What’s the Best Way to Install a Roll Cage in a Honda S2000 for Track Safety?

Car enthusiasts and racing aficionados alike can appreciate the allure of the track. The adrenaline, the speed, the sheer mastery of man and machine – it’s a symphony in motion. But with the exhilaration comes an inherent risk. Safety should always be a priority, and for the track-bound Honda S2000 owner, the roll cage is a vital piece of that safety equation.

Choosing the Right Roll Cage for Your Honda S2000

Before you can delve into the installation process, you first need to select the right roll cage for your Honda S2000. Not all roll cages are created equal, and the type you choose will depend on your specific needs and preferences.

A roll cage is designed to protect the driver and passenger in the event of a serious accident. It strengthens the car’s structure and provides a safety system that reduces the potential for injury. The main thing you should consider is the type of racing that you like best. For example, if you prefer high-speed track racing, a full cage is recommended. If you are into autocrossing or street driving, a roll bar could suffice.

In addition, you will need to decide between a bolt-in or weld-in cage. Bolt-in cages are easy to install and remove, making them ideal for street cars that also see track use. On the other hand, weld-in cages are more secure and sturdy, but their installation is more permanent and complex.

Preparing Your Car for Roll Cage Installation

Once you’ve chosen the right roll cage for your Honda S2000, it’s time to prepare your car for the installation process. This means removing any necessary parts to make room for the cage and ensuring the car’s interior is clean and free of debris.

Begin by removing the seats, carpet, and any other interior parts that could obstruct the installation. This includes the center console, dashboard, and any interior trim. Keep these parts in a safe location, as you will need to reinstall them after the cage is in place.

Next, clean the interior of your car thoroughly. Any dirt or debris could interfere with the cage’s installation, leading to potential safety hazards. Use a vacuum cleaner to remove dust and loose debris, then wipe down the interior surfaces with a damp cloth.

Installing the Roll Cage

The actual installation process will depend on the type of cage you’ve chosen. If you’ve opted for a bolt-in cage, you will need to align the cage with the existing holes in your car’s chassis. You can then secure the cage using the provided bolts and nuts.

For weld-in cages, it’s critical that you or the person installing the cage has experience with welding. This is not a job for beginners, and doing it incorrectly could jeopardize the structural integrity of the cage and your safety on the track.

Begin by positioning the main hoop of the cage. This should be positioned directly behind the driver’s and passenger’s seats. Make sure it’s level before welding it in place.

Next, install the front and rear bars. These bars will connect to the main hoop and extend to the front and rear of the car. Ensure they are perfectly aligned before welding them as well.

After the main components are installed, you can proceed with the door bars, roof bar, and any other parts of the cage.

Inspecting Your Roll Cage

Upon completion of the installation, it’s crucial to conduct a thorough inspection of the roll cage. Look for any areas of poor welding, loose bolts, or misaligned bars.

During this inspection, it’s also a good idea to sit in the driver’s seat and check your visibility and comfort. You should be able to see clearly out of all windows, and there should be no obstructions that could inhibit your ability to drive safely.

Next, check the cage’s fit with your racing harness. The harness should be able to securely attach to the cage at the required points.

If you’re satisfied with the installation and the cage has passed your inspection, you can reinstall the car’s interior parts and complete the project.

Installing a roll cage in your Honda S2000 is a considerable project, but it will significantly improve your safety on the track. Remember, the most crucial aspect of this process is choosing a high-quality cage and ensuring it’s installed correctly. This is one area where corners should never be cut.

Roll Cage Design Considerations

When you have chosen the appropriate roll cage for your Honda S2000 and are ready to install, it is highly recommended to consider certain key design aspects. This is critical to ensure that the cage will provide the maximum safety possible when you are racing on the track.

A well-designed roll cage should be as close to the car’s interior as possible. This reduces the likelihood of the driver or passenger coming into contact with the cage during a crash. The main hoop, which is the vertical bar behind the seats, should be positioned to line up with the pillar between the front and rear windows for the same reason.

Furthermore, the roll bars should be designed and positioned to transfer the forces of a crash to the car’s structure evenly. This means they should ideally be attached to strong points in the car’s chassis. Some aftermarket roll bars are designed to attach to weaker points, but for high-speed track racing where the risk of a serious crash is higher, a full cage that attaches to the strong points is a much safer option.

Lastly, the roll cage should be made of a high-strength material like chromoly steel or DOM (Drawn Over Mandrel) steel. This ensures it will be strong enough to withstand the forces of a crash. Moreover, the cage should be designed to prevent intrusion of outside objects into the car’s interior during a rollover, providing additional rollover protection.


Safety is a fundamental consideration when racing, and a roll cage is a critical safety feature that should be installed in your Honda S2000. It is not simply a requirement for HPDEs (High Performance Driver Education events) but a necessity for anyone who values their safety while enjoying the thrills of high-speed track racing.

Choosing the right roll cage involves understanding your racing style, whether you prefer a bolt-in or weld-in cage, and considering the design factors that will provide the best protection in the event of an accident.

Once you have selected the right roll cage, preparing your car for installation, installing the cage, and conducting a thorough inspection are all vital steps to ensure your roll cage is installed correctly and will provide the maximum safety possible.

In conclusion, while the process of installing a roll cage in your Honda S2000 can be daunting, it is a worthwhile investment. It will not only meet the requirements of the track but will also significantly enhance your safety and peace of mind while racing. Always remember, in this process, quality should never be compromised. Safety is paramount, and a well-installed roll cage can be a lifesaver in the unfortunate event of an accident.
