Great job so far! I have a few weeks for you I know a couple will come with time ( damage modeling and sounds). But the big thing that is off is the way the winged sprints react to the downforce, the cars are rolling over the right rear tire, for the wingless cars this is fine. The winged cars however squat on the left rear at speed to keep the car planted to the track. This roll to the right is causing unusual drifting sideways on corner exit and at times flipping over on entry.
