BMW E93 M3 KW Coil Over Suspensions

BMW E93 M3 KW Coil Over Suspensions KW Coil-Over kits are the final answer to your suspension needs. For most BMW applications, KW makes a kit that will perfectly suit your expectations for ride, handling, fitment, and quality. KW's single-minded focus on coil over suspensions ensures proper vehicle-specific engineering with the correct suspension travel, fitment with OE or KW mounts, and ease-of-use. KW uses inox-stainless steel or aluminum on nearly all of their parts to ensure the maximum level of corrosion resistance. Every Variant kit has been tested and certified by Germany's TUV and comes with a limited lifetime warranty. Their fresh approach to complete suspension assemblies has won them praise from forums and shows to racetracks around the globe. KW uses different levels of kit specification - ranging from mild-mannered to hardcore track-only designs.

Variant 1 - Factory Pre-set Damping - Each V1 Coilover has dampers perfectly tuned for the springs included with the kit. This delivers a comfortable but sporty and controlled ride without being jarring or uncomfortable.

Variant 2 - Rebound Adjustable Damping - The V2 kit adds rebound control to the V1 kit. By making the rebound of the shock adjustable, you are more able to tune the handling of the car to suit your needs. Rebound works with the springs to help keep the tire pressed against the pavement. The compression dampening of the shock remains the same as V1.

Variant 3 - Rebound + Compression Adjustable Damping - The V3 coilovers give you full control over rebound and compression rates and puts you one step closer to a true race-ready suspension. Shock Rebound (infinite) and Compression (14 positions) are adjusted independently so you can precisely change the handling charactertistics to get the best fit for indivdual tracks or fine-tune your car's ride to suit the roads in your area. You've got full control!

DDC - Dynamic Damping Control - KW's own EDC system with electronically controlled shocks on their standard Variant X coil over assembly. This system replaces a factory EDC system or works as an EDC-upgrade. The driver can select any of 3 pre-set shocks damping modes. Or they can upgrade with a KW smartphone app and have greater control over the shock damping.

ClubSport - Rebound + Compression Adjustable Damping, Front Adjustable Camber Plates, Track-spec Spring Rates - The KW Clubsport line is geared for track-focused cars where performance trumps everything else. These kits have stiffer springs with corresponding changes to the shock adjustment range, and front monoball bearing camber plates (for most BMW applications). Because of the narrow focus of this suspension, we recommend using it only on a racetrack. With solid mounts like monoball bearings you gain performance and agility in place of comfort. Shock, Rebound and Compression, and front camber are all adjustable independently so you can precisely change the handling charactertistics to get the lowest lap times for the track you're running. You've got ultimate control!

E90/E92 M3 KW Coilover Kit - DDC ECU Electronically Adjustable The KW DDC coil overs are the next generation of an EDC coilover system. What makes this suspension stand out is the optional WiFi/ iPhone app to select shock damping settings on the go. This kit is based on the successful Variant 3 coil overs but is re-engineered to work as an EDC system. It takes the place of the factory EDC system or installs as a 'stand alone' on a car that does not have the factory EDC. Since this is a performance coil over, you get a suspension that has more capability than the stock or ZCP suspensions for better handling, quicker turn-in, and less bodyroll. The ride height is also adjustable to lower the center of gravity and achieve that perfect stance.

For those that want something more than what the factory EDC can deliver, this is the perfect kit. It functions just like any other EDC, with a new dash mounted button to select 3 pre-programmed shock settings. The coil over front strut and adjustable rear spring perches allow you to set the ride height where you want it. On its own the DDC is an exceptional suspension. But where it really shines is with the iPhone app that allows more options for setting the shocks to just the right stiffness for your needs. This is done over a secure local WiFi module installed in the car that interfaces with the DDC's main shock computer and your iPhone/iPad/iPod.

The app has several amazing features -
  • Adjust front and rear axles independently,
  • Maintain a pre-set stiffness between front and rear axles,
  • Save up to 5 shock damping setups,
  • Share your shock setups with friends
    Installation is in-depth but not overly difficult and detailed instructions are included. No permanent changes need to be made to the car or to the factory wiring. The KW kit comes with everything you will need for a clean and reversible installation. The install of the coil over hardware is the same as any other shock and spring package. From there, you run the wiring from each shock to the new KW shock computer located in the trunk (KW calls it an ECU). The shock computer then plugs into the factory wiring for a seamless install. A KW button can be installed in the dash area to select among 3 pre-set shock settings (the factory EDC button remains but is deactivated). This may require modifying your trim depending on where you want the KW button to be installed. No coding or programming is required so no trip to the dealer! Plug in and done! Professional installation is highly recommended as we estimate an expert technician to take 10-12 hours for the full install.

    Using the iPhone app is very easy. From the Basic screen you have the same three pre-set settings as with the dash button - Comfort, Sport, and Sport+. In the Advanced menu you have control over the damping in both front struts, both rear shocks, and setting the front-rear ratio. You can then save your settings to one of the five slots in the Personal menu. All of this can be done on the fly (please practice safe and responsible driving habits). Shock settings are done from 0-100 (from Comfort to Sport+) and are adjusted in 1% increments. Compression and Rebound motions are adjusted simultaneously. Fine tune shock stiffness for your daily driver and have different settings for any type of driving and course you're on. An ideal setup is just clicks away!

    Other KW DDC Features:
  • Advanced materials and design - stainless steel shock housings, composite adjusters
  • German TUV approval for function and safety
  • Individual height adjustments - front struts are threaded bodies for up to 40mm lowering (1.57"), rear springs use a height-adjustable perch up to 35mm lowering (1.37")
  • Progressive-rate springs for initial ride comfort and track-level handling

    KW Coilover Kit - Variant 1 (V1) - E93 M3 Convertible Factory Pre-set Damping

    The Variant 1 is KW's basic simple and effective coil over kit that is still packed with lots of features -
  • Pre-set damping optimized for a blend of ride comfort and handling with less bodyroll than the standard suspension,
  • Stainless steel strut/shock bodies and composite spring perches for superior corrossion resistance,
  • Individually height-adjustable - Front = 10-35mm lowering; Rear = 5-35mm lowering,
  • TUV approved lowering range and operation,
  • Expert engineering and design for ease-of-use and long durability,
    This is the ideal coil over kit for a E93 M3 Convertible owner who does not plan on tracking or autocrossing the car and just wants a lower, more aggressive stance and better handling. KW has set the shock damping rates to be an excellent balance for a smooth yet taut ride, and to resist bodyroll motions for better handling. The Variant 1 differs from the Street Comfort set in that it has stiffer springs and revised shock settings. If you want a sportier ride and better handling than stock the Variant 1 is an excellent choice.

    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.
    Cars with the factory EDC electronic adjustable shocks must have the system disabled with the optional KW EDC Cancellation Kit (or similar). This is a direct fit for cars without EDC.

    Lifetime warranty!

    Want full control? The KW V3 gives you multiple settings for both rebound and compression. You have full access over ride comfort and handling to dial in that perfect setup. Race teams rely on adjustments to get that perfect lap time and having shock controls at your fingertips is key. KW V3 features -
  • Separate adjustments for compression (14 positions) and rebound (infinite settings),
  • Stiffer springs over stock for less bodyroll than the standard suspension,
  • Stainless steel strut/shock bodies and composite spring perches for superior corrossion resistance,
  • Individually height-adjustable - Front = 10-35mm lowering; Rear = 5-35mm lowering,

    Whether you track the car often or only use it for backroad carving the V3 will give you the tools to set up an ideal handling condition. You can crank it up for smooth and fast surfaces or soften it for city or rough roads. Since each shock is 2-way adjustable you can alter the front-rear balance to account for brake dive or squat during power application coming out of the corner. You are in total control!
