I really enjoy watching Rally. Some very talented drivers, no doubt. But, they are driving very light, short wheelbased cars, often on loose surfaces. Steve Kinser would eat their lunch. NASCAR is heavy, longer wheelbases on pavement with a LOT more carburated horsepower. F1 uses traction control, low COG and computer controled fuel. It's apples and oranges.
What I'd like to see is IROC move to different surfaces and tracks with cars to match. Now that would be interesting.
