A genuine Porsche front coil spring pair, manufactured to exact OEM specifications for vehicles fitted with M030 / M031 sports suspension. This set includes two front springs, intended to be installed together to maintain correct suspension balance and geometry.

These springs support the full front axle load while controlling suspension movement during braking, acceleration, and cornering. Specifically tuned for sport suspension, they reduce body roll, improve steering response, and deliver the sharper handling characteristics Porsche intended.

Installed between the lower control arms and front strut assemblies, the coil springs compress and rebound with suspension travel. Their sport-calibrated spring rates work in harmony with Porsche dampers to absorb road inputs while maintaining increased stability, precision, and performance-focused ride quality.

When to replace:
• Front ride height has sagged or become uneven
• Springs show fatigue, corrosion, or damage
• During front shock or strut replacement on M030/M031 vehicles
• Suspension refurbishment or alignment correction
• Reduced handling precision or sport suspension performance
