Excellent 1st race guys really enjoyed it!?
Welcome Mason, glad you're enjoying the game.
1. Does GTR2 and/or Motec give you data on tyre wear!?
Don't think Motec gives tyre wear info. It is available in-game, but annoyingly only when you pit. I've always wanted to be able to check wear at the end of a race, but if you pit after the checkered flag it dumps you back to the lobby.
Fortunately, it's possible to check the wear using the PDMonitor utility (anyone have a link to this?). The wear values go up to 60, but at 30 it's seriously worn and you'll start losing heaps of time.
2. Once you feel you have a 95% correct setup set as symetrical , are you guys then doing any minor non symetrical changes!?
Yes, lots of drivers use slightly non-symmetrical setups, especially tyre pressures.
