I ran a 115in wb slingshot with 280bhp and 4sp. With the manual box, the car will wheelstand no problem, so if this is your thing, have a robust front end end that wont bend on landing. IF you want to stop it wheelstanding get as much weight forward as you can, battery, fuel, weightbars, filled tube axle. If you run a wheelie bar it needs to be long and flexible or sprung so that its progressive in its action. A fixed bar on a manual car will unload the tryes as you hit the bar hard on the launch. If you don't want it to wheelstand at all run a tall gear.
