A note to Steve. Next time you mash the throttle in 4th gear in a GT2, could you please describe what is going on? Two friends and I were sitting around the computer watching this video and wondered what had just happened. Throw out a few numbers maybe? I know you aren't as verbose as Harris (been reading the mag front to back here in the US for over a decade), but when we have no sense of speed we need that sort of detail.
Anyway...we could only assume something like 50 - 100+ mph went by rather quickly.
Cheers
