadster. we all know the SRT can beat that.

don't forget, cold, crappy stock tires can make a big difference. his car is totally stock, and spun hard through first 2 gears. this was not on the track.
