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 4-door rally car
The Hillman Avenger 4-door, a quintessential 1970s classic, commands a venerable position in rally history. Emerging in a period of significant evolution in rallying, the Avenger was noted for its quintessentially British engineering and unexpectedly spry performance on the demanding rally stages. This modest saloon, with its straightforward yet effective design, was reimagined as a powerful competitor, especially in its Tiger variant designed for racing. The car's rear-wheel-drive configuration and sturdy, adaptable engine made it a pleasure to drive on both gravel and tarmac. Thanks to its light build, it offered nimble and sharp handling, allowing drivers to maximise the car's performance.
In the world of rallying, the Hillman Avenger was more than just a participant; it made a lasting impression. It carved out its place especially in national and regional rally championships, where its balance of affordability and competitive edge made it a favourite among privateers and smaller teams. With notable drivers like Andrew Cowan and Rosemary Smith, the Avenger demonstrated its prowess against more established competitors, often outperforming expectations and achieving podium finishes to the delight of its dedicated followers. The Avenger's influence persists beyond its competitive years, contributing significantly to the development of grassroots rallying and inspiring a generation of rally enthusiasts. Today, the Hillman Avenger is celebrated not only as a classic rally car but also as a symbol of an era when determination, mechanical simplicity, and driver skill defined rallying triumphs.
