Staging with Bump Box.

[Bill Baer]

It's illegal the Nhra &Ihra rule books prohibit any method of staging the car beyond visual use of the tracks equipment.
But if ya want to be a cheating bastard and risk possibly being banned for life go ahead. Davis will also sell you a nifty traction control device (also illegal) or google matty box cause if your going to cheat you may as well go first class!
