Danica question on cars?

There is a huge difference. The weight of the cars is VERY different. The speed is very different. The degree of power and downforce are different. Anyway, she isn't the first person to attempt to make this change. Several before her have failed. Don't you remember Cole Trickles's crew chief in Days of Thunder: "When you were driving open wheel cars, the cars weighed half as much and the tires were twice as wide. Now the car weighs twice as much and the tires are half as wide, and you're burnin' em up!"
