New tire wear model was added so driving tires on the wrong surface ruins them Fast.
Get a Audi R8 race car. ( From OCD)
Max the mods on R8 set up. (Yes stage 3 turbo. engine run in) Max the aero for max grip round corners. (Its going to rain) lower the power limiter up till you hit <699pp then move up slowly till you hit 700pp. Dont change any thing else on the car.
Start in R:H.
Pit lap after lap 2 to Rain:Inters
Pit lap after lap 8 to new set of Rain:Inters (29-33% rain is not good for Slicks and bobs).
To be extra carefull PACE down as soon as you end the second part of mulsanne straight you dont want to end up in the sand trap in Mulsanne.
If your B-spec driver is to low he will not be winning the others are throwing the race away due to their random Driver AI. Every time you leave the event to go to GT HOME you randomise the car line up the next time you enter.
