PERFORMANCE FEATURES

32 levels of rebound damping adjustment Adjustable damping, monotube shocks/struts paired with optimized progressive rate coil springs gives your vehicle road-sticking grip with reduced body roll for exceptional confidence in your vehicle's handling. With your vehicle's new, lower ride height the center of gravity is now moved lower, further improving handling performance Adjustable front bodies allow you to set the ride height while maintaining correct spring pre-load Adjustable front and rear bodies allow the shock to operate in the correct valving range, regardless of ride height PRODUCT DESIGN

Strut and shock bodies finished with a durable gloss black powder coat for good looks and great longevity Threaded portions are clear zinc-coated for optimum corrosion protection against rain and salt Coil springs are powder-coated Reflex Silver Metallic finish for durability Red anodized, billet aluminum lower spring seats with locking collars allow for quick, on-the-car, adjustability with the included spanner wrenches Integrated bump stops KIT CONTENTS

Bilstein has teamed up with Eibach to offer matched shock and spring packages. These Eibach springs are mated to a special set of Bilstein shocks to deliver a sporty and taut ride with as little impact on ride comfort as possible.

The Pro Kit uses an Eibach Pro Kit spring with Bilstein's Sport shocks and struts. Instead of taking parts from different manufacturers, Bilstein has tested the performance of the Eibach spring and tailored their shocks to be a true match for the new spring rate and ride height. This is known as a matched shock and spring and very few tuning companies take these extra steps. Eibach springs tend to be softer overall than most other aftermarket springs, which ensures the ride stays close to a stock comfort while still giving you a lowered stance and improved handling. 

Bilstein B12 Features: 

• Precise response and excellent driving performance
• Springs and shocks road tested and fine-tuned to complement one another
• Bilstein Monotube/Inverted gas pressure technology
• TUV certified
• Made In Germany
• Average Lowering of 25 to 40mm

Most cars don't need coil overs to improve their handling and bodyroll. For most drivers, simply replacing the shocks and springs with performance versions will meet their goals. If your shocks need replacing, and you felt the handling could be improved a little bit, this is an excellent performance suspension for you.

Bilstein has teamed up with Eibach to offer matched shock and spring packages. These Eibach springs are mated to a special set of Bilstein shocks to deliver a sporty and taut ride with as little impact on ride comfort as possible.

The Sportline kit uses an Eibach Sportline spring with Bilstein's Sport shocks and struts. Instead of taking parts from different manufacturers, Bilstein has tested the performance of the Eibach spring and tailored their shocks to be a true match for the new spring rate and ride height. This is known as a matched shock and spring and very few tuning companies take these extra steps. Eibach Sportline springs are more aggressive than Pro-Kit springs, which tend to be softer overall than most other aftermarket springs, but still ensures ride quality stays close to stock comfort while still giving you a much more aggressive lowered stance and significantly improved handling. 

Bilstein B12 Features: 

• Quick response and precise handling
• Springs and shocks road tested and fine-tuned to complement one another
• Bilstein Monotube/Inverted gas pressure technology
• TUV certified
• Made In Germany
• Average Lowering of 30 to 60mm

Most cars don't need coil overs to improve their handling and bodyroll. For most drivers, simply replacing the shocks and springs with performance versions will meet their goals.

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 = 25-55mm lowering; Rear = 20-50mm 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! 

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 EDC will require the EDC Cancellation Kit (not currently available). Cars without EDC do not need any extra materials.

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 = 35-70mm 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 a Z3 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.

• Individually adjustable rebound and compression
• Infinitely variable rebound damping adjustment
• 14-way adjustable compression damping
• Unique, individually working damping force adjustment
• Stainless steel technology "inox-line"
• Individually height-adjustable - Front = 35-65mm lowering; Rear = 30-60mm lowering,
