you'll need to call sfi to order a 25.5 book, lots of information you will need in there.

What organization will you be racing with NMCA, MDRA, PSCA, ORSCA. Each organization has several classes and rules

Thanks for the info on SFI.

are all the classes for racing f-bodies stock style suspension? I was considering changing the suspension to ladder bars..But if everyone is running stockstyle, then I won't change it.

it all depends on what organization and class you want to run....

If you are talking about LSX shootout Rules i wouldn't base my build on it since it's unsure if Gm will ever sponsor another one.

Some classes make you run stock suspension, other have no limits to modifications.

Yeah still have them.

the wheels have a 5.5" BS the axle is narrowed 3.5" per side and a Wolfe mini tub and offset Spacers For the Lower Control arms. A weekends worth of work.

they will also work on a stock axle with a 7.5BS wheel with some trimming of the bumper, they will just not be tucked up into the fender like that.
