This Kit fits:
BMW M3 F80 (2011 - ) M3
BMW F87 M2 Coupe (2015 on)
BMW F82 / F83 M4 (2014 -)
Notes:
With the newer F8x M2/M3/M4''s making big power and having superb chassis straight from the showroom, it''s no wonder they''re often found at the most serious of track-days or at tuning shops across the globe.
Unfortunately, the power that makes these cars so fun to drive eventually has an impact on the vehicle components, most notably the rear differential bushes.
Despite having the provision for two mounting bushes on the factory tubular subframe, BMW opts to use only a single offset bush to mount the diff bracket to the subframe. This essentially creates a pivot point for the diff under torque loading, especially if the 4x front diff bushes are worn and softened.

With hard launch starts and sudden and frequent on-off throttle changes, this puts the single rear OE rubber bush through extreme torsional and directional forces, resulting in accelerated ageing with failure often seen at around the 30-40,000 mile mark and an unsettled and potentially clunky rear-end.

We are proud to release a high-performance solution to this problem, giving you the tools to re-establish rear-end stability on your F8x M2/M3/M4.
PFR5-4030 Dual Mount Diff Bracket is made from our in-house CNC machined 6082 High-Tensile Aluminium and is designed to utilise the secondary mounting position on the OE subframe. With the addition of a second bush, this prevents the diff from twisting under load, providing benefits such as:
- Reduced drivetrain movement
- Improved throttle response
- A more controlled and consistent on-off throttle chassis response.
- Improved tyre-to-road power transfer reducing wheel hop
- Reduced strain on fitted bushes
The corrosion-resistant Satin Black Anodised Aluminium Bracket is optimised for high stress and deflection whilst withstanding high torque loads but is designed to function equally on standard or modified vehicles with either a single OE bush or dual aftermarket bushes.
Although the bracket can be fitted without the need to remove the subframe from the vehicle completely, we would naturally recommend combining Powerflex products by using our already hugely popular 80A durometer PFR5-4026 Rear Diff Mounting Bush for both subframe rear mounting positions with the addition of our PFR5-4025 Rear Diff Front Mounting Bushes for the front for the ultimate in differential control and a lasting fast-road or track solution.
Powerflex
EPTG Ltd (European Polyurethane Technologies Group) was formed in the UK in 1996 to take advantage of the significant advances made in the development of polyurethane in recent years. The company has wide experience of automotive suspension and chassis systems and combining these design skills with advanced polyurethane manufacturing techniques led to the development of the wide range of high performance automotive polyurethane components now known the world over by the product name POWERFLEX.
The company operates in a self-contained state of the art factory, manufacturing everything in-house. The stainless steel components are machined on the latest computer controlled equipment to ensure perfect repeatability and quality. The moulding and tooling, design and manufacturing is carried out within the factory ensuring very rapid response time to special projects and complete communication between development, prototyping, testing and manufacturing departments. Component manufacturing is carried out with the latest automatic processing equipment ensuring 100% right first time quality. Testing of new components is carried out both on the vehicle and on test rigs. POWERFLEX were selected to receive a Queen’s Award for Enterprise International Trade 2013 and in December 2014 accredited to ISO 9001 as a manufacturer underlining their quality and stature as a global exporter. For those unfamiliar with this it is an international standard to show that the company operates to a system of quality procedures. For smaller companies this can be straightforward but for a company of our size with complex manufacturing and over 2500 part numbers, it is a big achievement especially as this was done with no major changes to our rigorous quality procedures. We were awarded this on our first assessment inspection with no changes or recommendations to the way the business operates. This is a testament to the way we run the business and especially the people within it. All of these factors combined make POWERFLEX the number one selling performance bushes in Europe.
