If your car is a CR, otherwise I would say its non BTM.

 

My reading of the rules says that it does include the CR aero even on a non CR model. Remember these non points based classes really try to simplify things. You either have OEM aero or you don't.

 

I have a dented and dinged up OEM hardtop. But I plan to take the Aero points. I don't have much choice I dont' think i can get to the non-aero HP number. I'm planning on running Michelin Blues and taking the huge hit for Slicks as I don't think I can get to the hP number for A7's.

 

whats everyones preference between a roll bar (like a hard dog) and a roll cage (say welded in)?? would love to hear from people with experience with both!!
