This spring set supports the full front axle load and controls suspension movement during braking, acceleration, and cornering. Replacing both front springs together ensures even load distribution, symmetrical ride height, and predictable handling characteristics.
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 consistent tyre contact for confident steering response 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:
• Front ride height appears uneven or sagging
• Increased body roll or reduced handling precision
• Visible corrosion, cracks, or spring fatigue
• During front shock or strut replacement
• As part of a front suspension refresh

Designed for compatible Porsche applications with PASM, this kit provides replacement components for the front spring assembly, making it ideal for repairing worn, corroded or damaged suspension components as part of a comprehensive front suspension overhaul.
The front coil springs support the weight of the vehicle while allowing the wheels to move over bumps and uneven road surfaces. Working together with the PASM-controlled dampers and associated suspension components, the springs help maintain the correct ride height, suspension geometry, steering response and overall chassis balance.
PASM electronically adjusts damper characteristics according to driving conditions and the selected driving mode. However, the system still depends on mechanically sound springs and mounting components. A weakened, sagging or broken spring can compromise suspension geometry and prevent the chassis from performing as intended.
Replacing deteriorated components with this OE Match Front Coil Spring Kit with PASM helps restore controlled suspension movement, correct vehicle stance and predictable handling.
What This Product Does:
- Support the weight of the front of the vehicle.
- Maintain the specified front ride height.
- Allow controlled suspension movement.
- Work correctly alongside the PASM dampers.
- Maintain appropriate front suspension geometry.
- Support precise steering response.
- Help maintain front-end stability.
- Control body movement in conjunction with the dampers.
- Support stable braking and cornering.
- Maintain consistent tyre contact with the road.
- Replace worn or damaged front spring components.
- Restore the mechanical foundation required for effective PASM operation.
- Provide an OE Match replacement solution for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Broken or fractured spring coils.
- Front of the vehicle sitting lower than normal.
- One front corner sitting lower than the other.
- Uneven ride height.
- Excessive suspension sag.
- Reduced ground clearance.
- Knocking or clunking from the front suspension.
- Metallic noises when travelling over bumps.
- Noise during steering.
- Spring moving within its seat.
- Suspension bottoming out.
- Increased body movement.
- Reduced steering precision.
- Unsettled handling.
- Vehicle pulling or feeling unstable.
- Uneven or accelerated tyre wear.
- Visible corrosion on the springs.
- Damaged spring coating.
- Deteriorated spring seats or mounting components.
Why Replacement Matters:
- Coil springs are structural suspension components responsible for supporting the vehicle's weight and maintaining the intended ride height.
- A severely fractured spring may also move from its intended seating position and potentially interfere with surrounding components.
- Replacing defective springs helps restore safe, controlled and predictable suspension behaviour.

This coil spring supports one front corner of the vehicle, managing suspension compression and rebound during braking, acceleration, and cornering. It helps maintain proper ride height and contributes to stable, predictable handling.
Installed between the lower control arm and the front strut assembly, the spring compresses and expands with suspension travel, absorbing road impacts and controlling body movement. Correct spring performance is essential for maintaining tyre contact, steering accuracy, and overall 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, affecting handling and tyre wear. Replacing tired springs restores factory-style suspension balance and driving confidence.
When to replace:
• Front ride height appears uneven or sagging
• Increased body roll or reduced handling precision
• Visible corrosion, cracks, or spring fatigue
• During front shock or strut replacement
• As part of a front suspension refresh

OEMatch Front Coil Springs — Control, Stability, Comfort
Front coil springs for Porsche models that support vehicle weight, absorb road impacts and work with dampers to maintain ride height and consistent tyre contact. Well-matched springs help preserve steering precision, traction and chassis balance during everyday driving and spirited use.
Available Types- Standard-rate front coil springs for original ride height and replacement
- Progressive-rate and performance-tuned front springs for improved control and reduced body roll
Understanding OEMatch Front Coil Springs
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original front coil springs.
OE (Original Equipment) refers to parts matching original specifications for the front 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 front coil springs engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Front coil springs support the front axle, absorb shock and help stabilise the chassis through acceleration, braking and cornering. They compress and extend in response to road irregularities while dampers control the rate of motion; the spring rate, free length and end fittings determine ride height, initial compliance and how the suspension responds to load and lateral forces.
Benefits Include
- Restores or maintains correct front ride height and suspension geometry
- Improves load distribution and steering response
- Reduces body roll and supports consistent tyre contact
Why Coil Springs Wear and Fail
- Metal fatigue from continuous compression cycles, leading to sag or fracture
- Corrosion from moisture and road salt causing surface pitting and weakness
- Damage from impact or uneven loading, including distorted coils or cracked ends
The Importance of Replacing with OEMatch Front Coil Springs
Fitting new, correctly specified front coil springs restores ride height and handling balance, and helps maintain chassis geometry that affects alignment and tyre wear. Choosing springs matched to Porsche model requirements preserves intended suspension behaviour and interaction with dampers, so steering feel and stability remain predictable. OEMatch focuses on items selected for Porsche applications and provides front springs intended for maintenance, restoration and performance use.
Advantages
- Designed to match original mounting points and spring-seat dimensions where applicable
- Available in standard and performance rates to suit restoration or upgrade requirements
- Supplied with attention to finish and corrosion protection to extend service life
