• The shock absorber top mount (sometimes called “strut mount” or “upper mount”) attaches the top of the front damper/strut assembly to the vehicle’s body/strut tower. It supports the spring/damper load, allows steering movement (via the bearing), and isolates noise/vibration.
• Over time, the rubber mount may degrade, the bearing can bind or wear, hardware may corrode — leading to poor ride, noise, loss of precision.
• The overhaul kit replaces the mount, bearing and all relevant hardware so the top of your front suspension is restored to correct specification — improving longevity, ride quality, handling, and eliminating common wear symptoms.

• Knocking, creaking or clunking from the top of the strut tower when driving over bumps or turning the steering wheel.
  
• Steering or handling feel degraded: less precision, vague feedback, increased body roll, front-end wander.
  
• Suspension ride quality worsened, front-end noise or vibration transmitted into the cabin.
  
• You are replacing front shocks/struts: since the top mount must be removed for that job, it’s efficient to replace the mount/bearing/hardware at the same time.
  
• Mount or bearing visibly worn: If inspection shows the mount rubber cracked, bearing flattened or play exists, the overhaul kit is justified.

• The front shock absorber (strut) top mount (sometimes called “strut mount,” “upper mount,” or “mount cap & bearing”) is the part that mounts the top of the front damper/strut to the vehicle’s body (strut tower). It carries spring and damper load, provides a secure connection to the chassis, and often includes a bearing to allow the strut to rotate with steering movement.
• Over time, the top mount’s rubber or elastomer may degrade, the bearing may develop play or noise, the mount plate may shift, washers/nuts may loosen, dust covers may deteriorate. This results in increased noise, worse ride/handling, and possible mis-alignment of the strut.
• This overhaul kit replaces the mount, bearing and all relevant hardware so you restore that top mount area to like new, ensuring proper load path, better durability, reduced noise and proper steering/handling characteristics.
  

• Clunking, knocking or creaking noises from the front strut-tower area when going over bumps or during steering input — a typical symptom of a worn mount or bearing.
  
• Steering feel or front suspension feel has degraded — loose, vague feel, or mis-alignment under load (cornering) can be caused by mount movement or bearing play.
  
• Ride comfort has worsened — a degraded mount transmits more road vibration or noise into the cabin.
  
• You are replacing the front shocks/struts or doing front suspension work — since the top mount is removed/loosened for such work, renewing the mount and hardware at the same time is highly recommended.
  
• Visual inspection may show a cracked or separated mount rubber, bearing play, rusted or worn nuts/bolts, or installer notes of mount movement when the top is pushed.

Designed for compatible Porsche applications equipped with the specified M030 / M031 sport suspension configuration, this kit contains components for the front suspension assembly and is intended to provide an OE-style replacement solution when the existing springs or associated components have become worn, damaged or unsuitable for continued use.

The front coil springs support the weight of the vehicle while allowing the suspension to move over bumps and changing road surfaces. Working together with the dampers and other suspension components, they help maintain the intended ride height, wheel control, steering response and overall chassis balance.

Sport suspension places particular importance on maintaining the correct spring characteristics. A weakened, sagging, damaged or broken spring can alter vehicle height and suspension geometry, potentially affecting handling, braking stability, tyre wear and ride quality.

This OE Match Front Coil Spring Kit provides a comprehensive replacement option for restoring the front suspension on compatible Porsche models with M030 / M031 Sport Suspension.

Designed for compatible Porsche applications equipped with the specified M030 / M031 Sport Suspension, this kit provides replacement components for the front spring and suspension assembly. It is ideal for repairing a worn or damaged front suspension or carrying out a more comprehensive chassis refurbishment.

The front coil springs support the weight of the vehicle while allowing the wheels to move vertically over bumps and changing road surfaces. Working together with the shock absorbers and associated mounting components, the springs help determine ride height, suspension travel and the way the chassis responds during braking, cornering and acceleration.

Sport suspension systems depend on the correct spring specification to maintain their intended balance. A sagging, fractured or incorrect spring can change ride height and suspension geometry, potentially affecting steering response, handling, tyre wear and stability.
