Adjustable Rebound Damping

The KW Variant 2 gives shock rebound control to give you more options in fine-tuning the handling of the car. The V2 includes the same features of the V1 kit, including -

• Adjustable Rebound with fixed compression settings - optimal ride comfort then dial in more grip and a better balance with less bodyroll than the standard suspension,
• Stainless steel strut/shock bodies and composite spring perches for superior corrossion resistance,
• Individually height-adjustable - Front = 30-60mm lowering; Rear = 20-50mm lowering,
• TUV approved lowering range and operation,
• Expert engineering and design for ease-of-use and long durability,

This kit is an excellent compromise between a fully-adjustable V3 suspension and the basic V1 street kit. It's great for someone who does not want to make complicated and time-consuming shock adjustments. Just dial in the rebound for more grip and less body motions. Set it back for a compliant street ride.

Coil over suspensions are better engineered suspension options compared to a standard shock + spring package. Since the springs and shocks in a coil over are designed by a team of engineers to work together, there is much better suspension travel and more precisely tuned specifications for spring and shock rates. Using separate shock and spring specs may result in premature coil bind or shock bottoming. And most coil over kits offer more features than the traditional packages. Coil overs are also more useful when larger wheels/tires are used because you can precisely set the ride heights to clear the new tires.

Fitment Note: Wheel spacers may be required depending on wheel/tire sizing and ride height setting.

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. 

Engineered to perform, Powerflex performance polyurethane differential 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.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers. 

BMW’s are known to have failure prone front thrust arm bushings.  The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change.  This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience.  Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure. 

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available!  Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).  We wanted to offer E31, E32, E34, E38, E39, E53, E60, E63, E64, and E83 owners similar levels of handling precision and control for the track and street. 

The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise.  We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting.  The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment.  What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.

We offer these thrust arms with the monoball bushings pre-installed for your convenience. Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set. The bushings are also available separately if you wish to source your own control arms.

Features:

Bearing housing

• Precision CNC machined from 6061-T6 blue anodized aluminum
• Knurled OD to provide the perfect fit for the wide range of thrust arm bore diameters among brands.
• CNC machined 304ss ball joint sleeve inserts, providing a precision fit between the ball joint and the subframe.

One of the tricks for getting your BMW to handle better is to add negative camber to the front wheels. This will put more of the tire's width in contact with the ground during cornering. With more rubber there is more grip. BMWs typically have less camber in the front to create understeer. But if you're running a stock setup on the track or autocross you are giving up speed and time as the front tires run out of grip sooner than they should.

Our E90 E92 E93 fixed camber plates are designed from the knowledge we gained from our highly successful racing campaigns with the E46 in the Speed World Challenge series. Our camber plates are offset for the best camber and caster combination for racing purposes when using the stock-diameter sized springs. Camber increases to -2.5° depending on your individual suspension setup, while only increasing ride height by 6mm. The rate of camber change is virtually unaffected throughout the range of suspension travel, reducing the need for other geometry correction. Fixed mount camber plates are legal in many racing and autocross classes - these are the perfect camber solution when adjustable plates are not allowed in your class.

These are very simple to install, requiring only pressing out locator dowels and studs in your factory strut mounts. See below for detailed instructions.

Upgrade your vehicle's performance with our replacement rear lower control arm inner bushings.

A BMWs sub-frame is the heart of the suspension - as the subframe twists and shifts under load all of the suspension mounting points also move. The rear suspension feels loose and lacks precision. As rubber or hydroelastic bushings wear the bushing deflection gets worse. If you have a highly tuned 335i/xi you're putting even more strain on weak bushings. The solution is a stiffer and more durable material. Even BMW has moved to solid mounts on the F10 M5 and F8X M3/M4. These fully solid E82/E90/E92 aluminum mounts have zero deflection - the subframe does not move at all. The rest of the suspension can work as designed and maintain the proper alignment and motion ratios. The driver will notice the difference as the car is more stable and the handling is more precise.

Although we designed these for use in our racecars, they can work on the street so long as the driver can tolerate some additional noise, vibration, and harshness. These mounts are CNC machined in the USA and made with high-grade aluminum. The set is for all four subframe mounts.
