Engine mount bush insert kit. Porsche 986 Boxster

Code: 98737502305

Engine mount bush insert kit.

functionfirst

Fits:
Porsche 986 Boxster 2.7ltr - 1999 to 2004
Porsche 986 Boxster S 3.2ltr - 1999 to 2004

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.

About Engine mounts

Enhance Your Porsche Performance with Engine Mounts: Technical Specifications and Benefits

Technical specifications of Performance Engine Mounts:

Performance engine mounts are specialized mounts designed to improve the stability, control, and overall performance of a Porsche's engine.
They are typically made from high-quality materials such as polyurethane or solid aluminum.
Performance engine mounts feature a stiffer construction compared to standard mounts, reducing engine movement and enhancing rigidity.
They come in various designs and options to fit different Porsche models and engine configurations.
Performance engine mounts are available as aftermarket upgrades or standard replacements for Porsche vehicles.

Benefits of upgrading or replacing Performance Engine Mounts for your Porsche:

Improved power transfer: Performance engine mounts minimize engine movement during acceleration, ensuring more efficient power transfer to the wheels and reducing power loss.

Enhanced throttle response: By reducing engine movement and improving rigidity, performance mounts provide quicker and more precise throttle response, resulting in a more engaging driving experience.

Reduced drivetrain slack: Upgrading to performance engine mounts helps minimize drivetrain slack and improves shifting feel, leading to smoother gear changes and enhanced driving dynamics.

Enhanced stability and handling: Performance engine mounts contribute to improved stability during high-speed cornering, reducing engine-induced weight transfer and enhancing overall control and handling.

Reduced wheel hop: Stiffer engine mounts help reduce wheel hop, which can be particularly beneficial during aggressive acceleration or launch control situations.

At Design911, we specialize in providing the correct parts and professional advice for your Porsche. We offer a wide range of performance engine mounts specifically designed for Porsche models, including both aftermarket upgrades and OEM replacements. Our experienced team can assist you in selecting the appropriate engine mounts based on your Porsche model, year, and specific performance goals. We understand the importance of finding the right balance between performance and comfort, and we can guide you in choosing the optimal engine mounts that suit your needs. With our expertise and commitment to customer satisfaction, we can help you enhance your Porsche's performance, responsiveness, and overall driving experience.
