Bilstein 46-257499 B12 Pro-Kit Suspension Lowering Kit with Dampers and Springs

The Bilstein B12 (Pro-Kit) suspension kit delivers a comprehensive lowering solution engineered for enhanced handling and aggressive stance. This complete system pairs Bilstein's renowned B8 Performance Plus dampers with precision-matched Eibach Pro-Kit springs to provide a moderate drop of 24-40mm (approximately 0.9-1.6 inches), varying by specific vehicle application.

Key Features:

• Complete kit includes B8 Performance Plus dampers and Eibach Pro-Kit lowering springs
• Application-specific tuning ensures optimal damping rates and spring rates for each vehicle
• Moderate lowering between 24-40mm improves aerodynamics and reduces body roll
• Fixed-height design eliminates the complexity of adjustable systems
• Maintains OE-quality ride comfort while enhancing cornering performance
• Lowered stance provides improved visual appeal without sacrificing driveability

Engineered as a matched suspension system, the B12 Pro-Kit combines Bilstein's monotube damper technology with Eibach's progressive spring design. This pairing ensures that damping force is perfectly balanced with spring rates, preventing the harsh ride or premature wear that can result from mismatched components. The result is a suspension upgrade that delivers sharper turn-in response, reduced body roll during cornering, and a more planted feel at highway speeds, all while maintaining exceptional ride quality for daily driving.
