A method of changing gear so fast you would not belive. Employed by leaning forward alot, grabbing the gearlever and wrenching it back (in to 2nd or 4th) using not only your arms, but your whole body. Changes can be done in as little as 0.12 microseconds. Russ perfected its use, resulting in a "repairable" 307 HDi and a "she'll 'ave to go to the factory" golf 1.6 hireglen.
I was using my super special james change and it all went a bit glen!
