Product information

Our polycarbonate windows are hand crafted to order by our experienced UK based team. They are designed to be safe, strong and lightweight, making them ideal for motorsport. They are much stronger than glass and shatterproof, unlike Perspex and other acrylics, so you are well protected whilst driving.

Our standard windows are manufactured from 4mm thick polycarbonate to comply with Motorsport UK regulations, whilst we also offer 5mm FIA compliant and hard-coated options for those looking tougher windows.

All of our windows are available in a choice of clear, bronze or grey polycarbonate so can choose the windows that best suit your car. You also have the option to add window sliders to either one or both of the front door windows depending on your preference.

How long does an order take to ship?

We will confirm receipt of your order straight away and will be in touch if we have any questions regarding your order. Standard polycarbonate orders are usually manufactured and despatched within 1-2 weeks of the order being placed. Specialist orders - for example if you choose hard-coating plastic - will take longer, but we will contact you and discuss this with you. If you need your order by a certain date then please let us know.

Can I fit the window myself?

Yes, it is straight forward to remove an existing window and install a RacePlastics polycarbonate window. There are plenty of guides on YouTube to help you do this.

Can I collect the order myself?

Yes, we usually courier orders out to our customers, but if you contact us, we can arrange for collection from our Leeds factory.

How can I change my order?

If you need to discuss or change your order in any way, please get in touch with the team at the earliest chance. We will always try to accommodate any changes but costs may be incurred if the manufacturing process has already started.

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.
