that wouldn't make sence to have a cage rule for the whole ah class.some guys don't have the funds to go 8.50's in good air or ever.if so there would be alot of cars going back to the chassis shop.that would be cool if they did let the ah cars go beat up on the vettes if they can't run in ah because of the spec change.i do agree with the chute on the 150 mph cars.plus it looks cool on those cars. ,but what do i know i just paint stuff.
