SPL Parts Front Lower Control Arms

Precision Geometry. Unrivalled Adjustability.

Take complete control of your front-end alignment with SPL Parts Adjustable Front Lower Control Arms. Designed specifically for the BMW F8X (M2, M3, M4), these arms are a total solution for drivers seeking to optimise roll centre, camber, and track width. By replacing the factory arms, you eliminate the flex and binding inherent in OEM rubber bushings, resulting in a more communicative and stable chassis.

The main arm is CNC machined from lightweight 6061-T6 billet aluminium and features SPL's exclusive 4130 Chromoly Double Adjuster. This gun-drilled, nickel-plated component allows for rapid adjustment of camber and track width via a rotating clamp design—completely eliminating the need for jam nuts. Included stainless steel spacers allow for precise roll centre correction on lowered vehicles, while the high-misalignment FK spherical bearings ensure smooth articulation throughout the entire suspension stroke.

Key Features

• Comprehensive Adjustment: Dial in precise roll centre, camber, and track width settings to suit your specific street or track requirements.
• No More Jam Nuts: The exclusive 360-degree rotating clamp and double adjuster design allow for quick, secure locking of settings without fumbling with multiple wrenches.
• Roll Centre Correction: Provided with multiple-size stainless steel spacers to restore optimal geometry on lowered cars.
• Weight Optimised: Features a combination of billet aluminium, gun-drilled Chromoly, and Blue Anodised Titanium hardware to minimise unsprung weight.
• FK Teflon-Lined Bearings: Low-friction, 3-piece rod ends provide maintenance-free operation and eliminate bushing deflection under high cornering loads.
• OEM Integration: The street version includes the necessary headlight levelling sensor adjusting rod.
• Made in the USA: Engineered and manufactured to the highest professional motorsport standards.
