There is a little error in the skin mapping on the Left side. If I just paint a color its hidden but when drawing shapes around it with different colors it becomes noticeable
A good car in terms of modeling and design. But the balance is not good.
Unstable on the track, difficult to control. I thought the balance issue was due to the frame, so I examined the frame of the car and modified the frame a bit. I took the weight balance lower than before. I hope it works for you.
