Belltech front end alignment kit options include new cam eccentrics or offset control arm bushings that both offer an increased range of adjustment (typically up to 2 degrees) above and beyond what is offered from the factory.After you install a Belltech lowering component, you should always check your vehicle's alignment. Once lowered, a wheel's camber may become "increasingly negative," meaning that the top of the tire is angled inward. While some "negative" camber aids in improving traction and road adhesion, too much can result in peculiar handling and accelerated tire wear. These alignment kits assist in adjusting a vehicle's camber back to factory specifications.
