You didnt use Nitrous on that 50 sec time, did ya?
Nonetheless, even with using Nitrous on those long Midfield str8ts, its still good time.
Will give your setup a try tonight.
Only three have beaten your time, and they were all using the Formula GT car. You are almost a full second faster than the fastest Le Mans car time posted.
