Bilstein Sports B6 front & rear shock absorbers Porsche 997 C4/C4S/TT 07/2004>>  ❭  SUSPENSION.997.B6KIT

Bilstein Sports B6 front and rear shock absorbers for Porsche 997 Carrera 4, Carrera 4S and Turbo models from 07/2004 with electronic suspension control, offering PASM-compatible damping tailored to these all-wheel-drive 911s.

What This Product Does These Bilstein B6 Sports dampers replace the original front and rear shock absorbers on PASM-equipped 997 C4, C4S and Turbo models. They are designed to work with the factory electronic suspension control, helping maintain consistent damping behaviour across selected modes while renewing worn or leaking original units.

Functions

• Support PASM-equipped suspension with compatible damping characteristics
• Control vertical wheel and body movement over bumps
• Help maintain stable tyre contact with the road surface
• Assist in keeping the car composed during braking and acceleration
• Work with the factory control system to vary damping by mode
• Contribute to a tidy, well-maintained suspension setup when refreshing other components

Symptoms of Fault

• Excessive bouncing or floaty, unsettled ride
• Knocking noises from the suspension area over bumps
• Visible oil leaks on the damper bodies
• Uneven or accelerated tyre wear
• PASM warning messages or inconsistent behaviour between modes
• Car feeling less composed in quick direction changes

Why Replacement Matters Over time, PASM dampers can suffer from internal wear, oil leakage and age-related deterioration, especially on higher-mileage 997 models. Replacing tired units with PASM-compatible Bilstein B6 Sports shock absorbers helps restore predictable damping response so the adaptive system can function as intended. This supports stable handling, consistent behaviour between modes and a more cohesive feel when combined with service items such as mounts and bushes.

FAQs

• Do these work with PASM?
  They are intended for Porsche models with electronic suspension control and are designed to operate with the PASM system when correctly matched to the vehicle.
• Should dampers be replaced in pairs or as a full set?
  They are typically renewed in axle pairs (both fronts or both rears), with many owners choosing to replace all four at the same time on higher-mileage cars.
• Is an alignment required after installation?
  An alignment check is usually recommended after suspension work to confirm geometry is within specification.
• Anything else to replace at the same time?
  It is common to inspect and, if necessary, renew top mounts, bushes and any worn hardware while access is available.
