Automobiles list among the most complex forms of engineering because they use a combination of many different types of technology, so it is quite understandable how bad info can float to the surface. Our friends at Engineering Explained could help you out with finding out the facts about five modifications on your car’s performance that actually may not be such a good idea.

1. Negative Camber

This is probably one of our favorites, since even after people are presented with the facts they would deny it for eternity. The following figure is from the book Tune To Win written by Carroll Smith.

The coefficient of friction between a tire and the ground is perhaps most important characteristic of a tire. The higher the coefficient of friction is, the more grip a tire has. As you can see in the picture bellow, peak grip occurs as the result of about -1.0 to -2.0 degrees of negative camber. This number can change depending on the specific tire and the lateral load it’s experiencing.

Besides a reduced contact patch and as the result, less grip, heavy negative camber will result in uneven tire wear and its uneven heating on the track too.
