Porsche 997.1 C4 / C4S Coupe 2005 - 2008
* cars with "PASM" electronic damper control (option code: 475)
Diagram ref no 6
This coil spring supports one side of the vehicle’s suspension, managing compression and rebound during braking, acceleration, and cornering. It helps maintain proper ride height and contributes to stable, balanced handling.
Installed within the suspension assembly, the spring compresses and expands with suspension travel to absorb road impacts and control body movement. Correct spring performance is essential for maintaining suspension geometry, steering accuracy, and ride comfort.
Over time, coil springs can weaken or sag due to constant load, mileage, and road conditions. A worn spring can alter ride height and suspension geometry, negatively affecting handling and tyre wear. Replacing tired springs with new components restores factory-style suspension balance and driving confidence.
When to replace:
• Ride height has sagged or become uneven
• Springs show fatigue, corrosion, or damage
• During shock or strut replacement
• Suspension refurbishment or alignment correction
• Reduced handling precision or ride comfort
