NASCAR’s biggest problem is limiting what they can do to build faster cars. They banned the Dodge Hemi, the Ford SOHC engines in the late 60’s and then invented the restrictor plate to limit the Ford engines in the 80’s.
Anyone notice a pattern here? That’s right you don’t see them doing anything to Chevy/GM cars!
Smaller cars with limited engine sizes to equal boring races. If the drivers want to faster with the known risks then I say go for it...
Actually, wind tunnel testing showed that when cars exceed 200mph, they have a stronger tendency to go airborne when air gets underneath them.
This was proven again recently when NASCAR added the wings to the backs of the COT in the 2009 season. When these were used on super speedways and the cars got turned around at speed, the wings designed to hold the backs of the cars down suddenly became lifting devices that pulled the cars into the air.
See: Wild Crash! Carl Edwards goes airborne and into the fence just short of the finish line at Talladega
Remember the special rear window for the Chevy Monty Carlo in the late 80’s?
NASCAR has always favored GM.
