Rear shock mounts are tasked with securing shocks while absorbing noise, vibration and harshness that would otherwise be associated with a solid mount. Factory rubber bushings are a compromise between a cushy ride and responsive handling.

Powerflex polyurethane rear shock mounts are firmer than OEM bushings, resulting in better handling, a more responsive rear-end, and more efficient suspension articulation - all with minimal sacrifice to ride quality.

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.

Koni suspension has taken their long running FSD (Frequency Selective Dampening) Technology and improved upon it to create their new Special Active suspension package. Improving handling while also improving the comfort of your BMW's ride, Special Active shocks and struts prove they are a top contender in the replacement suspension market.

Koni's Special Active dampers adapt to the continuous imperfect road conditions in order to provide you with a more responsive and smoother ride. Thanks to multiple generations of suspension expertise, these shocks and struts rival expensive ride control systems of newer vehicles but at a cost that is significantly lower and a capability to be retrofitted into existing vehicles.

Designed by Koni for the vehicle's original stock ride height, these are not intended to be used with lowering springs and will perform best when paired with stock springs.

Koni Special Active Features:

• KONI’s latest generation of Frequency Selective Damping Technology
•  Improves safety and road holding
•  Technology proven on over 1.5 million factory equipped vehicles
•  Secure and stable feeling for spirited driving
•  Unrivaled aftermarket solution can be fitted to most new and older cars
•  Driving refinement for cars, trucks, SUVs, etc.
•  Technology that rivals expensive Original Equipment electronic systems
•  Performance for driver and comfort for passengers in one

Want a race-spec rear shock mount but with the comfort of a factory bushing? This ECS rear shock mount combines the precision and articulation of a spherical bearing with the isolation of urethane bushings. The stainless monoball bearing is lined with PTFE lubricant and suspended in 80A urethane and housed in a hard anodized 6061-T6 aluminum mount. The spherical bearing is a better design than most rear shock mounts because it allows the shock to move and tilt without side-loading the shock shaft (which leads to premature failure of the shock). Most Genuine BMW and aftermarket shock mounts are not designed for shock angles and the stress that track or performance driving will put on the shock shaft. The ECS shock mount is properly designed to handle these loads. The internal bearing is also replaceable - it will be years before you have to replace the entire mount. The ECS mount is fully encapsulated to prevent the common shock mount failure of the stock mount design.

ECS RSM features:

• Maintenance free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation
• 80A polyurethane isolation bushings for NVH control
• Accommodates 10mm, 12mm, or 14mm damper shafts
• Fully constrained shaft mount makes RSM blow out impossible
• Hard anodized 6061-T6 construction
• Fully rebuildable design

* - the RSM comes with the BMW standard 10mm shock shaft bushings. 12mm is used on some performance shocks and 14mm is used on some true motorsport rear shocks.
