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
