I see Uzzi's Limerock Park is listed here.
After sometime I've returned to the ALMS cars and thinking of Limerock I set about the normal layout only to remember there was a problem with the ai going down the hill out of turn six. There was an aiw fix posted on the rfactor forum sometime back. Unfortunately, it's no longer available.
Does somebody have the AIW file in question? If so. Could you please share.
