I don't do 'supers', but if i were..., it would be a modded item - Zent body on Insurgent or Hauler characteristics, Sultan RS traction and RPM mods that translate into Mach 6 territory at the redline.
Yes i am mad, and i did test the theory out and it definately suited my sick idea of driving the Shopping Trolley with Thrust 2 performance but with enough momentum and moving mass to obliterate a Rhino or just about anything else it hit
Or for complete overkill, add Nitro .... and see me get hated by everyone in the lobby who's not already got a hit out on me
If it had to look like a street sleeper, then substitute Zent body for a News liveried Rumpo shell.
