Suspension Secrets BMW E90 & E92 M3 Adjustable Rear Upper Camber Arms

Enhance the rear-end performance and handling precision of your BMW E90 or E92 M3 with the Suspension Secrets Adjustable Rear Upper Camber Arms—an essential suspension upgrade for achieving accurate camber alignment and maximum grip. Designed for enthusiasts and track-day drivers alike, these arms offer unmatched strength, adjustability, and reliability for optimising suspension geometry on both road and circuit.

Achieve Precise Rear Camber Settings

Lowering your M3 or fitting wider wheels often throws off factory suspension geometry, particularly rear camber. Excessive negative camber can lead to uneven tyre wear and reduced traction. The Suspension Secrets Rear Upper Camber Arms allow you to finely adjust rear camber to your exact specification—restoring proper alignment and unlocking enhanced rear-end stability and grip, especially through high-speed corners.

Engineered with T45 Motorsport Steel

Unlike many aftermarket arms that use aluminium, Suspension Secrets manufacture these camber arms from high-tensile T45 steel—a material trusted in motorsport for its exceptional strength-to-weight ratio and resistance to fatigue. This ensures outstanding durability even under the most demanding driving conditions. Each arm is TIG-welded in-house and finished with a black powder coat for maximum corrosion resistance and long-term performance.

High-Spec PTFE-Lined Rod Ends

To eliminate unwanted movement and provide precise geometry control, the arms are fitted with premium PTFE-lined spherical rod ends. These motorsport-grade joints ensure consistent performance under load and greatly enhance feedback and handling sharpness. For added protection, the rod ends are sealed with rubber dust boots, prolonging service life by shielding them from dirt and moisture.

Simple On-Car Adjustability

The design incorporates both left- and right-hand threads, allowing for quick, hassle-free adjustment without removing the arms from the car. This makes fine-tuning rear camber effortless, whether you’re preparing for a fast road setup or tweaking your track alignment between sessions.

Key Features & Benefits

• Precision Rear Camber Adjustment – Correct alignment issues caused by lowering or wider wheels.
• Constructed from T45 Steel – Offers exceptional strength, fatigue resistance, and durability.

Perfect for Lowered or Modified Vehicles

When running coilovers, lowering springs, or wider rear wheels, maintaining correct rear camber becomes critical to performance and tyre longevity. These adjustable camber arms give you the flexibility to restore factory geometry or set up your M3 for more aggressive cornering, making them a must-have for any performance-focused build.
