SUSPENSIONKIT997C2
Product Information
These replacement shock absorbers are compatible with PASM-equipped cars and include built-in cancellation resistors to eliminate dashboard errors. They effectively bypass the Active Suspension Management system, allowing the vehicle to function as though it has standard suspension installed.
Set includes:
2 × 99734304524 – OE Match Front shock absorbers (left + right)
2 × 99733305332 – OE Match Rear shock absorbers (left + right)

Replacement for Car with PASM Electronic Damper Control (option code: 475)
Porsche 997.1 Carrera 2 3.6L
Porsche 997.1 Carrera 2S 3.8L
Porsche 997.2 Carrera 2 3.6L
Porsche 997.2 Carrera 2S 3.8L
Over time, shock absorbers lose their ability to control movement, leading to a less stable, bouncier and less predictable car. Replacing all four dampers at once ensures perfectly matched suspension behavior, consistent ride comfort and proper chassis balance across front and rear.
When to Replace:
• Noticeable bounce, float or instability
• Leaking shock oil on any corner
• Front-end dive under braking or rear squat under acceleration
• Rough ride quality, vibration or knocking noises
• Uneven tyre wear or alignment issues
• Full suspension refresh on higher-mileage 997 models

- They are designed as standard replacement units with built-in electronics to cancel PASM fault warnings.
- For correct functionality and proper vehicle handling, they must be installed as a full set of four (2 × front shock absorbers + 2 × rear shock absorbers)
- Mixing PASM units with OEMatch replacement units is not permitted and may result in suspension imbalance or fault messages.
