Now that I know the track a little better I'm going to go back and try the early models again and see if I can improve. My first series of attempts were fraught with invalidated laps mainly while I learned the best lines through Piff-Paff and the other chicane that's not really a chicane.
I have done all the stock cars I could find. Being my first time without SRF and rarely using this track the lower PP cars probably suffered from that in the lap times (~6 laps per car with at least two valid laps):
NSX '90…………………………………………………….. 2:34.837……. 108,318th

NSX '93……………………………………………………… 2:32.561
NSX '95……………………………………………………… 2:32.169

I am now tuning the Type R'02. I am a total noob at tuning so it is just for fun but if I can squeeze into the top 1000 I'd be quite happy. Currently 2130th with a 2:21.705.
