BMW Coilovers for Street Use for BMW Z4 M Roadster S54 (2003-2008)

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.

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 = 10-40mm lowering; Rear = 5-35mm 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.
