There is no allowance for a carbon fiber Hood
. Only in SM does it say hoods can be replace. Honestly you'd probably only have problems if you went to a national event. If you were protested it would be pretty obvious to a tech that technically the car should be in a higher class. If you think about it thoses mods pratically don't give any advantage and nobody regionally cares. I'm just stating the fact that it is in the rulebook.
