Customer Question: Can I Fit The Mirco MX5 Seat Into My VW Polo 6N MK3?
One of the most common questions we get from customers is whether the Mirco MX5 bucket seat can be fitted into a VW Polo 6N Mk3. It’s a fair question; the Polo 6N’s interior is compact, with limited space between the transmission tunnel and door panels, so it’s important to know what seats will actually fit without requiring any cutting or modification.
To put it simply, yes, the Mirco MX5 can fit inside the VW Polo 6N Mk3. In fact, it’s one of the best compact FIA-approved bucket seats for this particular model. Designed with small sports cars and tight cabins in mind, the MX5 combines a slim profile with excellent lateral support, making it a great match for the Polo’s narrow interior. The fit is close but clean, giving the cockpit a proper motorsport look while maintaining plenty of room for daily driving comfort and ease of entry.
In this blog, we’ll go over everything you need to know about fitting the Mirco MX5 seat into your VW Polo 6N Mk3. We’ll start by looking at the seat’s design and dimensions, explaining why it works so well in smaller vehicles like the Polo. We’ll also cover the fitting equipment available, including our Corbeau and Sparco direct-fit sub-frames that make installation simple and secure.
If you’re upgrading your Polo for track use, hill climbs, or just spirited road driving, this guide will help you choose the right seat and mounting setup to get the perfect fit. By the end, you’ll have a clear idea of why the Mirco MX5 is such a popular choice for compact cars like the VW Polo 6N Mk3 and how to install it properly with the correct hardware.
The Mirco MX5 Bucket Seat
The Mirco MX5 is one of the smallest and most compact FIA-approved bucket seats in production, designed specifically for tight cabin spaces. It’s often used in cars like Mazda MX-5s, classic Minis, and smaller hot hatches where space between the transmission tunnel and door card is limited. That same compact shape makes it a great match for the VW Polo 6N Mk3 interior, which has a narrow cockpit and limited headroom compared to modern cars.
The seat’s fibreglass shell construction keeps it lightweight yet rigid, providing excellent lateral support and impact resistance. Its high side bolsters and wrap-around shoulder design keep you secure through corners, while the velour fabric trim offers good grip and comfort for both road and track use. The MX5 also features large harness slots suitable for a 4, 5, or 6-point harness setup, meaning it’s ready for anything from fast road driving to full competition use.
Key features of the Mirco MX5 include:
- Lightweight FIA-approved fibreglass shell
- Compact design ideal for small interiors
- High-grip velour trim for comfort and control
- Deep leg and shoulder bolsters for lateral support
- Large harness slots for multi-point harnesses
- Suitable for drivers with a 30–36 inch waist
Fitment and Seat Dimensions
The Mirco MX5’s small dimensions make it a strong candidate for the VW Polo 6N Mk3. Its narrow shell width and moderate height allow it to fit neatly inside the Polo’s cabin without touching the door or center console. Below are the key measurements to give you an idea of just how compact it is.
Seat Dimensions (mm):
- A: Shoulder width – 530 mm
- B: Backrest height – 665 mm
- C: Harness hole height – 375 mm
- D: Base width (front) – 405 mm
- E: Base width (rear) – 475 mm
- F: Overall height – 860 mm
- G: Bolt pattern width – 290 mm
- H: Base depth – 600 mm
- Weight – approx. 7.5 kg
The Polo 6N Mk3 cabin can accommodate seats up to roughly 540 mm at shoulder height without issue, which makes the Mirco MX5 an ideal fit. The seat’s low profile also ensures enough headroom, even for taller drivers. With the correct sub-frame and side mounts, installation is clean, comfortable, and leaves enough clearance for the door to close easily.

Fitting Equipment and Subframe Options
To make installation straightforward, we offer three vehicle-specific seat sub-frames designed to line up perfectly with the factory bolt points in the floor of your VW Polo Mk3 (6N). These frames remove the need for any fabrication or modification, providing a secure and accurate base for your new bucket seats.
We have Corbeau and Sparco sub-frames that use the 345 mm wide bolt pattern, which is one of the most common mount sizes used across the industry for standard-sized bucket seats and sports recliners. This makes them an ideal match for the Mirco MX5 seat, especially when paired with a set of universal side mounts. This combination ensures everything lines up correctly for a quick, reliable installation while keeping your seating position low and comfortable.
For customers planning to use Cobra seats, we also stock Cobra VW Polo Mk3 sub-frames. These frames are built with a narrow 291 mm bolt pattern, specifically designed for Cobra’s range of sports recliners and base-mounted steel-frame bucket seats. Like the Corbeau and Sparco versions, the Cobra frames bolt directly to your Polo’s original seat mounting points, making them a simple, bolt-in solution for Cobra applications.
Whether you’re fitting a Mirco MX5 or a Cobra seat, each of these sub-frame options provides a precise fit, high-quality construction, and compatibility with the correct bolt pattern for your chosen seat. This ensures your installation is as clean, safe, and easy as possible.
