Creating a custom-fit seat insert can completely transform the driving experience, not just in terms of comfort, but in how connected and stable you feel behind the wheel. A snug fit limits unnecessary movement, improves consistency on track, and significantly reduces fatigue during longer sessions. For 2026, the Schroth Indi Resin Bead Kit remains one of the most reliable and effective ways to achieve that bespoke fit without the need for a fully custom-built seat.
At GSM Performance, our focus isn’t just on selling safety equipment; it’s about improving the whole driving experience. We know that your seat is one of the most critical touchpoints in any car, and when it doesn’t fit right, everything else suffers. That’s where the Schroth bead kit comes in. Whether you’re running long stints in an endurance car or trying to get the most from a tightly regulated race series, this kit allows you to mould a seat insert around your exact body shape, ensuring the seat fits you, not the other way around.
As specialists in racewear, composite bucket seats, and FIA-approved safety gear, we’ve seen firsthand how this kit has improved both performance and safety for drivers across a huge range of disciplines. In this guide, we’ll explain what the Schroth Indi Bead Kit does, how it works, who it’s designed for, and why it continues to be a go-to solution in both professional and amateur motorsport circles.
Customisation Meets Safety
The Schroth Indi Bead Kits represent the pinnacle of racing seat technology. Utilizing a vacuum casting bag with unique beads and quick cure resin, these kits allow for a seat that’s perfectly molded to your body. This means enhanced control, reduced movement during high-speed maneuvers, and, most importantly, increased safety through better force distribution in the event of a crash. With a cure time of just 30 minutes, you can achieve a professional-level seat fitment that’s both quick and easy.
Who Is This Kit Designed For?
The Schroth Indi Resin Bead Kit is ideal for motorsport drivers using fibreglass or carbon-fibre bucket seats that need a more personalised fit. It’s especially popular in:
- Touring cars
- Rally and rallycross
- Endurance racing
- Hill climb and sprint events
- Single-seater and prototype classes
If you’re spending long sessions behind the wheel, struggling to find a bucket seat that fits your body shape perfectly, or using a shared seat across multiple drivers, this kit offers a flexible and effective solution. The insert is removable, meaning you can retain the original seat and drop the moulded insert in and out as needed.
What Is a Resin Bead Seat Kit?
A resin bead seat kit is designed to create a custom-moulded insert that sits inside your existing bucket seat shell. It’s made by filling a sealed seat-shaped bag with small polystyrene beads and then shaping it around your body as you sit in your driving position. Once you’re happy with the shape, the resin is mixed and activated inside the bag to harden the bead pack into a permanent, custom-fit insert.
This method replicates the fit of a bespoke race seat but without needing a fully custom seat shell. It improves driver stability, minimises unwanted movement, and increases comfort during longer stints or rough circuit conditions. It’s widely used in endurance racing, rallying, and single-seaters, any discipline where consistency and comfort in the seat are vital to performance.
Why Use a Resin Bead Kit Instead of Foam Padding?
While foam and gel pads can help with comfort, they don’t offer the same level of full-body support that a bead kit does. The resin-moulded insert supports your hips, thighs, and lower back much more precisely. This helps reduce driver fatigue, improves control over the car, and enhances your connection to the seat.
The cured resin structure is also much more durable and holds its shape better over time, especially in high-impact motorsport environments where soft padding can degrade or compress.
Explore the Schroth Indi Bead Kit Range
We stock the full range of Schroth Indi Resin Bead Kits, from 30 litres up to 70 litres, to suit drivers of all sizes and seat shell shapes. Whether you’re building a compact single-seater or fitting out a large GT cockpit, there’s a kit that will suit your setup.
Each size uses the same proven slow-cure resin formula and unique bead blend, combined with vacuum-forming technology to help lock in the ideal driving position. The result is a professional-grade insert that enhances safety, comfort, and overall performance. These kits are trusted in everything from national rally cars to international endurance builds.
The 70-litre Schroth iNDi Seat Kit is the most comprehensive version in the range, offering enough material to fully support taller and broader drivers, or to fill out large competition shells. It’s one of the cleanest, most effective ways to get a fully moulded fit that works with your body and your race seat.
