Grand Am Cup

[FrankBarba]

i was checking some of the rules & regs for grand am cup racing.
the rules state no cat's....why would this be? are they afraid that cars will catch on fire if the cats get too hot?

Yes, hemi, but dogs are an acceptable upgrade. I wonder how the Competition Coupe will get approved in Grand Am? Two things on the new CC are definitely not allowed and they are the cage bars extending forward to the engine compartment and the cockpit adjustable sway bar is also not allowed. Wonder how the CC is gonna get approved?
