This coil spring supports one front corner of the vehicle and manages suspension compression and rebound during braking, acceleration, and cornering. Specifically tuned for M030/M031 applications, it helps maintain the correct lowered ride height and sharper handling characteristics of Porsche’s sports suspension.

Installed between the lower control arm and the front strut assembly, the spring compresses and expands with suspension travel, absorbing road impacts while controlling body movement. Proper spring performance is essential for maintaining suspension geometry, steering precision, and predictable handling on sport-tuned vehicles.

Sports suspension springs operate under higher loads and more aggressive driving conditions. Over time, they can weaken or sag, leading to uneven ride height and reduced handling precision. Replacing worn springs restores correct suspension stance and performance while maintaining the characteristics Porsche intended.

When to replace:
• Front ride height appears uneven or lower than specification
• Reduced handling sharpness or increased body roll
• Visible corrosion, cracks, or spring fatigue
• During shock or strut replacement on M030/M031 vehicles
• As part of a sports suspension refresh or alignment correction
