Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This, in turn, reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.
Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

Servicing your rear differential at regular intervals is important to ensure you maintain both performance and a long lifespan. Over time, the differential fluid can break down, lose its lubricating properties, and become contaminated with metal shavings and debris. Regularly replacing the fluid ensures that the gears and limited slip differential clutch packs are adequately lubricated, reducing wear and tear. Regular maintenance also helps identify potential issues before they become major problems.
This kit includes Genuine BMW differential fluid designed specifically for your M Sport differential and a brand new fill plug. The factory plugs include a rubberized seal that compresses over time and may not seal properly when reused.
One unique aspect of performing this service is the removal of the lower differential temperature sensor. Unlike many typical BMW differentials, this differential does not use a traditional drain plug and instead uses the temperature sensor as a drain plug. This sensor is removed to drain the differential fluid and is replaced before refilling. If you'd like to replace this sensor as well (not included in this kit), please see our recommended items or search BMW part number 33107847469.
NOTE: This kit includes 3 500ml bottles of diff fluid. BMW claims that only 1 Liter of fluid is necessary, but we found that 2 500ml bottles were insufficient. The third bottle included also allows for a minor flush of the old differential fluid before refilling.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.
By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components.
Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

The Powerflex Black Series Rear Diff Front Mount Insert for the BMW F22 (2 Series), F30 (3 Series), and F32 (4 Series) is a robust and high-performance bushing designed for motorsport and aggressive driving. It's part of Powerflex’s Black Series line, which prioritizes precision and control by using a stiffer polyurethane material to enhance the vehicle's dynamics.
Material and Hardness: Made from 95A durometer polyurethane, the Black Series is much firmer than standard bushings, designed specifically for track use. This stiff material drastically reduces unwanted movement in the differential mount.
Enhanced Driving Precision: By reducing flex in the front differential mount, this insert enhances throttle response, reduces wheel hop, and sharpens the overall feel of the drivetrain. This results in better power transfer and improved handling during aggressive acceleration, hard cornering, and rapid gear changes.
Durability: Unlike OEM rubber mounts, which can degrade over time due to exposure to heat, oil, and general wear and tear, Powerflex’s polyurethane inserts are built to withstand harsher conditions, offering greater longevity and reliability.
Simplified Installation: The insert is designed to fit into the existing OEM mount, making installation relatively straightforward without requiring complete replacement of the differential mount. This makes it an efficient and cost-effective performance upgrade.
Performance Trade-off: While the Black Series offers a significant performance boost, it can also slightly increase noise, vibration, and harshness (NVH) inside the cabin. This is a typical trade-off for stiffer, track-oriented mounts.
This insert is popular among BMW enthusiasts who want to upgrade their car’s handling for track days or spirited driving, making the rear-end of the car feel more planted and controlled.

Hands down - one of the best performance upgrades you can make to an E46 M3, E60 M5 or E63/E64 M6! With almost no downside you can make your BMW much quicker by swapping in a new ring & pinion gear set. The gearing used to be overlooked when planning modifications but the 3.85, 3.91, and 4.10 gears are now one of our biggest selling upgrades for the E46 M3! With a rear end gear upgrade you get the effects of adding horsepower but without adding any more stress to the engine or drivetrain. It's one of the best areas to get return from your modification spending. Using a shorter (numerically higher) gear ratio will give you better acceleration. The R&P acts as a torque multiplier, putting the engine into the power band sooner for each gear. There is an 6% increase in torque at the wheels with the shorter R&P. Want to make your car faster off the line or out of corners? Or avoid a downshift to pass on the highway? This is what you need.
The R&P can be installed on its own but for cars that have more than 60,000 miles it would be a better idea to rebuild the whole diff. The factory viscous limited slip units have a typical lifespan of 50-70,000 miles. We offer diff rebuilding with 3.85 or other gear options and you get a fully-rebuilt and serviced limited slip unit at the same time. Click here for our diff rebuild options.
3.85 Gearing Example: 2004 M3, 6-speed manual, 275/35-19" rear tires
Gear RatioGearSpeedRPM
40 MPH in 4th
3.62 4th 40mph 2,250rpm
3.85 4th 40mph 2,350rpm
70 MPH Cruise
3.62 6th 70mph 2,650rpm
3.85 6th 70mph 2,800rpm
5th Gear Speed at Redline
3.62 5th 175mph 8,000rpm
3.85 5th 165mph 8,000rpm
Why 5th? Because 6th does not have the mechanical advantage to get past wind resistance at these speeds - it is more of a cruise/overdrive gear. Using 5th for comparison purposes is much more relevant than having to take into account wind direction, resistance, grade, elevation, tire sizing, etc. These numbers are for comparisons among gear ratios only, not to determine what your M3 will top out at.
This item is the genuine BMW part and the ring & pinion set only. You will need to have this professionally installed into your existing differential. BMW does not supply differential rebuild parts (bearings, shims, plates, etc.) so only a qualified shop that is experienced in BMW diff rebuilding should perform this installation. We also offer built differentials and exchanges, click here.
