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 -
This is the ideal coil over kit for an MZ3 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.

The Variant 1 is KW's basic simple and effective coil over kit that is still packed with lots of features -
A coilover is a suspension system that combines a shock absorber with a coil spring wrapped around it. This setup has become widely popular in the automotive aftermarket due to its ability to offer a lower ride height and excellent handling compared to standard shocks.
The KW V3 coilovers stand out with their dual dampening technology, making them suitable for both street and track use. With separate adjustments for rebound and compression dampening, drivers can fine-tune their suspension setup for optimal handling and performance. The patented two-stage valve system allows adjustments for comfort (rebound damping) and driving dynamics (compression damping) in the low-speed range while maintaining fixed settings for high-speed control for enhanced driving safety.
Key Features of the KW V3 Coilovers:
Dual dampening technology with separate rebound and compression adjustments Stainless Steel "Inox-Technology" for durability TüV-approved lowering range High-quality components for long-lasting performance Infinitely variable rebound damping adjustment 14-way adjustable compression damping Unique and precise damping force adjustment Comprehensive documentation for easy installation and setup This V3 coilover system is compatible with all X3M/X4M models and comes with an EDC-cancellation kit to prevent warning lights and drivetrain malfunctions after installation.
KW was founded in 1995, employing only three employees and selling their systems to a small market. Today, KW is represented everywhere and has approximately 200 employees in five locations. KW is currently the epitome of premium components in suspension tuning and refinement. KW offers its customers the largest suspension program worldwide and each component is tested using their state-of-the-art seven-post drive dynamics test.
Tailored for track performance, the KW Clubsport Coilover Kit offers exceptional adjustability, catering to enthusiasts who desire precise ride quality adjustments according to varying loads, tire setups, and other driving factors.
Adjustable Rebound & Compression Damping
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 -
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!

Looking for coilovers that will provide reliability on street driven vehicles but are also capable of feeding your weekend track demon's desire for performance? BC Racing's BR Series coilover kit may be just the thing for you.
BR Series coilovers are the most popular and versatile option offered by BC racing, offering features such as 30-level dampening adjustment (simultaneous compression and rebound control), linear springs where possible, and a minimum of 2 inches ride height drop. To ensure performance, comfort, and quality, all BR Series kits are Dyno tested during the design stage to determine the best valving and spring rates, then installed and tested for a minimum of 6 months. This kit features mounts and brackets that are fully compatible with all stock mounting points and components.
The upper shock/strut mounts are all constructed of 6061-T6 Aluminum for strength and weight savings. BC Racing design 1 of 3 types of upper mounts for each vehicle: Caster/Camber Plates (+/- 3* camber), Camber Plates (+/- 3* camber), and Rubber Mount Plates (NVH reduction). The included mount option for this kit is shown in the kit specs and features below.
Lower shock mounts are powder coated for corrosion protection and constructed of either 6061-T6 aluminum that has been milled from a single piece (fork or bolt eye mount) or of STKM13C steel with all brackets welded robotically.
The included springs come in one of 3 styles: linear, S-barrel, and V-barrel. Linear springs are used in most applications unless limited by the OE design that does not allow the use of linear springs. All spring options are made from SAE9254 steel and have a zinc coating applied under the powder coating for increased spring corrosion protection and long term reliability.
All shock bodies used in the BR Series coilovers use a 53mm shock body (unless noted otherwise) for added strength, performance, and increased fluid capacity. All shocks are then powder coated black chrome for clean styling and corrosion protection.
