Upgrade your front suspension with this comprehensive top-mount kit, designed for front shock/strut towers on Porsche 911 (996 C4 / C4S / Turbo)

What This Product Does:
- The top mount (strut mount) sits between the top of the shock absorber/strut and the vehicle’s body/strut tower. It supports the loads from springs, damper, steering (via bearing), and absorbs vibration/road noise.
- A monoball mount version replaces the standard rubber mount with a spherical bearing (monoball) or very stiff mounting that provides more direct steering/suspension feedback, reduces deflection under load, and keeps suspension geometry (camber, caster) more consistent during hard cornering.
Symptoms & Signs You Need Replacement:
- Clunking or knocking noise from the top of the front strut tower when going over bumps or during steering inputs — a worn mount or bearing often causes this.
- Squeaking or creaking noise when steering the wheel, especially at low speeds — the strut mount bearing may be worn.
- Poor steering feedback or vague handling, especially when cornering hard — a worn mount can cause deflection and loss of camber control.
- Excessive vibration or noise through the body from the front suspension; worn mount rubber or bearing can transmit more noise.
- During a shock/strut replacement or front suspension overhaul — since the top mount assembly must be removed anyway, replacing the modern monoball upgrade kit is logical to restore or upgrade suspension quality.
- Steering geometry issues — if you’ve had camber/caster issues, or your tyres are wearing unevenly at the front, a poor top mount may contribute.
- Suspension performance & tyre contact: On high-performance cars like a Porsche 911 C4/Turbo, the front suspension’s geometry and mounting rigidity matter a lot. If the top mount is deflecting, you lose optimal tyre contact patch under load, which reduces grip, increases tyre wear, and impairs handling.
- Durability & noise/vibration: Rubber top mounts tend to degrade over time (cracking, flattening, absorbing road noise). A good mount + bearing kit eliminates unwanted compliance and noise, and lengthens life of the strut/damper assembly.
- Precise handling and steering feel: The top mount bearing allows the strut to turn with steering; if worn, you get sloppy steering feel and delayed response. Upgrading to a monoball mount helps sharpen the steering and gives more direct feedback.
- Prevents repeat labour: Since access to the strut top requires removing mount or taking down the strut, doing a mount/bearing replacement while everything is open is cost-effective. It avoids having to redo labour later when noise or wear returns.
