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 characteristics.
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 precision, and ride comfort.
Coil springs weaken and sag over time due to constant load, mileage, and road conditions. Replacing only one spring can result in uneven ride height and compromised handling. Installing a pair restores correct suspension geometry, factory stance, and predictable driving dynamics.
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

This coil spring supports one side of the vehicle’s suspension, managing compression and rebound during braking, acceleration, and cornering. It helps maintain proper ride height and contributes to stable, balanced handling.
Installed within the suspension assembly, the spring compresses and expands with suspension travel to absorb road impacts and control body movement. Correct spring performance is essential for maintaining suspension geometry, steering accuracy, and ride comfort.
Over time, coil springs can weaken or sag due to constant load, mileage, and road conditions. A worn spring can alter ride height and suspension geometry, negatively affecting handling and tyre wear. Replacing tired springs with new components restores factory-style suspension balance and driving confidence.
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

OEMatch Coil Springs REAR — Control, Stability, Comfort
Rear coil springs for Porsche models support the rear axle and help maintain ride height, traction and balance. They work with dampers to absorb road shocks, preserve suspension geometry and contribute to predictable handling under acceleration, braking and cornering. These springs suit service, restoration and sympathetic tuning.
Available Types
- Standard replacement rear coil springs for service and restoration
- Progressive-rate rear springs to reduce body roll during dynamic driving
- Lowering springs for reduced ride height where compatible with vehicle setup
Understanding OEMatch Coil Springs REAR
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original rear coil springs.
OE (Original Equipment) refers to parts matching original specifications for the rear coil springs and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM rear coil springs engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Rear coil springs are commonly formed from high-tensile steel and finished to resist corrosion. They provide the static support for the rear of the vehicle, define ride height, and determine how the suspension responds under load. OEMatch provides a wide range of Porsche suspension items, with thousands of part references catalogued to support servicing across many model years.
Benefits Include
- Restores correct rear ride height and suspension geometry
- Improves stability and traction under acceleration and cornering
- Reduces body roll and enhances predictable handling
Why Coil Springs REAR Wear and Fail
- Metal fatigue from repeated compression cycles leads to sag or breakage
- Corrosion and surface pitting weaken coils and can cause fractures
- Overloading, impacts or debris damage can deform or break springs
The Importance of Replacing with OEMatch Coil Springs REAR
Replacing worn or broken rear coil springs restores suspension balance and ride height, helping maintain Porsche-specific handling characteristics. Correct springs preserve alignment and load distribution, reduce unwanted body movements and support predictable braking and traction. Using springs matched to the vehicle’s specifications aids consistent chassis behaviour and supports other suspension components.
Advantages
- Made to original-spec dimensions where applicable to maintain geometry
- Available in standard and progressive rates for different priorities
- Finished to resist corrosion and designed for long service life
