Product information

Race Plastics polycarbonate windows are handcrafted to order by our expert UK team. Designed for motorsport and high-performance use, they’re lightweight, tough, and completely shatterproof—unlike glass or standard acrylics, which can crack under stress.

Our standard windows use 4mm polycarbonate to meet Motorsport UK regulations. We also offer 5mm options that are FIA compliant, plus hard-coated variants for added durability and resistance to scratching.

All windows are available in clear, bronze, or grey tint to suit your vehicle’s design. You can also add window sliders to either or both front doors, depending on your setup.

Window Sliders

Each slider kit is made from the same polycarbonate as your chosen windows. Designed for both driver and passenger sides, these sliders are reliable, practical, and easy to install.

Choose between:

  • Three-position locking with a smooth, rattle-free action
  • Simple two-position setup for fast and secure use

Sliders are engineered to avoid scratching and sit flush with your window kit. Ideal for improving airflow on track days or road builds. More info is available on our Window Slider Kits page.

Shipping times

Once your order’s confirmed, we’ll get started. Most standard orders are manufactured and dispatched within 3 weeks. Custom or hard-coated versions may take a little longer—we’ll contact you with a lead time. If you need your order by a specific date, let us know and we’ll aim to meet it.

Can I fit the windows myself?

Yes, installation is usually straightforward. There are helpful videos online, and our windows are designed to fit into standard rubber seals unless otherwise noted. If you need bolt-in variants, just contact us.

Can I collect my order?

Collection from our UK facility is available by arrangement. Most international orders are shipped, but we’re happy to sort collection if needed—just get in touch.

Want to change your order?

Reach out as early as possible. We’ll always try to accommodate changes, but if manufacturing has already started, there may be a charge.

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.
