class for mustang (SCCA T4)

Postby blacksheep-1 » Sun May 24, 2020 2:37 pm

So I dragged this home the other day. it's a legit SCCA T4 class road racer. which basically means it's an almost stock V6 drivetrain, with Ford Performance suspension (no coil overs allowed) no interior, with a cage.
it would vaguely fall into the GS class.
so..open modified? that would mean ANY street tire
or..could it be run in another class with a 140 TWR tire?

Would be M2 except for no interior. So, M0. If you want to run a TW less than 140, then R1.

Push Harder - Drive as close to the limit of your tires as possible.
Suck Less - Drive something resembling a proper racing line.
