Designed for compatible Porsche applications equipped with the specified M029 Standard Suspension, this kit provides replacement components for the front spring assembly and is ideal for repairing worn, damaged or ageing suspension components.

The front coil springs support the weight of the vehicle and allow the suspension to absorb bumps and changes in the road surface. Working together with the shock absorbers and associated mounting components, they help establish the correct ride height while maintaining controlled wheel movement, steering stability and predictable chassis behaviour.

Over time, coil springs can weaken, corrode, sag or fracture. Associated mounting components can also deteriorate through age, mileage and repeated suspension movement. These problems can result in uneven ride height, suspension noise, reduced handling precision and abnormal tyre wear.

Replacing deteriorated components with this OE Match M029 Front Coil Spring Kit helps return the front suspension to its intended operating condition.

What This Product Does:

  • Support the weight of the front of the vehicle.
  • Maintain the specified front ride height.
  • Provide controlled suspension travel.
  • Absorb changes in the road surface.
  • Work together with the front shock absorbers.
  • Maintain the intended M029 Standard Suspension characteristics.
  • Support predictable steering response.
  • Help maintain front-end stability.
  • Control body movement in conjunction with the dampers.
  • Support stable braking and cornering behaviour.
  • Maintain appropriate suspension geometry.
  • Keep the tyres in consistent contact with the road.
  • Restore worn or damaged front suspension components.
  • 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.
  • Suspension bottoming out.
  • Increased body movement.
  • Reduced steering precision.
  • Unsettled or inconsistent handling.
  • Vehicle pulling to one side.
  • Uneven or accelerated tyre wear.
  • Visible corrosion on the springs.
  • Damaged spring coating.
  • Spring incorrectly seated.
  • Cracked or deteriorated associated mounting components.  

Why Replacement Matters:
  • Coil springs are load-bearing suspension components that play an important role in maintaining the vehicle's ride height and suspension geometry.
  • A weakened, sagging or broken spring can alter the relationship between the wheel, suspension and vehicle body.
  • A severely fractured spring can also move out of its intended seating position and potentially interfere with surrounding components.
  • Replacing defective springs helps restore safe and predictable suspension behaviour.
