Hundreds Of Products Ready Today. Dispatch/Collection Cobra Classic CS Seats into a Mazda MX-5 Mk1
The Mazda MX 5 Mk1 is a car that rewards good seating more than most. Light weight, low seating position, and a compact cockpit mean that the right seat can completely change how the car feels to drive. At the same time, space is tight, and not every aftermarket seat works well without compromising comfort or practicality.
In this build, a pair of Cobra Classic CS bucket seats were fitted into a Mazda MX 5 Mk1 as a road focused upgrade that still delivers improved support over the original factory seats. The Classic CS is a strong choice for MX 5 owners who want a traditional bucket seat shape without moving into aggressive motorsport territory.
Key Factors to Consider When Installing Bucket Seats
The Mazda MX 5 Mk1 is a car that thrives on driver involvement, but the original factory seats can quickly become the weak point as the car gets older or is driven more enthusiastically. Over time, the foam softens, bolsters wear down, and the seat structure itself can lose support. Even in good condition, the standard seats were never designed with fast road or track use in mind.
One of the most noticeable issues is lack of lateral support. When pushing on through corners, the factory seats allow too much movement, forcing the driver to brace against the steering wheel or door card. This not only affects comfort but also reduces control, as your body is not properly supported when the car is working hardest.
Upgrading to an aftermarket bucket seat like the Cobra Classic CS helps lock the driver into a consistent driving position. With better support through the hips and torso, you stay centred behind the wheel, making steering inputs more precise and reducing fatigue over longer drives. This becomes especially noticeable on B roads and during spirited driving, where the MX 5 really comes alive.
Another benefit is improved seating height and posture. The Classic CS sits lower than the factory seat, which lowers the driver’s centre of gravity and improves the sense of connection to the car. For taller drivers, this can also solve common headroom issues, particularly in cars fitted with hardtops or roll bars.
Importantly, this upgrade does not turn the MX 5 into an uncomfortable track car. The Classic CS is still designed for road use, offering a supportive but forgiving shape that works for everyday driving. For many owners, it is about enhancing the car’s strengths rather than changing its character, and a well chosen seat upgrade is one of the most effective ways to do that.
Cobra Classic CS bucket seat overview
The Cobra Classic CS is a fixed-back bucket seat designed with road and fast road use in mind. It uses a lightweight composite shell and a traditional bucket seat shape that offers good support through the hips and torso without being overly restrictive.
Styling is deliberately simple and timeless, which suits older cars like the MX-5 Mk1 very well. The Classic CS does not look out of place in a classic or modern classic interior, and it avoids the aggressive shapes and branding seen on many modern seats.
The seat is trimmed in hard-wearing fabric as standard, with optional upgrades available depending on the finish you want. While it is not FIA-approved for motorsport, it is an excellent option for road cars and occasional track use where FIA certification is not required.
Key features of the Cobra Classic CS include:
- Fixed back bucket seat design
- Lightweight composite shell
- Supportive but forgiving shape
- Traditional styling that suits classic interiors
- Suitable for road and fast road use
Cobra Adaption Bars And Process
The Cobra adaptation bars are specifically designed to facilitate the installation of Cobra seats into the Mazda MX-5 Mk1. These bars serve as a bridge between the vehicle’s original seat sliders and the new Cobra seats, ensuring a secure and proper fit without the need for major modifications.
Understanding the Cobra Adaption Bars
This setup keeps installation straightforward and avoids the need for custom fabrication. It also allows the seat to be positioned correctly for steering wheel alignment and pedal reach, which is especially important in a small cockpit like the MX 5.
Using Cobra adaptation bars ensures compatibility with the Classic CS and provides a solid, proven mounting solution that has been used successfully in many MX 5 builds.
Key Features of Cobra Adaption Bars:
Compatibility: Designed to fit Cobra base-mounted, fixed-back seats with a specific hole pattern (292mm width and 330mm length).
Components Included: Each kit typically includes two adaption bars, a set of M8 bolts in varying lengths, nuts, and spacers to ensure an optimal fit and height adjustment

Step-by-Step Guide to Installing Cobra Classic CS Seats with Adaption Bars:
Preparation:
Remove the original seats from your Mazda MX-5 Mk1, including the original sliders. Ensure you retain the sliders as they will be reused.
Adapting the Sliders:
Detach the sliders from the original seats. These sliders will be bolted onto the new Cobra Classic CS seats using the adaptation bars.
Align the sliders with the holes on the adaption bars. Note that the bars for the driver’s side and passenger’s side are different lengths and must be used accordingly
Attaching the Adaption Bars to the Seat:
Place the Cobra Classic CS seat upside down.
Bolt the adaption bars to the base of the seat using the M8 bolts provided. Ensure the bolts are tightened securely into the captive nuts pre-installed in the seat base.
Mounting the Sliders:
With the seat still upside down, align the original sliders with the holes on the adaption bars.
Use the provided nuts and bolts to secure the sliders to the adaption bars. If necessary, use the spacers to achieve the desired seat height and alignment.
Final Installation:
Once the adaption bars and sliders are securely attached to the seat, position the assembly into the car.
Use the original mounting points and bolts from the MX-5 to secure the sliders (with the seat attached) back into the vehicle.
Adjustments and Testing:
Adjust the seat position using the original sliders to ensure a comfortable driving position.
Ensure all bolts are tightened and the seat is securely fastened before use
Benefits of Using Cobra Classic CS Seats and Adaption Bars

Durable Construction: Made with high-quality materials, the Cobra Classic CS seats are built to withstand the rigors of motorsport while providing longevity for road use.
Easy Installation: The adaption bars facilitate a straightforward installation process, making it possible to upgrade your seats without extensive modifications or professional assistance.
Maintain Original Functionality: By using the original sliders, you retain the seat’s adjustability, ensuring you can find the perfect driving position easily.
Cobra Classic CS Seat Range
The MX 5 Mk1 responds best to upgrades that respect the car’s original character. The Cobra Classic CS does exactly that. It improves support and driving feel without adding unnecessary weight or aggressive styling.
Its simple design complements the MX 5 interior, and its compact size works within the limitations of the cabin. For owners who want a cleaner, more connected driving experience without sacrificing comfort, it is a very sensible choice.
We offer the Cobra Classic CS in a wide range of variations to suit different builds and interior styles. The standard seat is available in several trim material options, including vinyl, leather, corduroy, basketweave, and spacer fabric, making it easy to match both classic and modern interiors.
For customers looking for something more bespoke, the Signature Range takes customisation a step further. This allows you to mix and match different trim materials with a choice of colours, as well as opt for additional finishes such as tartan. It is a good option if you want the seat to feel truly tailored to your car rather than a one size fits all solution.
