The top gear test track. It is probably longer then 2 mins depending on what car you use but I believe it is a good track to get a good tune.
Special Stage Route 5 for mine, nice long straight, some medium speed turns, a tight hairpin, kerbs to unweight off at the apexes and you sure know about it if you overcook it into a wall. Nice length too.
I think the Nordshleife is the best, turns, tight corners, and several straightaways.
