Choose between three hardness levels:
1. Soft (60A) - Orange: For added performance and to restore and preserve your OEM mount with minimal noise, vibration and harshness (NVH)
2. Sport (70A) - Yellow: For tuned and sport-oriented performance street cars, with less noise, vibration and harshness (NVH) than track versions
3. Track (80A) - Black: For optimized performance on track and racecars where noise, vibration and harshness (NVH) is not a consideration
The OEM engine mount was designed for ride comfort and is prone to sagging and tearing but, above all, it is a detriment to performance. The empty voids in the bush allow for too much engine movement, resulting in sloppy handling, numbed responsiveness and imprecise shifting.
Racecars utilize a solid metal mount to mediate this but it is impractical for road use as it transfers extreme noise and vibration into the cabin.
So how do you achieve the benefits of a solid mount while retaining daily drivability? We offer the most effective and easy to install solution for the Porsche 986 Boxster. The durable urethane rubber insert simply slips in to fill and fortify the empty voids of the OEM bush, preventing premature wear and undesirable engine movement, all while transmitting minimal added noise and vibration.
The result? Handling is taut and predictable, power delivery is immediate and smooth and gear changes are crisp and confident.
Installation can be completed in about 1.5-hours for the 986/987.

Why Replace It, Engine mounts are crucial for:
- Locating and supporting the engine
- Absorbing vibration and engine torque under acceleration, braking, and cornering
- When this mount deteriorates or fails, you can expect, Increased vibration transmitted to the cabin, steering, or pedals
- Clunks, bangs, or loud noises during acceleration, deceleration, or gear changes from engine movement against the chassis
- Visual signs such as leaking black fluid from the mount, sagging of tailpipes (due to dropped mounting), or visible damage to rubber or metal components
Common Failure Causes
- Age-related rubber degradation: over time, rubber hardens, cracks or de-bonds, causing loss of damping and allowing engine movement
- Fluid leakage (hydraulic version): loss of damping fluid due to seal failure accelerates failure
- Fluid contamination: oil, coolant, or other contaminants degrade the rubber material
- Vehicle abuse or stress: aggressive driving, hard launches, or previous accidents can warp or break mounts
- Worn or cracked brackets: even if the rubber is intact, the aluminium bracket can be damaged or corroded, reducing effectiveness
