Theres a difference between Pro Street and Pro Stock here....
The pro street kits are going to have a standard street engine, the Pro Stock will have the race motors with 5 speed trannys, tube frame, etc...
The pro stock kits will have the wheels (weld pro stars) I'm guessing you want along with the tires...
