034 Motorsport - BMW F20/F30 Chassis Billet Aluminium Rear Differential Insert Kit - 034-505-2026

The BMW F20/F30 Chassis uses rubber differential mounts that deflect under load, causing the delay of power transfer to the rear tires, as well as leading to less-than-optimal handling characteristics during on-throttle and off-throttle transitions. These precision-machined billet aluminium inserts are designed to fill voids in the factory rear differential mounts, and limit differential movement under load without sacrificing ride quality or introducing any perceivable additional noise, vibration, or harshness into the cabin. The result is a more refined, connected driving experience.

Designed to work in conjunction with the factory rubber mounts, this insert package was engineered using CAD software and thoroughly tested and refined to provide a significant improvement in handling performance and feel.

These inserts were tested extensively on 034Motorsport's in-house F30 BMW 340i Development Vehicle before release. Installation is very simple and is completely reversible.

FEATURES:

  • CNC-Machined Billet 6061 Aluminium Construction with Clear Anodized Finish
  • Application-Specific Design for Optimal Fitment and Performance
  • Engineered to Fill Voids in Factory Differential Mount Bushings
  • Reduces Rear Differential Movement During Shifting, Acceleration, and Deceleration
  • Virtually No Additional NVH Transfer Inside Cabin
  • Straightforward Installation

WHAT'S INCLUDED:

  • (Qty. 2) Front Bushing Inserts
  • (Qty. 1) Rear Bushing Insert
  • (Qty. 1) Insert Washer

Works fine 3 months in
Installed a few months ago, before the winter. I was chasing a no-start after replacing the old battery. We've seen single digit temps in the meantime and it is working well. The fit is perfect in a 2010 focus. If you can slide it in from the side and not drop it in from the top, you can replace it without taking off the intake manifold. There are useful videos online showing this. Good luck!

Will be returned as soon as I have a replacement.
When engine is cold starter works fine with engine is hot. It will free wheel the starter motor, but not kick the starter gear into the ring gear on the motor. Watch video and listen it actually did it twice at this location but I didn’t catch the first one on the video.
