Q: What is camber?

Camber refers to the vertical angle of your wheels and tires relative to the ground. Positive camber is when the tops of the tires point away from the center of the vehicle.

Negative camber is when the tops of the tires point towards the center of the vehicle.

Zero camber is when your tires are flat on the ground.

You might be wondering, “Why would I want my tires to be anything but flat on the ground?”. From an efficiency standpoint and maximizing your tire life you would be correct you do want it to be flat on the ground however during dynamic driving and cornering your tire experiences a lot of deflection and what that means is the outside tires take a majority of the load of the car and especially the outside of the tire itself and through deflection you get more compression on the outer sidewall and you get lift on the inner sidewall. To compensate for that, you essentially add additional negative camber to ensure that you’re maximizing your over contact patch while cornering.
