24 hour Le Mans and Nürburgring - lap times?

[MuRRe]

Me and 2 or more friends of mine will soon be doing 24 hour Nürburgring (im 100.000 exp from lvl 40).
What kind of lap times do you need to win or maybe easier, how many laps do you need (for both Le Mans and Nürburgring)?

EDIT: Damn, wrong part of the forum.
Mod please move this to Q&A.
