Name: BMW 1/2/3/4 Series F2X/F3XProduct Notes: Powerflex Handling Packs contain bushes that have been specifically selected to give the perfect combination of value versus performance based on years of experience. We have chosen products from our range to maximize the performance of the suspension, whilst being mindful of cost with a price saving over buying the parts individually. This can be an ideal upgrade complementing other suspension upgrades such as shock absorbers and springs. Each box includes a complimentary Powerflex keyring and sticker. Powerflex offer improved reliability over original parts and of course carry our Lifetime Warranty. Included within this pack are the following parts:PFF5-1901 Front Radius Arm to Chassis BushPFF5-1902 Front Control Arm to Chassis BushPFR5-1920 Rear Subframe Front Bush InsertPFR5-1921 Rear Subframe Rear Bush InsertPFR5-1927 Rear Diff Front Bush InsertThis Handling Pack contains a selection of parts from a complete vehicle listing, clickhereto see more parts available.Weight: 3500Fitting Instructions

Name: Dual-Mount Rear Differential BracketProduct Notes: 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.

Name: Engine Mount Insert KitProduct Notes: PFF5-4020 and PFF5-4021 Engine Mount Insert Kits are an intermediate alternative to the BMW aluminium inserts and much stiffer full replacement engine mounts available on the aftermarket. Made in our Yellow 70A durometer material, they are designed to fit the voiding of the OE mounts snuggly to restrict engine movement with a minimal increase in NVH, perfect for those with tuned road 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. Fits N52, N54, N55 and B58 engines only. Weight: 167Fitting Instructions
