Anyone got any recommendations for tyre pressure for 21" wheels on track? I know air / track temp can affect it but just looking for a starting point other than the standard pressures.
No experience on the RS6, but generally a good starting point is take out 15-20%, do 5 or 6 laps and then check, repeat. if a small track you may find one side gets a lot hotter than the other so you may need to drop one side more, i.e. brands hatch I always had to have less in the drivers side.
