another update.... in the damage file for the cars I found AeroMin which appears to be the amount of contact that is required to affect the aero for the car, so I lowered that. It was higher than even having the front of the car coming off, so in my mind that means even if the front end comes off the aero isn't affected. Another thing I saw is Radiator Cover Instance which if this part comes off the engine cools but aero is affected...The part was RadCover. When i checked the parts list in the damage file there is no RadCover, but FWING which is the bumper and hood from what I see in the races. So I changed the part to FWING.
I know nothing about the files...just doing trial and error hoping that someone with knowledge has an answer. The cars still are not pitting if they lose their front end or rear wing though, but they are repairing damage when they make their normal pit stops.
