Mike, I saw Joe Amato at (then) Firebird making a bunch of runs with ground effects on the car. He tried small wings, etc. but the scariest was a run with NO wing. Car actually hooked up, didn't smoke the tires, ran a low 5 (which amazed us), but lets just say it was a scary run. It was the last time they did that. Also, NHRA had (has?) a rule that says the wing had to be set at whatever angel & could not be manipulated by the driver or electronically as the car made the run. Same w/ the body of the car, could not be lowered as the car made the run. Not sure how this would apply to P/M. I like the idea of a solid mounted rear end (altho I'm told the shocks can be set to mimic a solid mount) and wish they would add, say, 12" to the wheelbase.
