Raced this event last night in the Audi but not the TT, I think it's an R4 or something, can't remember. It needed an oil change, I added my weight as a ballast and drove with no aides and still won by 2 seconds. Same for all the other cars I've tried it with, the BMW, the Merc.....
Maybe it'd be more fun with a power limiter applied because this event is not difficult but still fun.
