Designed with motorsports use in mind to replace the tear-prone soft rubber factory transmission mounts, a common cause of knocking, mis-shifting and over-revving. Fits RWD vehicles only. Made using CNC machined Aluminium Caps with captive securing bolts and a Black 95A Durometer polyurethane body, they increase stiffness over OE by 375% for complete control over powertrain movement. They are also the perfect accompaniment to our PFF5-4650 Tuneable Engine Mount on E36/E46/E9* models.
Nr 32 on diagram. Requires 1 per car. Replaces the soft OE rubber bush that sits at the end of the gear shifter arm on manual transmission equipped vehicles, a part often overlooked when upgrading transmission components. Made in our Black 95A durometer material and supplied with a plated steel casing, this new part is designed to eliminate all slack in the gear shift and restore precision when changing gear, ensuring the driver has precise control over every gear change.Pairs brilliantly with PFF5-4630 or PFF5-4631 Gear Shift Arm Front Bush
Nr 32 on diagram. Requires 1 per car. PFF5-1932P Shifter Arm Rear Bush & Bracket - Fast-Road/Track is made from in-house CNC-machined 6082-T6 grade aluminium and anodised black to a premium finish. It is paired with a Purple 80A durometer bush, reducing shift arm deflection by 70% over OE for a more connected and precise shifting experience.
Nr 30 on diagram. Requires 1 per car. Supplied complete with M14 bolt, thread locker and Powerflex keyring. The bracket comes on its own without bushes, so you can choose to use it with a variety of bush combinations. Single OE bush, Dual OE bushes, Single OE bush with single PU bush (1 x PFR5-4026) or Dual PU bushes (2 x PFR5-4026). We would recommend dual PU bushes ideally. If you wish to use it with a single OE bush with a single PU bush, then the PU bush would fit in the vacant right-hand mounting hole in the subframe. With the newerF8xM2/M3/M4s 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 yourF8xM2/M3/M4.PFR5-4030 Dual Mount Diff Bracketis made from our in-house CNC machined6082 High-Tensile Aluminiumand 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 movementImproved throttle responseA more controlled and consistent on-off throttle chassis response.Improved tyre-to-road power transfer reducing wheel hopReduced strain on fitted bushesThe corrosion-resistantSatin Black Anodised Aluminium Bracketis optimised for high stress and deflection whilst withstanding high torque loads butis designed to function equallyon standard or modified vehicleswith 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 combiningPowerflexproducts by using our already hugely popular 80A durometerPFR5-4026Rear Diff Mounting Bushfor both subframe rear mounting positions with the addition of ourPFR5-4025Rear Diff Front Mounting Bushesfor the front for the ultimate in differential control and a lasting fast-road or track solution.
Nr 22 on diagram. Requires 1 per car. PFR5-4026 is a replacement bush that features a built-in support washer, providing further stability of the diff under acceleration. PFR5-4026 can also be used in conjunction with our PFR5-4030 dual-mount rear differential bracket to mount two bushes into the factory positions. Made using our signature Black 95A durometer polyurethane and Black anodised 2011-T6 aluminium, to reduce drivetrain deflection and the potential for wheel-hop during hard launches. PFR5-4026 bushes can be fitted with our PFR5-4030 dual-mount rear differential.

We are pleased to introduce PFF5-4020BLK and PFF5-4021BLK Engine Mount Insert Kits, intermediate alternatives to the BMW Motorsport aluminium inserts and much stiffer full replacement engine mounts available on the aftermarket. Made in our Black 95A durometer material, they are designed to fit the voiding of the OE mounts snuggly to restrict engine movement, perfect for those with tuned track cars. Their design and flexibility also mean they can be fitted to the vehicle without removing the engine mounts themselves. Reducing engine/transmission movement by way of upgraded inserts has the following benefits: - Sharper throttle response - Improved gear shifting - More direct power transfer - More balanced on/off throttle handling - Prolonged life of the OE mounts. A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine and chassis. The harder the material used, the greater the NVH transmitted.

This is a replacement part that uses our Black Series material to boost stiffness over the original part by 18% to withstand increased loading seen by this position on the car. PFF5-4001G provides 5.5mm caster adjustability to provide +/- 0.5 caster offset for improved steering feel. Additional caster will also create additional negative camber on turn giving improved tyre contact with the road under heavy cornering. For a non-adjustable version of this bush please use PFF5-4001.
