Information
Standard replacement coil spring - suitable for models equipped with "PASM" electronic damper control (option code: 475)
Sold individually – two springs are required per front axle.
We strongly recommend replacing coil springs in pairs.
Fits:
Porsche 997.1 C2 / C2S Coupe 2005 - 2008
* cars with "PASM" electronic damper control (option code: 475)
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

A genuine Porsche coil spring pair, manufactured to exact OEM specifications for material quality, dimensional accuracy, and performance consistency. This set includes two springs, intended to be installed together to maintain correct suspension geometry and balance.
These springs support the axle load and control suspension movement during braking, acceleration, and cornering. Replacing both springs together ensures even ride height, proper weight distribution, and predictable handling response consistent with factory standards.
Installed within the suspension assembly, the coil springs compress and rebound with suspension travel to absorb road impacts and stabilise the vehicle body. Their precisely calibrated spring rates work in harmony with Porsche dampers to maintain tyre contact, steering precision, and overall ride quality.
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

Diagram ref no 6
This spring set supports the axle load and manages suspension movement during braking, acceleration, and cornering. Replacing both springs together ensures even load distribution, symmetrical ride height, and predictable handling characteristics.
Installed within the suspension assembly, the coil springs compress and rebound with suspension travel to absorb road impacts and stabilise the vehicle body. Working together as a matched pair, they help maintain consistent tyre contact, steering precision, and ride comfort.
Coil springs weaken and sag over time due to constant load, mileage, and road conditions. Replacing only one spring can result in uneven ride height and compromised handling. Installing a pair restores correct suspension geometry, factory stance, and predictable driving dynamics.
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
