Someone I know used to have a fast RST. Was about 300bhp at the time of this video. Looks like it goes OK, I never got a passenger ride in it though.

Does look like it truly lights the wheels up in third at 70mph though, and the roads look totally dry.
I also think it looks like it reaches 6300rpm in fifth, what do you think?
