On some tracks there is concern that the AI are running far too much wing
(e.g. Spa), so you end up blasting past them down the straights.
It is now possible to edit the default AI setups to more realistic levels
for the track. This ensures that the optimum setup for you matches the AI to
ensure close racing throughout.
Check out the High Gear forums for this tweak and more
