This spring set supports the full front axle load and controls suspension movement during braking, acceleration, and cornering. Replacing both springs together ensures even load distribution, symmetrical ride height, and predictable handling - especially important for sport-tuned suspension systems.
Installed between the lower control arms and front strut assemblies, the coil springs compress and rebound with suspension travel. Working together as a matched pair, they absorb road impacts, stabilise the vehicle body, and help maintain precise steering response and tyre contact under dynamic driving conditions.
Sport 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. Installing a pair restores correct suspension geometry, factory sport stance, and the sharp driving dynamics 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
