Anyone else playing this at the moment?

Well it's winding me up something rotten.

I've passed my A,B and C licences but am having trouble with the "S" licence,namely the PP700 Fuji F stage.  I'm consistently banging out 1:42s laps and cannot get 3rd place, let alone 1st! (3rd is considered a pass)
I've been on it for an hour each night and have tried various settings, suspension, brakes, downforce etc and am yet to find a happy medium. I'm close though 

I'm driving the Mine's R34 GT-R if it's any help..

Anyone got any tips?

I passed last night.. all I need to do now is earn another 50k and buy the F40 and a Ford GT to complete the "S" licence then build up my bank balance to buy the Ferrari F1 

I can't wait for the full version to come out.. I just hope the garage can be carried over.
