The BMW F-series performance models are well known for their sharp handling, but once the car is lowered or driven aggressively on track, the factory suspension arms can limit alignment adjustment. The Hardrace Rear Lower Arm Front Adjustable (0009350) is designed specifically to address this by replacing the OEM rear lower arm with a stronger, adjustable component.
Designed for BMW F-Series Platforms
This Hardrace rear lower arm is built for BMW F-series M models, including:
-
BMW M2 (F87)
-
BMW M3 (F80)
-
BMW M4 (F82 / F83)
These vehicles already feature advanced suspension setups from the factory, but modifications such as coilovers, wider wheels, or track-focused alignment settings often require additional adjustability that the stock arms cannot provide.
Improved Alignment Control
The adjustable design allows for precise suspension setup, helping maintain proper geometry after lowering the vehicle. This is particularly useful when aiming for performance-oriented alignment settings that improve grip and stability during hard cornering.
Key Features
-
Adjustable arm design for accurate suspension tuning
-
High-strength steel construction for durability under performance driving
-
Performance bushings / pillowball joints to reduce flex
-
Direct bolt-on replacement for the factory rear lower arm
These upgrades improve suspension rigidity and help maintain consistent alignment under load.
Ideal for Modified F-Series Builds
Many F-series owners upgrade their suspension with coilovers or performance springs. Once the ride height changes, the suspension geometry can shift outside factory specifications. An adjustable rear lower arm helps correct this, allowing the rear suspension to be properly aligned and optimized for performance.
For F-series M owners looking to improve handling precision and maintain proper alignment after suspension modifications, the Hardrace Rear Lower Arm Front Adjustable provides a durable and adjustable solution that supports better suspension control and improved driving performance.
