all aid off except stabily on. It is easy with that using racing soft tyres that u'll never consume the only problem is the fuel so i used this strategy: 1 pit stop every 30 laps that consumes about 80-82% of the max fuel capacity so u fill the max fuel and go, don't worry for the time u lose in pit lane coz in 30 laps u can take 3 laps of advantage on the 2nd and late in the race this gap will increase, at 180th laps u will made the last stop and just fill about 60% and this is it. If u don't have the FGT try a Minolta Toyota fully tuned is also very good. PS sry for bad English
