Hardrace Porsche 991 GT3/RS/GT2 RS/Speedster Rear Lower Trailing Arms

Description

Hardrace Porsche 991 GT3/RS/GT2 RS/Speedster Rear Lower Trailing Arms

Rear lower trailing arms control how the rear wheels move under acceleration and braking. These Hardrace arms replace the factory parts with stronger, more precise components to keep the wheel aligned under load. The result is more consistent grip and sharper response without adding unnecessary weight.

Why choose these arms

• High-strength forged aluminium construction for stiffness with low weight.
• CNC-finished for accuracy and consistent geometry.
• Premium pillow ball joints for precise wheel control and faster steering response.
• OE direct replacement – fits factory mounting points.
• Improves handling stability on fast road and track use.

Pillow ball joints are spherical bearings. They reduce flex compared to rubber bushes, so the suspension moves more precisely. This gives clearer feedback and better tyre contact, especially when cornering hard.

Note: Pillow ball joints can increase road noise and vibration compared to rubber. This is normal for performance-focused parts.

Fitment

Designed for Porsche 991 GT models, including GT3, GT3 RS, GT2 RS and Speedster. Please use our vehicle lookup to confirm your car, or check the Vehicle Fitment tab for full details.

Installation and setup

Direct bolt-on replacement for the rear lower trailing arms. We recommend professional installation. Tighten suspension hardware at normal ride height to avoid bushing preload.

Have a four-wheel alignment carried out after installation. This ensures correct tyre wear and handling.
