034 Motorsport Billet Aluminum Rear Subrame Insert Kit BMW 2012-2020
$185.40

034 Motorsports Billet Aluminum Rear Subframe Insert Kit

The 034-601-0052 by 034 Motorsports is designed specifically for BMW F2x and F3x chassis models from 2012 to 2020. This kit addresses the inherent deficiencies of the factory rubber rear subframe mounts, which tend to deflect under load, resulting in a vague rear-end feel and compromised suspension geometry.

Construction and Design

Crafted from high-quality 6061 billet aluminum, these inserts are CNC-machined for precision and durability. The clear anodized finish not only enhances aesthetics but also provides additional protection against corrosion. The inserts are engineered to fill voids in the factory mounts, effectively limiting subframe movement without compromising ride quality or introducing additional noise, vibration, or harshness (NVH) into the cabin.

Performance Benefits

  • Maintains proper suspension geometry during cornering, enhancing handling precision.
  • Reduces rear subframe movement during launches and acceleration, improving stability.
  • Improves shifting feel, resulting in crisper and more responsive gear changes.
  • Designed to work seamlessly with factory rubber mounts for a balanced driving experience.

Installation and Kit Contents

Installation of the 034 Motorsports Billet Aluminum Rear Subframe Insert Kit is straightforward and can be completed in under an hour. The process is fully reversible, allowing for easy removal if necessary. Each kit includes:

  • (Qty. 2) Upper Front Inserts
  • (Qty. 2) Upper Rear Inserts
  • (Qty. 2) Lower Front Inserts
  • (Qty. 2) Lower Rear Inserts
