Product information

Every Race Plastics window is custom-made by our experienced team in the UK. Built for motorsport, these polycarbonate windows are lightweight, shatterproof, and far stronger than glass. Unlike acrylics or Perspex, they won’t crack under pressure—giving you peace of mind when you’re pushing hard.

Our standard spec uses 4mm thick polycarbonate, meeting key racing regulations. If you need more strength, we also offer 5mm FIA-compliant windows and hard-coated options for extra durability and scratch resistance.

Windows come in clear, bronze, or grey tints, so you can match the look to your build. You can also add sliders to either or both front doors, depending on how you want to manage airflow.

Window Sliders

Our slider kits are built from the same high-quality polycarbonate as your main windows. Designed for both driver and passenger sides, they’re smooth, secure, and built to last.

You can choose between:

  • Smooth operation with three fixed positions, no rattle
  • Simple and reliable, with two preset stops

Easy to fit and made to avoid rubbing or scratches, these sliders are ideal whether you need more air on track or better control on the road. For full specs, visit the Window Slider Kits page.

How long does shipping take?

We’ll confirm your order right away. Standard polycarbonate kits are usually built and shipped within 3 weeks. Custom or hard-coated orders may take longer—we’ll reach out to confirm the lead time. If you’ve got a race coming up, let us know and we’ll do what we can to hit your timeline.

Can I install the windows myself?

Yes. Most builds are straightforward and there are plenty of how-to videos online. Unless stated otherwise, our windows are made to fit into standard rubber seals. Need bolt-in versions? Just reach out.

Can I pick up my order?

We usually ship via courier, but yes—collection from our Leeds facility can be arranged. Just drop us a message.

Need to change your order?

Get in touch as soon as you can. We’ll do our best to make changes, but if production’s already started, there may be a cost to amend the order.

The Hillman Avenger 2-door rally car

The Hillman Avenger 2-door, a classic from the 1970s, holds a unique and respected place in the annals of rally history. Born in an era where rallying was rapidly evolving, the Avenger stood out with its distinctive blend of British engineering and a surprisingly sprightly performance under the rally stages' rigorous demands. This unassuming saloon, with its simple yet functional design, was transformed into a formidable rally machine, particularly in its Tiger variant, which was specifically honed for competition. Its rear-wheel-drive setup, coupled with a robust and tunable engine, made the Avenger a joy to handle on the gravel and tarmac stages alike. Its lightweight construction allowed for quick and responsive handling, enabling drivers to extract every bit of performance from the car. The Avenger's reliability and durability were its strongest suits, allowing it to withstand the punishing conditions of rallying, where more sophisticated and powerful cars often failed.

In the rally domain, the Hillman Avenger didn't just participate; it left an indelible mark. It found its niche particularly in national and regional rally championships, where its mix of affordability and competitive performance made it a popular choice among privateers and smaller teams. The Avenger's rallying successes, particularly in the hands of drivers like Andrew Cowan and Rosemary Smith, showcased its capabilities against more established rally marques. It wasn't uncommon to see the Avenger battling fiercely, often punching above its weight class, and securing podium finishes, much to the delight of its loyal fans. The car’s influence extended beyond its active rallying years; it played a pivotal role in developing the grassroots rally scene and inspired a generation of enthusiasts. Today, the Hillman Avenger is revered not just as a vintage rally car but as a symbol of a bygone era where grit, mechanical simplicity, and driver skill were the defining factors of rallying success.
