About Bilstein

Bilstein has been the OE shock supplier to Mercedes-Benz, BMW, Porsche, and Ferrari since 1957. German-engineered B4 OE replacements, B6 sport, B8 lift-corrected, and B14/B16 coilovers — every Bilstein damper carries motorsport-derived monotube technology.

Precision Control for Lowered Porsche 911 Models

The Bilstein B8 Performance Plus rear shock absorber is the premier choice for Porsche 911 owners who have installed aftermarket lowering springs. Because lowered vehicles require dampers with shorter travel and firmer valving to prevent bottoming out and maintain optimal geometry, the B8 is specifically engineered to meet these demands. This 46mm monotube gas-pressure shock provides the aggressive damping force necessary to keep your Porsche composed during high-speed maneuvers.

Why Choose Bilstein B8?

  • Shortened Stroke: Designed specifically for vehicles with lowered ride heights to ensure full suspension travel.
  • Aggressive Valving: Provides superior body control and reduced roll for a more engaging driving experience.
  • Monotube Technology: Delivers consistent, fade-free performance under extreme driving conditions.
  • Sporty Aesthetic: Complements the lowered stance of your 911 with the performance to match.

Compatible with a wide range of 911 variants, including the Carrera, Turbo, and 40th Anniversary editions, the B8 Performance Plus is the gold standard for enthusiasts who refuse to compromise on handling. By pairing these shocks with your lowering springs, you achieve a perfect balance of aesthetic appeal and track-ready precision. Don't let your suspension limit your car's capabilities; upgrade to the B8 and feel the difference in every turn. Discover the ultimate in suspension performance and shop the full Bilstein range at GGCRACING.
