CarBahn is proud to announce the Caster Adjuster Assembly for the F8X M3, M4 and M2 Competition models. The CarBahn Caster Adjuster Assembly replaces the rubber bushings in the stock thrust arms with sealed precision ball joints inside machined aluminum housings. As a result of eliminating the deflection that is inherent in rubber bushings, braking stability is improved, and the tendency for the car to follow ruts in the road (especially with wider wheels and tires) is reduced. As an added benefit, the bearings are mounted eccentrically to give approximately 2.1 degrees of adjustable caster range. Unlike most other bearings on the market, the bearings inside the Caster Adjuster are nylon-lined for quiet operation, and are sealed against water and debris intrusion for longevity.
