The last 3 laps I had no 'pushable' grip left, so just decided to settle for 2nd. Yeah I did lift on the occasions I felt I gained significant amounts of time, more often than not I actually lost time by running wide + compromising the next corner.
Will be interesting over 2 hours as I got a feeling that R8 will make 1 less stop than everyone else, and its fast anyway! If the average stop costs you say 30 seconds, its only about 0.5 per lap that we need to gain to make up the time for the extra stop. I feel the Viper can do it, as its proving one of the fastest on most tracks, not so sure about the 458, its close, but I think it's lacking about .2 a lap. If the stop takes 45 seconds then that bumps it up to .750 a lap, and that is a little too much to gain I think. But, you could be losing 1.5+ a lap at the end of your stints, so who knows only time (or Iwin) will tell us
