seaball-you know both of us are obsessed with testing....but I know from first hand experience that sometimes a car has all the right looking go fast gear-but for some reason-on carpet-just wnt pull those last 0.2 or 0.3 seconds-even on the most perfect of perfect laps.
Its weird. I think its a combination of more testing needed by lots of drivers and also maybe inherent problems in driveline that only show up in high bite conditions. LIke yu said-cars good untill grip comes up and then driveline apperas to bind-up and car wont accelerate anymore.
