We were the only car on street tires (Pirelli P Zero's).
Our 20"/19" show car combo worked great for the photo shoot and the video.
But when it came time to race Hoosier road race slicks have a slight advantage in the 700 hp range (understatement of the decade).
We played a Golden Girls DVD for Grandmom on my 15" airbag screen..
The USCC Video is now available, watch it and you will see us spinning our tires through 4th gear at 15 psi on the drag strip, I didn't even attempt high boost or Nitrous.
I was in and out feathering the gas trying (more like begging) the car to hookup.
I played the same game on the road course after every turn.
0.97 g's on the skidpad isn't bad for 20" wheels though.
671 rwHp 654 rwtq through a 3" cat, you can see the nitrous in the torque #'s.
