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.

Window sliders

Upgrade your vehicle with the Race Plastics Window Slider Kit, designed for both driver and navigator sides. Crafted from the same high-quality polycarbonate as your chosen window, these sliders ensure seamless integration and durability. Choose between two locking systems: the Click-Click Bearing Lock for smooth, rattle-free operation with three adjustable positions, or the Split-Pin Lock for a simple, secure, and reliable solution with two preset positions.

Engineered for flawless fitment and effortless installation, our sliders prevent rubbing and scratching, keeping your windows looking sharp. Whether you need maximum airflow on the track or controlled ventilation on the road, this upgrade delivers race-ready performance. For more details, check out our Window Slider Kits.

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 3 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. Unless otherwise stated, all windows are designed to be fitted into rubber seals, please contact us if you require bolt in versions.

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 Volvo 142 rally car

The Volvo 142, introduced in 1966, might not have looked like a typical race or rally car at first glance. With its boxy design, solid build quality, and focus on safety, it seemed more suited for long-distance cruising than high-speed competition. However, behind its unassuming exterior, the Volvo 142 was a tough, well-engineered machine that became a force in touring car racing and rallying, proving that sometimes, the least expected cars can be the most competitive.
One of the biggest surprises of the Volvo 142’s career was its success in touring car racing, particularly in the European and Scandinavian circuits. Despite being heavier than some of its competitors, the 142 had several key advantages that made it a formidable competitor on the track. Unlike lightweight race cars that struggled with structural integrity over long races, the 142’s stiff chassis and strong body meant it could take punishment and keep going. Thanks to a near-perfect weight distribution and well-designed suspension, the 142 was predictable and controlled in corners, allowing drivers to push hard without unexpected surprises. Powered by Volvo’s B20 engine, a 2.0-litre, four-cylinder powerhouse producing up to 180 horsepower in race trim, the 142 had strong torque and impressive durability, making it a great choice for endurance racing.
During the late 1960s and 1970s, the Volvo 142 became a regular sight in European touring car events, often taking on Ford Escorts, BMW 2002s, and Alfa Romeo GTAs. Privateer teams loved it because it was easy to work on, tough as nails, and could be modified into a serious track weapon. In Scandinavian touring car races, the 142 gained a reputation as a “brick that could fly,” using its strong chassis and relentless reliability to compete at a high level. While it may not have had the outright speed of some rivals, its consistency, durability, and ability to handle aggressive racing conditions made it a favourite among endurance racing teams.
While the Volvo 142’s success in touring cars was impressive, it was in rallying where the car truly cemented its motorsport legacy. Competing in Group 2 and later Group 4 rallying, the 142 became a fearsome competitor in the Scandinavian rally scene, where its tough build and strong powerplant made it a perfect choice for loose gravel, snow, and icy conditions. Unlike front-wheel-drive competitors, the 142’s rear-wheel-drive layout made it perfect for aggressive slides and tail-out action, which worked exceptionally well on fast Scandinavian rally roads. While some rally cars struggled with fragile components, the Volvo 142 was practically indestructible, shrugging off impacts that would sideline lighter, more fragile competitors. Privateer teams loved the 142 because it was built to last, easy to repair, and had strong aftermarket support.
One of the most famous drivers to campaign a Volvo 142 in rallying was Sylvia Österberg, a Swedish rally driver who proved that the 142 was capable of competing against more powerful and purpose-built rally cars. The car’s strong presence in Swedish, Finnish, and European rally championships helped build Volvo’s reputation as a serious motorsport brand, not just a company known for safe road cars.
The Volvo 142 remains one of the most iconic racing and rallying Volvos ever built, known for its unbreakable reliability, surprising agility, and ability to punch above its weight class. While it may have been competing in a time when more glamorous brands like Porsche, Ford, and BMW were stealing headlines, the Volvo 142 quietly built a cult following among hardcore enthusiasts who valued toughness over trends.
Even today, the 142 is a regular sight in historic rally and classic touring car racing events, where its timeless boxy design and howling B20 engine continue to thrill both drivers and spectators. Whether on gravel rally stages or the tight corners of a race track, the Volvo 142 remains a true underdog story, proof that strength, endurance, and a little Scandinavian stubbornness can go a long way in motorsport.
