Well I bit the bullet and got a T5M from here. Showed up a couple days ago so not enough time to get it ready for tonight but will be ready maybe for next Friday nights race (or at least a practice day).
So I will run stock buggy and then we only do mod stadium truck.
I like the idea of doing two classes with a 17.5 by running mod but I am not anywhere close to expert stock to make the leap to try to play in the mod class.
