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 Vauxhall Astra MK2 rally car

The Vauxhall Astra Mk2, launched in 1984, took everything that made the original Astra a success and refined it into one of the most popular and recognisable hatchbacks of the 1980s. With sleeker styling, improved performance, and a greater focus on practicality, the Mk2 Astra became a staple of British roads, competing head-to-head with the Ford Escort, Volkswagen Golf, and Peugeot 309. It was the car that truly cemented the Astra as a household name in the UK.
One of the biggest changes with the Mk2 Astra was its aerodynamic, more rounded design. Compared to the boxy Mk1, the new model had a more modern, streamlined look, reducing drag and improving fuel efficiency. It was also slightly longer and wider, offering more cabin space and a bigger boot, making it a more comfortable and practical choice for families. The Astra Mk2 was available in three-door and five-door hatchbacks, a four-door saloon, an estate, and even a convertible, ensuring there was a version to suit every type of buyer.
Under the bonnet, the Astra Mk2 came with a wide range of engines, from 1.2-litre economy models to 1.8-litre fuel-injected variants, offering power outputs between 60 and 115 horsepower. These engines were known for their reliability, fuel efficiency, and ease of maintenance, making the Astra a practical and affordable choice for everyday driving. The lightweight construction and front-wheel-drive layout meant the Astra was easy to handle, with good road manners and predictable cornering.
But the real star of the range was the Astra GTE, launched in 1985, which became one of the defining hot hatches of the 1980s. Powered by a 1.8-litre engine producing 115 horsepower, and later upgraded to a 2.0-litre 16-valve unit with 150 horsepower, the GTE could hit 0-60 mph in around 7 seconds, putting it firmly in the same league as the Volkswagen Golf GTI and Ford Escort XR3i. With sportier suspension, sharper steering, and aggressive bodywork, including the iconic digital dashboard, the GTE was Vauxhall’s ultimate statement in performance and technology at the time.
Inside, the Astra Mk2 featured a simple yet well-laid-out cabin, with comfortable seats, a practical dashboard, and good visibility. Higher-spec models included more advanced features for the era, such as electric windows, central locking, and even an optional trip computer. The Astra was designed to be easy to drive and live with, making it a go-to choice for families, commuters, and company car drivers alike.
The Mk2 Astra also had a strong motorsport presence, competing in rallying and touring car championships, where its lightweight chassis and punchy engines made it a serious contender. It proved that, despite being a practical family car, the Astra had true sporting potential when pushed to its limits.
By the time the Mk2 Astra was replaced by the Mk3 in 1991, it had become one of the best-selling cars of the decade, firmly establishing Vauxhall as one of the UK’s most dominant car brands.
Today, the Astra Mk2 is a rare sight, as most have succumbed to rust and years of hard use. However, enthusiasts still appreciate it for its simple mechanics, engaging driving dynamics, and iconic styling, especially in GTE form. The Mk2 Astra may have been a common car in its day, but it left a lasting legacy as one of the defining hatchbacks of the 1980s.
