Not that this makes a lot of difference, but if you go back and read my post i stated that it doesn't always make the car look different, but sometimes it does. What I was saying is the chassis swap changes the dimensions in the cars specs. If U load a Mini in your 1st 2 slots, and put an F094 chassis on one of them, then go into the garage to view the cars, and open the car specs screen, U will see that the 2 cars have different weight, height, length, and wheelbase. I was mistaken about the front and rear track, but that's all I was saying.
