Whoa, Selnor, GT not being about gaining a tenth of second, being casual? Sure, if you play it with all the driving aids and have a car with more BHP and less weight than the competition.
Do me a favour, and play the game without TCS, ASM, minimal LSD and AYC off, go to Le-Mans 24 H, taking with you a Toyota Minolta-C 88 which will have the same amount of BHP as the cars racing in that endurance, but with at least more 70-100 kgs, Using Racing Super-Hard Composite tires.
You'll be sweating to gain even a few hundred of a second per lap, just to be able to leave in front of the competition in every pit-stop that you make, since the A.I is superb at mantaining a lower degree of fuel consumption and tire wear than you, pitting only one/two laps after you have pitted.
