To ensure these are the lightest adjustable arms available, SPL utilizes blue anodized titanium hardware for high strength without the weight penalty of steel.

Instead of soft factory rubber bushings that deflect under load, these links use high-performance 3-piece FK Rod Ends. These bearings feature a chemically bonded PTFE Teflon liner for quiet operation, low friction, and maintenance-free durability. This design eliminates deflection, ensuring your alignment stays true during high-G cornering and hard acceleration.

SPL Parts Adjustable Rear Lower Camber Arms (RLL) provide precise control over camber, track width, and motion ratios. These arms replace soft factory rubber or polyurethane bushings with high-articulation spherical bearings to eliminate dynamic alignment changes and binding. By increasing arm rigidity, these components improve lateral grip and provide the driver with clearer tactile feedback through the rear suspension.

A standout feature is the three-position mounting system for shocks and sway bar endlinks. These adjustable mounting points allow you to prevent endlink binding and effectively change spring and sway bar rates without replacing hardware. This allows for +/- 13% adjustability in spring effectiveness, making a 6.0 kg/mm spring behave like a 5.2 to 6.8 kg/mm spring depending on the position used.

Fits select 1992-2002 BMW 3 Series (E36) and Z3 models. These SPL Parts Rear Camber Links (RLL) provide the increased adjustment range necessary to correct alignment on lowered vehicles or to dial in aggressive performance settings for street and track use.

By replacing the factory rubber-bushed arms with these adjustable links, you eliminate bushing deflection under load, resulting in more predictable handling and reduced tire wear. The center links, clamps, and clevises are CNC-machined from gun-drilled 6061-T6 aluminum for an optimal strength-to-weight ratio. Adjustment is handled by a 360-degree rotating clamp system secured by blue anodized Titanium socket head cap screws, allowing you to lock in settings with a simple 3/16" Allen key—no more fumbling with jam nuts.

High-end FK rod ends feature a chemically bonded PTFE (Teflon) liner for low friction, smooth articulation, and quiet operation. Designed and manufactured in the USA, these links are built to withstand the rigors of performance driving while maintaining precision tolerances.

• Gun-drilled 6061-T6 aluminum construction
• Blue Anodized Titanium hardware
• 3-piece FK PTFE-lined rod ends
• 360-degree rotating clamp system for easy adjustment
• Eliminates bushing deflection for improved stability
• Proudly made in the USA
• Manufacturer Part Number: SPL RLL E36

Fits 2023+ Toyota GR Corolla.

The SPL Parts Rear Lower Lateral (RLL) Toe Arms provide the precision adjustment needed to dial in rear toe settings on the 2023+ Toyota GR Corolla. These arms are essential for vehicles with lowered ride heights or those driven in competitive track environments where factory adjustment range is insufficient. By replacing the factory links, the SPL RLL E210 kit eliminates the deflection associated with soft OE bushings, ensuring consistent suspension geometry and improved handling predictability.

• Provides a wide range of rear toe adjustment
• Essential for correcting alignment on lowered vehicles
• High-strength design engineered for track and performance street use
• Reduces suspension deflection for more precise cornering
• Manufacturer Part Number: SPL RLL E210

Fits select 2006-2026 BMW 1, 2, 3, and 4 Series, including M2, M3, and M4 models. These SPL Parts Rear Lower Control Arm Knuckle Bushings replace the compliant factory rubber units with high-performance, low-friction Teflon-lined spherical bearings.

By eliminating the soft OEM rubber, these bushings significantly reduce deflection under heavy cornering loads and prevent suspension bind as the arm moves through its travel. This results in more precise wheel rate control and improved rear-end stability. SPL utilizes the largest possible FK bearings to maximize service life and maintain low NVH levels for a performance-oriented ride.

• CNC machined from 6061-T6 aluminum to +/- .001" tolerances for a precise press-fit
• High-load FK Teflon-lined spherical bearings for smooth, maintenance-free operation
• Replaces BMW Part Numbers: 33326775552, 33326756249
• Sold as a pair
