Bilstein B8 Performance Plus Suspension Strut Cartridge

The Bilstein B8 Performance Plus Suspension Strut Cartridge line is a purpose-engineered performance upgrade over factory dampers, designed specifically for use with aftermarket lowering springs. Rooted in Bilstein's decades of motorsports heritage, the B8 Performance Plus series delivers a compelling balance of spirited performance and everyday drivability for enthusiasts who demand more from their suspension system.

Each cartridge is developed with application-specific valving, refined through extensive real-world road testing to ensure optimal damping characteristics across every fitment. The performance-focused design maintains proper spring tension when paired with lowering springs, delivering a sportier, more dynamic driving experience without sacrificing control or ride quality.
