There's a couple of guy's at the track that play the tire pressure game, one runs one front tire so low the starting line guy has backed him off. He claims he can leave as the 3 yellow comes on . I've watched , he does, he also red lights a lot. Another uses his tire pressure pounds to rpm launch 26 pounds =2600 rpm etc. . Just one mans theory but he wins a lot. Go figure. I just run 35 psi, pull the wheels out of the light on launch and red light.

it's ok to butt heads, just don't do it with a butthead
