Designed for compatible Porsche applications equipped with the specified M030 / M031 Sports Suspension, this kit provides replacement components for the rear spring assembly and is suitable for repairing ageing, worn, damaged or corroded suspension components.
The rear coil springs support the vehicle's weight while allowing controlled vertical wheel movement over bumps and changing road surfaces. Working together with the rear shock absorbers and associated suspension components, they help establish ride height, control weight transfer and maintain predictable rear-axle behaviour during acceleration, braking and cornering.
Sports suspension systems depend on springs with the correct characteristics. A weakened, sagging, broken or incorrectly specified spring can alter ride height and suspension geometry, potentially affecting handling balance, traction, tyre wear and stability.
Replacing deteriorated components with this OE Match M030 / M031 Rear Coil Spring Kit helps restore the rear suspension closer to its intended operating condition.
What This Product Does:
- Support the weight carried by the rear suspension.
- Maintain the specified rear ride height.
- Allow controlled suspension movement over uneven surfaces.
- Work together with the rear shock absorbers.
- Maintain the intended M030 / M031 Sports Suspension characteristics.
- Support predictable rear-axle behaviour.
- Help control body movement during cornering.
- Manage weight transfer during acceleration and braking.
- Maintain appropriate rear suspension geometry.
- Support consistent tyre contact with the road.
- Help maintain chassis balance between the front and rear axles.
- Restore worn or damaged rear suspension components.
- Provide an OE Match replacement solution for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Broken or fractured spring coils.
- Rear of the vehicle sitting lower than normal.
- One rear corner sitting lower than the other.
- Uneven ride height.
- Excessive rear suspension sag.
- Reduced ground clearance.
- Knocking or clunking from the rear suspension.
- Metallic noises over bumps.
- Spring moving or sitting incorrectly in its seat.
- Suspension bottoming out more frequently.
- Excessive body movement.
- Rear of the vehicle feeling unsettled.
- Reduced handling precision.
- Unusual behaviour during acceleration or braking.
- Uneven or accelerated rear tyre wear.
- Visible corrosion on the springs.
- Damaged protective spring coating.
- Cracked or deteriorated spring mounting components.
Why Replacement Matters:
- Coil springs are fundamental load-bearing suspension components.
- They help determine vehicle ride height and maintain the designed relationship between the body, wheels and suspension geometry.
- A severely fractured spring may also become displaced from its intended seating position, potentially causing damage to surrounding components.
- Replacing defective springs helps restore controlled and predictable rear suspension operation.
