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 response.
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 accuracy, and ride comfort.
Coil springs weaken and sag over time due to constant load, mileage, and road conditions. Replacing only one spring can lead to uneven ride height and compromised handling. Installing a matched OE-Match pair restores correct suspension geometry, factory stance, and predictable driving dynamics.
When to replace:
• Front ride height appears lower or uneven
• Noticeable increase in body roll or reduced handling precision
• Springs show corrosion, cracks, or fatigue
• During shock/strut replacement on M030/M031-equipped vehicles
• As part of a sports suspension refurbishment or alignment correction
