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 Mini Classic MK1 rally car

In the annals of motorsport history, few vehicles command the reverence and adoration bestowed upon the Mini Classic Mk1 rally car. From its humble beginnings as a practical urban runabout to its transformation into a rallying legend, the Mk1 Mini has etched its name indelibly in the enthusiast scene.

Introduced in 1959, the Mk1 Mini's revolutionary design captured the imagination of drivers and spectators alike. Its iconic appearance, with its compact dimensions, transverse engine, and unmistakable styling, endeared it to generations of automotive enthusiasts. It was a car that transcended mere transportation; it was a cultural icon.

However, it was on the rally stage where the Mk1 Mini truly cemented its legacy. With its nimble handling, front-wheel-drive layout, and spirited engine, the Mini was perfectly suited for the challenging and diverse terrains of rally competitions. It was a true David among Goliaths, punching above its weight and outmanoeuvring larger, more powerful rivals with ease.

Throughout the 1960s and 1970s, the Mini Classic Mk1 racked up an impressive list of victories and podium finishes in rally events around the world. Its crowning achievement came in 1964 when Paddy Hopkirk and Henry Liddon piloted a Mini Cooper S to victory at the prestigious Monte Carlo Rally, stunning the motorsport world and cementing the Mini's status as a rallying powerhouse.

Central to the Mini's rallying success was the Cooper S variant, developed by the legendary John Cooper. The Cooper S boasted a more powerful engine, upgraded suspension, and aerodynamic enhancements, further enhancing the Mini's performance and competitiveness on the rally stage. It was a true thoroughbred, capable of taking on the toughest rally courses with aplomb.

Even today, the Mini Classic Mk1 rally car continues to be celebrated in the enthusiast scene. Its enduring legacy is a testament to its remarkable design, outstanding performance, and unparalleled success on the rally stage. It remains a symbol of innovation, determination, and the indomitable spirit of motorsport.
