I've got a new one, placing 2nd in Pacific Gateway Reverse race. 20 laps, two Nissan GT-Rs, NSXs, and Supras (the JGTC ones), on hard difficulty, no driving aids or anything.
Ran some pretty poor laps at the beginning, halfway point I was a good 30 seconds behind the leading GT-R, finally got the Supra figured out and ran each lap a good .200 of a second faster than the last until I set the fastest lap of the race with 2 to go. The last few laps was a Villeneuve/Arnoux esque battle with an NSX, took the position on the second to last corner and 'won' by .024 of a second.
