SPL Parts Rear Upper Arm Set BMW M2 (G87) / M3 (G80/G81) / M4 (G82/G83)

Precision Camber Control. Superior Durability.

Maintain proper rear geometry and significantly reduce tyre wear on the street and track with SPL Parts Adjustable Rear Upper Arms. Specifically designed for the BMW G8X (M2, M3, M4), these arms are an absolute necessity for lowered vehicles. The factory BMW suspension features an aggressive camber curve through bump travel; these arms provide the adjustment range needed to correct excess negative camber, ensuring maximum traction during acceleration and optimal grip through corners.

This comprehensive kit replaces both the factory rear wishbone and rear guide links (4 arms total). The kit features gun-drilled 2024 aluminium traction links and a 6061-T6 billet aluminium curved camber arm. By swapping soft factory rubber bushings for smooth-articulating, Teflon-lined FK rod ends, you eliminate unwanted bushing deflection. Utilising SPL's innovative Double Adjuster and 360-degree rotating clamp design, alignment changes are quick and precise without removing the arms from the vehicle or fumbling with jam nuts.

Key Features

• Complete Camber Solution: Replaces all four rear upper links (wishbone and guide links) for total control over rear alignment and geometry.
• Innovative Double Adjuster: The curved upper arm allows for precise camber adjustment while installed on the vehicle, saving significant time during alignments.
• Rotating Clamp Design: 6061-T6 aluminium clamps allow for secure locking of settings without the need for traditional jam nuts.
• Weight Reduction: A combination of gun-drilled 2024 aluminium, billet 6061-T6 aluminium, and Blue Anodised Titanium hardware shaves unsprung weight.
• FK Teflon-Lined Bearings: Self-lubricating 3-piece rod ends provide quiet operation, low friction, and eliminate deflection under heavy cornering or acceleration loads.
• Corrosion Resistance: Black Anodised finish on aluminium components and tapered stainless steel knuckle mount spacers ensure long-term durability in all conditions.
• Made in the USA: Engineered and manufactured to professional motorsport standards.
