SPL Parts 2012+ BMW 3 Series/4 Series F3X Rear Upper Control Arms

Once an F-chassis car is lowered, the factory eccentric washers often can't pull rear camber back into spec. SPL's adjustable rear upper arms give you a much wider camber range and replace the rubber bushings with rod ends, so the alignment stays where you set it under hard cornering, braking and acceleration.

What you get

• Wide rear camber adjustment, enough to align a lowered car properly for street or track.
• 360-degree rotating clamps that lock with a 3/16-inch Allen key. There are no jam nuts to fight with.
• Teflon-lined FK rod ends that pivot smoothly without bushing deflection.
• Gun-drilled 2024 aluminum links, clamps and clevises to keep unsprung weight down, with blue anodized titanium hardware.
• A pair, made in the USA.

Good to know

• Replacement rod ends are available from SPL if you ever need to service the arms.
