Aluminum-Made Top Mount (A6061)
Most E91 6 CYL kits come with a pillowball top mount on both front and rear, which enables you to experience excellent handling. All the pillowball top mounts in McPherson strut with camber adjustable.
Mono Tube Design
Mono-tube design is adopted for this suspension system as it can retain stable damping and have variety of responses to different road conditions. At 45mm diameter, it extends the amount of oil available for the piston. The 45mm shock body is made from steel (STKMI3C) CNC’d using a precise process to get the highest performance and quality available.
9720 Way Damping Settings
With the external nitrogen reservoirs, to adjustment of the dampening force for both rebound and compression separately is available. 9720 ways of different adjustments can meet all customers needs and for assistance with that 1st place win in every race.
Coil spring
The setup of spring rate is designed for Circuit Master damper of many other racing purposes, such as racing spec, drift spec, and tarmac rally. The spring rate will be perfect due to testing through our XYZ racing team who compete all around the world.
Bump Stop

This is made up of high density of polyurethane (PU). It can absorb a stronger impact force and protect the strut. This is different from rubber, the force bearing and bottom impact is better on this design.
Plug-in Nitrogen Reservoir
The anodized surface is treat with lightweight aluminum (A6061) before sending it to the CNC process. This not a cylinder only function design, we have also added a design to circulate heat dissipation to prevent an unwanted temperature rise.
Double Damping Piston
The main piston in the strut is for absorbing the reaction force from spring, the other one is in the plug-in nitrogen bottle for assisting with the impact on the spring.

Please Note: With our pillow ball top mounts it is also possible to adjust camber degree, the positive effect of this is that you tune your suspension setup and increase the stability and handling of your E91 6 CYL by 10%, however the downside is that the pillow ball may be susceptible to creating a slight noise when driving over big bumps, this noise is not a defect and is not covered by our warranty.

* The lowering height stated is a generic stated value which may not be specific to the these coilovers for this BMW E91 6 CYL, 99% of our vehicle application have a maximum adjustment of up to 120mm however in some applications such as but not limited to: rare and classic vehicles, or vehicles where this maximum drop is not possible due to body shape, wheel and wheel arch design the maximum adjustment levels may differ slightly from the amount stated.
