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 MG MGB Roadster rally car

If there’s one car that perfectly embodies the spirit of classic British motoring, it’s the MGB Roadster. This wasn’t some exotic, high-priced supercar, it was a true driver’s car, designed to bring top-down thrills to the masses. Launched in 1962, the MGB Roadster quickly became one of the most popular sports cars of its era, loved for its simple, elegant design, engaging driving experience, and mechanical reliability. Whether cruising through the countryside, taking on a winding mountain pass, or just enjoying a summer’s day with the roof down, the MGB Roadster was built to make driving feel special.
When it arrived, the MGB represented a big step forward from its predecessor, the MGA. It had a monocoque construction, making it lighter, stiffer, and more refined than the traditional body-on-frame designs of earlier British roadsters. This not only improved handling but also made the car stronger and safer, something that wasn’t always a priority in 1960s sports cars. The styling was clean, understated, and unmistakably British, with long flowing lines, a purposeful stance, and just the right amount of chrome to give it character.
Under the bonnet sat a 1.8-litre four-cylinder engine, producing around 95 horsepower. It wasn’t about outright speed, the MGB was all about balance, handling, and fun behind the wheel. The lightweight chassis, rear-wheel-drive setup, and sharp steering made it an absolute joy to throw into corners, while the well-tuned suspension meant it was forgiving enough for everyday driving. It was a sports car that you could push hard without it biting back, making it perfect for both beginners and experienced drivers alike.
One of the MGB Roadster’s greatest strengths was its durability. Unlike many classic sports cars, which were often delicate and temperamental, the MGB was mechanically simple and built to last. It quickly earned a reputation as a reliable workhorse that could be driven daily, repaired easily, and enjoyed for years without breaking the bank. It was affordable, practical, and incredibly fun, making it the ideal entry-level sports car.
Beyond the road, the MGB Roadster also saw plenty of action in motorsport. From club racing to endurance events, it proved itself to be a capable and competitive machine, taking on much more powerful rivals and often holding its own. It wasn’t the quickest car on the grid, but its predictable handling and lightweight construction made it a favourite among privateer racers, many of whom still campaign them in historic racing today.
Of course, no conversation about the MGB Roadster is complete without mentioning the experience of driving one. Sitting low to the ground, gear lever in hand, wind in your hair, and the unmistakable rasp of the exhaust behind you, the MGB delivers something that modern cars struggle to replicate, a raw, mechanical connection between car and driver. There are no electronic aids, no fancy driver modes, just you, the road, and a car that wants to be driven.
Today, the MGB Roadster remains one of the most beloved classic cars in the world. Its timeless styling, engaging driving dynamics, and easy maintenance mean that it’s still a popular choice for classic car enthusiasts, collectors, and weekend drivers. Whether fully restored or slightly rough around the edges, an MGB always carries with it a sense of freedom, nostalgia, and pure driving joy.
Owning one isn’t just about having a classic sports car, it’s about keeping a piece of motoring history alive. It’s about the simple pleasure of driving for the sake of it, about taking the long way home just because you can, and about embracing the kind of motoring experience that modern cars have long since left behind. The MGB Roadster isn’t just a car, it’s a way of life.
