Front Caster Adjustable Control Arms

The Verkline Front Caster Adjustable Control Arms (WAS-410) are engineered for enthusiasts seeking to optimize their Toyota Supra A90/A91's handling. Developed through a comprehensive process involving 3D laser scanning, CAD, FEA, and road testing, these arms provide significant improvements in performance and adjustability. The key benefits include effortless caster adjustment using a turnbuckle jackscrew, leading to precise alignment customization. The increased strength and rigidity of the arms contribute to a more responsive and stable driving experience. Unlike stock components with rubber bushings, these arms maintain their set geometry during alignment procedures, ensuring consistent results. Furthermore, the spherical bearings used are replaceable, meaning wear does not necessitate replacing the entire control arm. Constructed from CNC-machined 6082 T6 aluminum, these control arms feature robust pins and adjustment sleeves made from high-strength steel. They come pre-assembled with a predefined length and are designed as a bolt-in kit, requiring no vehicle modifications. The wishbone is secured to prevent excessive side-swinging. The kit includes all necessary components for installation, including billet aluminum wishbones and mounts, Cr-Mo pins and turnbuckles, spherical bearings, and aluminum spacer sleeves. It is important to note that mounting these control arms may increase noise, vibration, and harshness (NVH). Installation is strongly advised to be performed in a qualified and experienced workshop. The product is sold for off-road, track, and racing applications only. The arms are compatible with the OEM knuckle and subframe.
