Hardrace Front Upper Arm (Pillow Ball) - BMW M3 (G80/G81) | M4 (G82/G83)

Hardrace Front Upper Arm (Pillow Ball) | BMW M3 (G80/G81) & M4 (G82/G83)

Lock In Front Camber for Track-Focused G8x Builds

Lowering a G8x M3 or M4, or simply pushing one hard on track, quickly exposes the compliance built into the factory front upper arm bushing. The Hardrace Front Upper Arm with Pillow Ball joint replaces the factory bushed arm, giving you a solid, deflection-free connection that keeps your front camber setting exactly where you left it - even under heavy lateral load.

Key Features

• Motorsport-Grade Pillow Ball Joint: Eliminates bushing sag and flex for consistent, repeatable front alignment.
• Sharper Steering Response: Removes unwanted compliance from the front suspension for a more direct feel.
• High-Strength Construction: Built to handle the S58's power and the lateral loads of a track-focused G8x.
• 100% Reversible: Direct-fit replacement for the OEM arm, no cutting or permanent modification.
