I got a friend of mine who has an 05 cobalt ss. Now apparently when he races it. He doesn't use the clutch to shift. Nor does he let go of the accelerator. He just rams it into the next gear. I don't hear any grinding or anything at all, gotta say, pretty crazy. I've researched it a bit and youtubed some videos and there seems to be some a debate on it so my question to you guys is: Is this insanity or there some actual merit to this?
