The Hardrace Rear Front Upper Arm Pillow Ball (0034754) is designed for BMW F8X platform models including the M2, M3 and M4. This suspension upgrade replaces the factory rear upper arms with stronger components that improve chassis precision and allow more accurate suspension alignment.

Using pillow ball joints instead of standard rubber bushings reduces unwanted movement in the suspension, helping the car maintain more consistent geometry during cornering and acceleration.

Fitment

• BMW M2 (F87)

• BMW M3 (F80)

• BMW M4 (F82 / F83)

Key Features

• Pillow ball joints to minimise suspension flex

• Camber adjustment capability for improved alignment setup

• High-strength construction for durability under performance driving

• Improved chassis response and stability

• Direct bolt-on replacement

• Supplied as a 2-piece set ()

Why Upgrade?

The factory suspension arms use rubber bushings that allow movement under load, especially during aggressive cornering or track driving. Pillow ball joints reduce this flex, helping the suspension respond more precisely to driver inputs.

Upgrading to adjustable upper arms also allows the rear camber to be fine-tuned. This is particularly beneficial for lowered vehicles or cars running track-focused alignment settings, where maintaining the correct suspension geometry is essential for handling performance.

For BMW F8X owners running upgraded suspension components such as coilovers or wider wheels, these Hardrace arms provide improved adjustability and chassis control while remaining a direct replacement for the original parts.
