SPL Parts Adjustable Front Trailing Arms for Porsche 911, 718, Boxster & Cayman 2012-2023 - SPL TR 991

$719.00 $799.00

Fits select 2012-2023 Porsche 911 (991), 718 Boxster/Cayman, Boxster/Cayman (981), and 718 Spyder models.

SPL Parts Front Caster/Thrust/Tension rods provide the range of adjustment necessary to dial in precise front caster settings. When adjusting front camber on the 911 or 718 chassis, caster values inevitably shift; these adjustable arms allow you to compensate for those variances and optimize turn-in response. By replacing factory rubber bushings with low-friction, smooth-articulating FK Spherical Bearings, these arms eliminate deflection for a more communicative and responsive steering feel.

The SPL TR 991 is engineered for high-performance street and track use, featuring 2024 billet aluminum alloy hex rods that are precision CNC machined and gun-drilled to minimize unsprung weight without sacrificing rigidity. The exclusive 360-degree Rotating Clamp design simplifies the alignment process, allowing you to lock in settings without fumbling with traditional jam nuts. Anti-dive geometry can be further tuned using the included 6061 aluminum spacers.
