for the gears:
start rFactor, go to track & garage
Gear1Setting= 14.592
Gear2Setting= 11.905
Gear3Setting= 10.170
Gear4Setting= 9.004
Gear5Setting= 7.910
Gear6Setting= 7.316
Gear7Setting= 6.753
What I'm curious is , what are the true gears that the cars use at each track, is their an official list to real life?
