The SPL PRO V3 Front Upper Arms deliver precision camber adjustment for Nissan 350Z and Infiniti G35 vehicles. Engineered for both street and track use, these control arms feature SPL's proprietary shim stack adjustment system that provides quick, repeatable camber changes without slipping—ideal for drivers who need to switch between daily driving and track settings.

Key Features:

• CNC machined from billet T6061 aluminum for optimal strength-to-weight ratio
• Motorsports-grade spherical bearings reduce friction and deflection under load
• Camber adjustment range: -2.5° to +1° relative to stock arms
• Typical on-car camber range: -4° to -0.5° (varies with ride height)
• Independent caster adjustment: ±1° off-car adjustment without affecting camber
• No-slip shim stack system for precise, repeatable alignment settings
• Lightweight construction improves suspension response and reduces unsprung weight

These upgraded control arms are designed for enthusiasts who demand maximum performance from their suspension setup. The combination of lightweight aluminum construction and high-quality spherical bearings delivers improved handling precision while maintaining the adjustability needed for track day alignment optimization.
