The past few days, I've been wondering about the grip thing with the modded wheels; my setups done on those cars don't always work well for the default cars and I've been suspecting that something was up.
So much to still learn about this sim...thanks!
- edit - question, then...
this mod's description states that 'This is a visual mod only, does not affect the performance of Cortina, though it looks somewhat faster'; this is not true then, and the mod is affecting the grip after all?
