Customer Question: Can I Fit The Mirco MX5 Seat Into My VW Polo 6N MK3?
Customer question
We are often asked whether the Mirco MX5 bucket seat will fit a VW Polo 6N Mk3. It is a sensible question: the 6N's interior is compact, with not much room between the transmission tunnel and the door cards, so it pays to know what will fit before you buy.
The short answer is yes. The MX5 is a compact seat made with small cars and tight cabins in mind, and it suits the Polo's narrow interior well. This guide covers the seat, its dimensions, and the frames and side mounts that go with it.
- Yes, the Mirco MX5 fits the VW Polo 6N Mk3
- The MX5 is a compact fibreglass side mount seat
- It is Road and Track approved, not FIA homologated
- Listed for a 32 to 36 inch waist and drivers under 6ft
- Sparco make a direct fit 6N frame with a 345mm x 271mm pattern
- The MX5 needs side mounts on the frame

The Mirco MX5 bucket seat
The Mirco MX5 is one of the most compact bucket seats we list, made for tight cabins. Despite the name, it is not a Mazda part: MX5 is what Mirco call the shape, and it goes into any car that suits its side mounts and a frame. It is popular in small hot hatches and other cars where the gap between the tunnel and the door card is limited, which is why it suits the Polo 6N so well.
The fibreglass shell is light and stiff, and its side bolsters and shoulder shape hold you well through corners. It comes in velour, vinyl, imitation Alcantara and other trims, all on the same shell. The velour version is listed as 4 point harness compatible and the vinyl version as 6 point.
One correction to the way this seat is sometimes described: the MX5 is Road and Track approved, not FIA homologated. It suits fast road use, track days and sim rigs, but if your event requires an FIA seat, ask us about one of Mirco’s FIA models instead.
Key features of the Mirco MX5:
- Compact fibreglass shell for small interiors
- Side bolsters and shoulder support
- Velour, vinyl, imitation Alcantara and other trims
- Harness slots, 4 point on the velour version and 6 point on the vinyl
- Road and Track approved
- Listed for a 32 to 36 inch waist and drivers under 6ft
Fitment and seat dimensions
The MX5's small dimensions are what make it a good match for the 6N. The narrow shell and moderate height let it sit in the Polo without touching the door or the centre console.
In our experience, the 6N takes a seat of up to roughly 540mm at the shoulders, so the MX5 at 530mm goes in. Its low profile also leaves good headroom. With the right frame and side mounts, the installation is clean and the door closes without trouble.

Our Mirco MX5 range
We list a wide range of MX5 options. Like the rest of Mirco’s seats, it can be configured in many ways, with Mirco quoting more than 250 combinations of trim, stitching, shell colour and embroidery.
Trims include velour, vinyl and imitation Alcantara, each with a different balance of comfort, grip and durability, so you can choose by what the car does: daily driver, track car or show car.

Fitting equipment and frame options
For the MX5, we recommend the Sparco direct fit frame for the Polo Mk3 (6N). It bolts to the factory mounting points in the floor, so there is no fabrication, and it has a 345mm x 271mm pattern. Because the MX5 is a side mount seat, it goes onto the frame with a pair of side mounts, which also lets you set the height and angle. The frames are handed, so choose driver or passenger side.
Two details from the listing are worth knowing. The Sparco frame is for the 6N built from 1994; if your Polo is the 6N2 facelift from 1999, check the floor mounting points match before ordering. And the frame has no seat belt stalk anchor, so if you are keeping the standard belt, you will need a separate anchor on the seat side.
If you are fitting Cobra seats instead, Cobra make their own Polo Mk3 frames with a 291mm x 330mm pattern and the runner included, for Cobra base mount seats. Cobra’s motorsport seats need side mounts on those frames.
An earlier version of this guide also mentioned a Corbeau frame for the 6N, which we no longer list.
Our VW Polo Mk3 seat guide
For the wider picture, our VW Polo Mk3 (6N) bucket seat guide brings together the bucket seats and reclining seats that suit the car and the fitting equipment we recommend. It is the best place to start if you are planning your first seat upgrade or want to check a seat before ordering.
Garreth’s advice for a car this size is to measure the gap between the door card and the console at shoulder height before you choose a shell, and to check where the seat belt stalk sits against a deep bolster. Send us both and we will tell you if a seat has caused problems before.
