Just started the NASCAR series, currently I have a HUGE lead at Indy (10 sec.), I set the transmission at 224 mph. Hope I don't jinx it. Will update though.
EDIT: Well, heres how it went (I used TigJackson's setups):
Indy: won by 9 seconds, real easy here, just get out in front, pace up and get away, then maintain pace as soon as you get a sizeable lead
Grand Valley: Forgot to do the setup here, and well I screwed up, spun while in 3rd. Then quit.
High Speed Ring: same strategy as Indy, just don't spin out, as my driver kept skidding out of the last corner for what ever reason. And, spam "Maintain Pace", it helps.
Laguna Seca: once again same strategy as Indy, hower more sliding, as spam "Maintain Pace", again not to hard
Daytona, had trouble pulling away, int the first 10-12 laps, then I started used "Pace Up" in turns 2 and 4 and began pulling away, won by about 5.5 or 6 sec (didn't look to see exactly)
Won by 140 points, (got 400), will try Grand Valley again, but otherwise NO MORE!!!
