In this review of the Metrix front left lower forward control arm w ball joint, the reviewer finds it best for BMW owners needing an OE-grade replacement without paying dealer prices. The bottom line: this control arm is built to exceed OEM standards and arrives pre-greased, making it a practical choice for DIY mechanics and independent shops who want a long-lasting, ready-to-install chassis part. The review focuses on fitment, durability, and value based on the provided specifications and customer feedback.
Key Features
- Wide vehicle compatibility: Covers many BMW models from 2006 to 2016 so buyers can confirm fitment for common chassis variants without guessing.
- Pre-greased for longevity: Arrives with grease applied which reduces initial wear and saves installation prep time for a smoother initial movement.
- Aluminium construction: Lighter than steel alternatives while resisting corrosion, which helps maintain suspension geometry over time.
- Exceeds OEM standards: Manufactured under IATF 16949 and ISO 9001 processes to offer consistent quality and a durable replacement part.
- Warranty backed: Includes a 3 year / 36,000 miles limited warranty from installation date, providing added confidence after fitting.
Who It's For
The Metrix control arm is ideal for owners of compatible BMW models who want a reliable replacement part that closely matches original equipment specifications. It suits DIY enthusiasts and independent repair shops that value parts arriving ready to install and backed by a multi-year warranty.
It is less suited for owners of vehicles outside the listed compatibility or those seeking an ultra-high performance aftermarket upgrade tuned for track use; in those cases, a purpose-built performance arm would be a better option.
Pros & Cons
Pros
- Good fit and installation feedback from customers, indicating strong compatibility with listed BMW models.
- Quality construction and pre-greased joints reduce break-in wear and simplify installation.
