Fits 2003-2008 Nissan 350Z and 2003-2007 Infiniti G35 models (All trims including Base, Enthusiast, Nismo, and G35X).

Correct your suspension geometry and dial in precise handling with these SPC Performance front adjustable upper control arms. Engineered specifically for the Z33 and V35 platforms, these arms utilize a patented sliding and rotating ball joint design that allows for easy on-car adjustments of both camber and caster. This design is essential for lowered vehicles to prevent premature tire wear and to optimize the contact patch during spirited driving.

This re-engineered tubular design reduces unsprung weight by approximately 1 lb per arm while significantly increasing rigidity over older versions. The kit is comprehensive, providing the necessary hub and caliper shims for extended camber range and dedicated ABS sensor brackets for a clean, factory-style installation. One kit includes both front arms, sufficient for one vehicle.
