Thank you for this work. The car models are fantastic and easily merit 5 stars. The physics though do need improvement. These cars oversteer far too easily. They feel like they are set up to be drift cars instead of track focused sports cars.
I have driven the C6 Z06 in real life and can tell you that it does not oversteer at the mere hint of throttle. The thing has tons of grip. Yes, it can break the rear tires loose but you have to push to do it. Currently the Z06 and ZR1 oversteer in a turn at 3000 rpm with part throttle.... definitely unrealistic.
Perhaps the physics guy could look at how the RF2 versions are set up and make some adjustments to camber etc? These cars feel better in RF2 ... although they look better here.
thanks for your work. Please receive my feedback as constructive... I am sure the whole AC community values your effort and I certainly do.
