Upgrade your Porsche’s front suspension with this Heavy Duty / Sport Front Mount Support Insert Set. These are high-durometer inserts designed to replace the factory rubber strut top mounts for a stiffer, more responsive front end.
Used in 911 / 914 and related models with front strut-style suspension, the front mount support (strut top mount) holds the top of the shock/strut assembly to the chassis. The Heavy Duty sport inserts reduce unwanted flex, improve alignment stability under load, and deliver sharper steering feel.

What This Product Does:
Symptoms / Signs Of Wear Or Failure:
- Clunking / knocking / metal noise in the front suspension over bumps
- Steering feel changes / vibration — feedback may feel less crisp
- Increased vibration or harshness transmitted to the body
- Variation in alignment under load — the car geometry may shift during hard cornering
- Wear in strut mount / bearing or excessive play at top of suspension
- Improved Handling Precision: A stiffer mount reduces compliance, so the suspension reacts more faithfully and consistently to road inputs.
- Reduced Flex / Geometry Shift: Under cornering, braking or acceleration, less movement in strut top helps maintain alignment (camber / caster) and wheel path.
- Better Suspension Feedback: The car feels more connected; less mush or “give” at the strut top.
- Cleaner, Tighter Ride: Eliminates looseness and reduces noise / play from aging rubber.
- Longer Life Under Stress: Sport inserts are made from higher durometer / tougher compounds, resisting fatigue, oil, heat, and aging better than soft stock rubber.
