    Camber What Is It And How Can It Make You Faster

    Camber is the angle at which the wheel and tire stand relative to the road – assuming it is perfectly flat. The easiest way to envision what camber looks like is to view the wheel and tire head on. When stationary the tire maintains a static camber angle whereas when the car is cornering due to body roll the contact patch is reduced.
