Selecting the Right Suspension

When it comes to enhancing the performance of your Porsche Cayman S, it’s important to start with selecting the right suspension. A performance suspension system is designed to improve your car’s handling, add more power to the front and rear wheels, and maximize its track performance.

To choose the best suspension system, you should understand your driving needs and the type of performance you’re aiming for. For instance, if your primary goal is to improve your Porsche’s cornering ability on the track, a suspension system with a stiffer spring rate and more aggressive dampening would be a good fit. On the other hand, if you’re looking for a smooth ride while cruising around town, a system with softer springs and less aggressive dampening could be a better choice.

You should consider the quality of the parts, reliability, and the reputation of the manufacturer. Reputable manufacturers usually offer better customer support and more reliable products. Don’t compromise on the quality of your suspension system, as it plays a critical role in the overall performance and safety of your vehicle.

Preparing for the Installation

Before embarking on the installation process, it’s important to gather all the necessary tools and parts. This includes the suspension kit, hydraulic jacks, wrenches, screwdrivers, and other related equipment. Also, ensure the working environment is safe and well-lit.

It’s recommended to have the Porsche’s service manual handy. It will provide detailed instructions on various aspects of the car, including the suspension system. Remember, every car is unique, and the Cayman S has its specific design attributes. The manual will guide you with specific information about the suspension system’s fitment and installation.

Installing the Front Suspension

The front suspension is paramount in the Cayman’s handling and steering, making it vital to install it correctly. Start by securely elevating the front of the car with hydraulic jacks. It will give you enough room to work underneath the vehicle. Then, carefully remove the factory-installed suspension components.

With the old suspension removed, begin to install the new components as per the instructions provided by the manufacturer. Make sure to tighten all the bolts and nuts to the correct torque specifications as outlined in the Porsche’s service manual.

Installing the Rear Suspension

Much like the front, the rear suspension also plays a crucial role in the handling and performance of the Cayman. It provides stability at high speeds and improves the car’s cornering abilities.

To install the rear suspension, you need to elevate the back of the car using hydraulic jacks. Subsequently, remove the stock suspension components with care.

When installing the new suspension, ensure that the parts are aligned correctly. Again, tighten all the components to the specified torque settings. Proper alignment and torqueing are integral to the performance and safety of your Porsche Cayman S.

Post-Installation Checks

After the installation is complete, it’s time for some post-installation checks. Check for any loose parts or bolts and ensure all components are securely fitted. Conduct a test drive to ensure the suspension is working as it should. Pay attention to any unusual noises, vibrations, or handling issues. If you notice anything unusual, it’s best to consult with a registered mechanic to diagnose and resolve the issue.

Remember, the aim is to enhance the performance of your Porsche Cayman S. A well-installed performance suspension will provide you with a more responsive, controlled, and exhilarating driving experience. It’s about making a good car even better, one modification at a time.

The Cayman Boxster Variations

Each Porsche Cayman S presents unique opportunities for suspension modifications, especially when considering the various versions of the model. The Cayman and Boxster families boast a range of engine options, body styles, and performance features. Knowing how to accommodate these variations is key to getting the most out of your suspension upgrade.

The Cayman S, for example, features a 2.5-liter turbocharged flat-four engine, while the Cayman GTS offers a 2.5-liter turbocharged flat-six engine. Both options require a different approach in terms of suspension improvement. While the 2.5-liter turbocharged flat-four engine in the S can benefit from a suspension system designed to fit Porsche vehicles with high torque, the GTS may require a system that handles its unique weight distribution.

The same variations hold for the Boxster family. The Boxster 718, for instance, looks similar to the Cayman S but has a different engine configuration, requiring a unique approach to suspension improvement.

Regardless of the model, always check the full details of your car’s specifications before starting the process. This will ensure that the suspension system you select is the perfect match for your vehicle. Don’t forget, every Porsche model is unique and will require a customized approach.

Regular Checks and Maintenance

The installation of a performance suspension in a Porsche Cayman S is not a one-time investment. Once you’ve installed your new suspension, it’s crucial to conduct regular checks and maintenance to keep it in top shape. This includes inspecting the tie rods, fluids, wheels, brakes, intake, exhaust, and interior ECU.

Keep an eye on the condition of your suspension components. Look out for any unusual wear and tear, leakage, or damage. If you spot any of these, consult with a registered user of a Porsche forum or a trusted mechanic.

Your suspension system works in tandem with your car’s other components, so ensure all parts are in sync and working properly. For instance, your brakes’ performance can directly impact your suspension system and vice versa.

Remember to keep your suspension system well-lubricated to minimize friction and ensure smooth operation. Use a high-quality lubricant recommended by the manufacturer or a trusted automotive shop.

Regular maintenance will not only help prolong the lifespan of your suspension system but also keep your Porsche performing at its peak. This will give you the confidence to tackle any road or track with assurance.


Upgrading the suspension on your Porsche Cayman S can significantly enhance your car’s performance, handling, and overall driving experience. Careful consideration of your driving needs, meticulous preparation, and a detailed, methodical approach to installation are key to a successful upgrade. Remember to consider the unique specifications of your Cayman or Boxster model during the selection process and keep up with regular checks and maintenance post-installation.

This process, while complex, is a worthwhile investment for any car enthusiast. Not only does it improve your Porsche’s performance, but it also provides a rewarding and engaging project for those who love to get under the hood. With this guide, we hope you’re now ready to embark on this exciting journey of enhancing your Porsche Cayman S. Remember, a well-maintained performance suspension will provide a more thrilling and controlled driving experience. You’re truly making a good car even better, one modification at a time. Happy motoring!
