SPL Parts front caster/thrust/tension rods for the Porsche 981/991 (911, Boxster, Cayman and 718) provide a wide range of front caster adjustment for precise alignment and improved turn-in response. Low-friction FK spherical bearings replace the soft rubber bushings for a more responsive steering feel, and 6061 aluminum spacers allow anti-dive geometry tuning. The rods are CNC-machined and gun-drilled from 2024 billet aluminum to reduce unsprung weight, use blue-anodized titanium hardware, and feature an exclusive 360-degree rotating clamp for easy alignment adjustment. Designed for use with the OEM or OEM-style front lower control arms.
