What This Product Does:
- The top mount of the front shock/strut is the crucial structural point where the strut’s top end is fixed to the vehicle’s body/strut tower. It supports the spring/damper load, isolates vibration, allows steering rotation (via bearing or mount plate) and maintains suspension geometry.
- Over time, the top mount hardware—cap, washers, plates, mount bearing or rubber isolator—can degrade: rubber may soften or crack, hardware may corrode or loosen, the mount plate may shift under load. These failures can lead to creaks, clunks, poor ride response and degraded handling.
- The overhaul kit replaces all of these components in one go, ensuring the top mount assembly is returned to its proper condition — secure, correctly aligned, free of play, and with correct installed preload.
When You Should Consider Replacement:
- Knocking or clunking noises from the front strut top area—particularly when going over bumps or when steering the wheel. A failing top mount is a common source of such noises.
- Steering feels less precise, or there is increased play or vague feedback in the front end during cornering, possibly due to mount movement under load.
- Ride quality has degraded, or you notice increased vibration, harsher ride or poorer damping response—indicating that the mount is no longer effectively isolating or securing the strut.
- You are replacing the front shocks/struts: since the top mount must be accessed when the strut is removed, replacing the mount kit at the same time is efficient and prevents needing to revisit later.
- Visual inspection or age/mileage factor: If you notice any of the following—cracked mount rubber, corroded top mount nut/cap, missing or damaged mount hardware—it’s wise to replace. Also, if your vehicle has high mileage or has been driven hard, the mount hardware is high on the list of wear items.
- Restores suspension performance & precision: On a high-performance car like a Porsche, the top mount is part of the load path and geometry of the front suspension. If it is worn, the strut may move slightly under load, compromising alignment, tyre contact patch and handling.
- Eliminates noise & improves ride comfort: Many owners report knocking, creaks or harshness that trace back to worn mount caps, washers or mount plates. A fresh kit removes this weak link.
- Prevents escalation of wear or damage: A failing mount can allow movement that stresses the strut shaft, spring seat, mount plate or body mount—leading to more expensive damage. Replacing the mount kit prevents this chain reaction.
- Cost-effective maintenance timing: Since you already remove or support the strut to access the top mount, replacing the mount kit now adds little extra labour cost and avoids needing to revisit the area.

This is for the shock absorber as an additional spring, also known as a bump stop, stopper or helper spring, designed for the front strut assemblies on Porsche 997 models equipped with the Sport chassis (option codes I030 or I480). Front axle suspension assembly for Porsche 996/997 (1998–2012), serving as a rubber stop or bushing integrated into the strut structure.
Fits:
Porsche 997 C2 / C2S / C4 / C4S MKI 2005-08 - Cars with SPORT chassis (Option code: I030/I480)
Porsche 997 C2 / C2S / C4 / C4S MKII 2009-12 - Cars with SPORT chassis (Option code: I030)
This acts as a progressive load-bearing element, cushioning the suspension when the strut nears full compression. It helps prevent harsh bottoming-out, protecting both the strut and chassis from damage during aggressive driving or over bumps.
These components maintain ride quality and handling performance, especially under heavy loading or spirited cornering, keeping the suspension linear and controlled.
Common Issues & Considerations
Wear or Deterioration: Over time, the rubber can compress, crack, or lose elasticity, diminishing its effectiveness. This can lead to harsher suspension impacts at full compression.
Noise or Harsh Feedback: A worn or hardened bump stop can transmit noise or impacts through the cabin, particularly over rough roads or speed bumps.
Sport vs. Standard Suspension: These parts are specific to Sport chassis models. Non-sport setups may not have the same bump stops or use different part numbers, so swapping or replacing must be done accordingly.

This is for the shock absorber as an additional spring, also known as a bump stop, stopper or helper spring, designed for the front strut assemblies on Porsche 997 models equipped with the Sport chassis (option codes I030 or I480). Front axle suspension assembly for Porsche 996/997 (1998–2012), serving as a rubber stop or bushing integrated into the strut structure.
Fits:
Porsche 997 C2 / C2S / C4 / C4S MKI 2005-08 - Cars with SPORT chassis (Option code: I030/I480)
Porsche 997 C2 / C2S / C4 / C4S MKII 2009-12 - Cars with SPORT chassis (Option code: I030)
This acts as a progressive load-bearing element, cushioning the suspension when the strut nears full compression. It helps prevent harsh bottoming-out, protecting both the strut and chassis from damage during aggressive driving or over bumps.
These components maintain ride quality and handling performance, especially under heavy loading or spirited cornering, keeping the suspension linear and controlled.
Common Issues & Considerations
Wear or Deterioration: Over time, the rubber can compress, crack, or lose elasticity, diminishing its effectiveness. This can lead to harsher suspension impacts at full compression.
Noise or Harsh Feedback: A worn or hardened bump stop can transmit noise or impacts through the cabin, particularly over rough roads or speed bumps.
Sport vs. Standard Suspension: These parts are specific to Sport chassis models. Non-sport setups may not have the same bump stops or use different part numbers, so swapping or replacing must be done accordingly.

The shock-absorber compensating plate, also known as spring shim / coil-spring plate for Porsche 996 / 997 / 986 / 987 (OEM part No 996.343.511.00 and 996.343.511.01) is a small metal washer-style plate that sits between the top of the coil spring and the strut top mount/support ring. It’s used to compensate for spring manufacturing tolerances and to ensure the spring seats correctly and the static ride height and geometry are as Porsche intended.
996.343.511.00 – compensating plate (thinner option, commonly ≈ 3.0 mm).
996.343.511.01 – compensating plate (thicker option, commonly ≈ 6.5 mm).

Why are important / when to replace
Correct ride height & geometry: Porsche marks springs with tolerance codes; the correct compensating plate thickness is used to achieve the intended static height and suspension geometry. Using the wrong thickness (or missing the plate) can shift ride height by a few millimeters and slightly alter camber/handling.
Proper spring seating: the plate centers and supports the spring top so the spring doesn’t “walk” or sit unevenly on the top mount — missing/damaged plates can allow the spring to sit off-centre and introduce noise or uneven wear.
During any strut/spring/top-mount job: always inspect/replace these plates when you disassemble the strut. They’re inexpensive and commonly replaced as part of a suspension refresh.
Common issues and symptoms
Clunking or popping noises over bumps or in turns if the spring isn’t seating properly (plate missing, crushed, corroded or installed with wrong orientation).
Incorrect ride height / slight handling changes if the wrong thickness is used (3.0 mm vs 6.5 mm can change static height and the intended spring preload/stack). Enthusiast threads explicitly call out these two thicknesses and their effect.
Corrosion / physical damage: over time OE plates can corrode or get deformed during disassembly — they’re cheap and often replaced because removal can damage them.
