When creating a car designs, I always complete one side of the car and mirror it after that to the others side. But its totally unequal and I have to adjust almost everything manually to its correct Position.
Why is that ?
I’m sure someone will be able to give you an accurate technical reason why. All I can say is painting in Forza has never been an exact science. There have always been issues/quirks/glitches, call them what you will, which go towards making the challenge of producing a good design exactly that… a challenge. I might be in the minority but I find them irritating & fun in equal measure.

ok thanks for the quick answer, i thought maybe i am doing something wrong.
Some cars don’t even align at all. Back on FM6 for me was the Mazda MX5 Cup, none of the sides aligned at all for me 
The quick answer is after you mirrored, highlight all and move as a group until it’s aligned… span a shape across the rear and align your side to it for example
