CBF82-3101 – CarBahn F8X M3 M4 Caster Adjuster Assembly Kit

Part Number: CBF82-3101 Category:



The CarBahn Front Caster Adjuster Kit replaces the rubber bushing in the stock thrust arm, resulting in improved braking stability with reduced tendency to follow ruts in the road (especially with wider wheels and tires), additionally allowing for Caster angle adjustments.

Additional Information

CarBahn Autoworks is proud to announce the Caster Adjuster Assembly for the F8X M3, M4 and M2 Competiton models. The CarBahn Autoworks 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.
