Product Description

The Torque Solution TS-POR-991 Adjustable Front Caster Arm Kit is engineered for Porsche 981, 982 and 991 chassis applications where additional front caster adjustment is needed. Lowering a Porsche can move the front suspension outside the factory alignment range, making it difficult to achieve the desired geometry. These adjustable arms provide additional adjustment capability to help restore suspension geometry and establish more precise street or track alignment settings.

Each arm is manufactured from high-strength 7075 billet aluminum and uses a PTFE-lined rod end for controlled articulation. The supplied spacer system also provides anti-dive adjustment capability. The black anodized finish adds corrosion resistance, while the direct-bolt-on design allows installation without modifying the vehicle chassis.

The kit contains two assembled caster arms and the required spacer and mounting hardware for the complete front suspension. Professional installation is recommended, followed by a complete wheel alignment. Rod ends are wear items and should be inspected periodically, particularly on vehicles subjected to frequent track use.
