1. I have no doubt that Sam's car could be at or close to a 9 sec. pass with a 60' such as yours, but, the stock suspension design doesn't lend itself to that.
2. There's nothing to fix on that car. It's doing fine with it's current design.
3. I'd rather have a 10 sec. @ 130 car (That can outhandle most other cars on the road) than to have a 9 sec. @ 130 one, that can only do one thing. But, to each his own.
4. It's panties.
You chose yours. He chose his. Quit critisizing people everytime they don't run a near perfect time in their vehicle. Practicing is part of the game. Sheesh.
