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 = 35-65mm lowering; Rear = 30-60mm 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 an E39 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.

Fitment Notes: This kit is not for vehicles equipped with EDC or self-leveling suspensions. Wheel spacers may be required depending on wheel/tire sizing and ride height setting.

This item fits the following BMWs:
1997-2003 E39 BMW 525i 528i 530i 540i - Sedan
Not for touring wagons.

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 = 25-55mm lowering; Rear = 25-55mm 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.

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 -

• 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 = 30-60mm lowering; Rear = 25-55mm lowering,
• TUV approved lowering range and operation,
• Expert engineering and design for ease-of-use and long durability,

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!
