Engine mount bush insert kit. Porsche 987 gen 1 Boxster /Cayman

Fits:
Porsche 987.1 Boxster 2.7ltr - 2008 to 2008
Porsche 987.1 Boxster S 3.2/3.4ltr - 2008 to 2008

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 987.1 Boxster and Cayman. 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 987.
