Take your vehicle's performance to the next level with The KMP Differential Bushing & Bracket Set for BMW F8X M2/M3/M4, designed to optimise axle and driveshaft alignment, particularly on lowered vehicles. By utilising a second rear differential mounting point and raising the differential, this kit ensures better alignment, minimising the risk of premature CV joint failure and improving ground clearance for the differential.

Now Available in Three Variants

Choose the version best suited to your vehicle's purpose:

Solid with Sliding Bushes (original version)

Combines a rigid rear bracket with sliding bushes, allowing for controlled flex in one direction. Perfect for performance builds that balance durability and compliance.

Solid (new – for track/motorsport use)

Fully solid bushes front and rear for maximum stiffness and zero deflection. Ideal for track cars and race use, delivering the most direct power transfer and driveline control.

Street (new – fast road and track use)

A hybrid polyurethane solution that offers improved performance over OEM rubber while retaining some comfort and vibration damping, perfect for fast road cars and dual-purpose Clubsport builds.

Comprehensive Kit for Superior Alignment

This kit includes front bushings, rear subframe bushings, and a new rear bracket featuring two upper mounts instead of the original single-mount design. All mounts are crafted from either solid aluminium, a hybrid delrin/aluminium blend or BMW poly on the street version, providing near-zero deflection and superior durability compared to factory rubber mounts. These materials are ideal for race cars, where minimising deflection is crucial. 

Offset Front Mounts for Optimal Axle Alignment

The front mounts in this kit are offset by 10mm, raising the differential to better align the rear axle shafts with a lowered suspension. This adjustment is essential for preventing premature CV joint failure and ensuring optimal performance in track conditions. The new rear bracket also includes a second mount for the right side bushing, utilising a space in the rear subframe that BMW did not originally use. The bushings in this kit eliminate the factory vibration absorber, and new upper hex bolts are included for easy installation.

Key Performance Benefits

  • Adds a second rear differential mount, reducing load on the OEM mount

  • Raises the differential via offset front bushes to improve CV joint angle, especially important for lowered vehicles

  • Helps prevent premature CV failure and improves long-term drivetrain reliability

Please Note: The front bushing bracket is not included in this kit. The supplied bushings will need to be pressed into your existing bracket, and a small amount of the casting may need to be ground off for clearance.

Does the job
Size: 53" x 48", Style: Starter Wall
Decent look, basic unit. Wasn’t the easiest build, I had to trim panels to get a good fit. Great price, but quality matches that point.

Great socks, watch out for bad seller
Number of Items: 6, Color: Black (6-pairs), Size: Medium
The socks are great, comfy, padded where you want it. I used these for work socks; I have a blend of corporate desk life and maintenance work. I like the low cut so my shoes don't rub the back of my ankle but not so high that socks always fall down. Great for running and sports as well. Been using these for years. Buyer beware though of the particular seller Liegnitz Group: They were late shipping, sent me the wrong socks so I sent for a return and they send me the right ones. My return got delivered back to them but they did not process it and did not send out any new ones. They cancelled my order and acted like I got the right ones all along. Buy from a different retailer.

Comfortable with perfect fit
Number of Items: 6, Color: White (6-pairs), Size: Medium
I have had these socks for a few weeks now and wear them when running. I have small feet at a men's size 7 and they fit perfectly. Most men's socks are to big for my feet. They are pretty thin but well made and have good cushion. I recommend these for anyone that likes ankle socks for athletic activities.
