I went back and played with the tvr a bit and found cornering speed with a really light car, so I think your right that it has odd grip values. seems like it's grip was set up for min weight and it is not scaling correctly when ballast or weight is added to the car. but the car was so under powered I couldn't manage any decent lap times. I think someone at PD has a thing for Lotus as they all handle really well. -or- one of the more experienced programmers drew the Lotus card and that's why they are all good.
