Product information

Every Race Plastics window is custom-made by our experienced team in the UK. Built for motorsport, these polycarbonate windows are lightweight, shatterproof, and far stronger than glass. Unlike acrylics or Perspex, they won’t crack under pressure—giving you peace of mind when you’re pushing hard.

Our standard spec uses 4mm thick polycarbonate, meeting key racing regulations. If you need more strength, we also offer 5mm FIA-compliant windows and hard-coated options for extra durability and scratch resistance.

Windows come in clear, bronze, or grey tints, so you can match the look to your build. You can also add sliders to either or both front doors, depending on how you want to manage airflow.

Window Sliders

Our slider kits are built from the same high-quality polycarbonate as your main windows. Designed for both driver and passenger sides, they’re smooth, secure, and built to last.

You can choose between:

  • Smooth operation with three fixed positions, no rattle
  • Simple and reliable, with two preset stops

Easy to fit and made to avoid rubbing or scratches, these sliders are ideal whether you need more air on track or better control on the road. For full specs, visit the Window Slider Kits page.

How long does shipping take?

We’ll confirm your order right away. Standard polycarbonate kits are usually built and shipped within 3 weeks. Custom or hard-coated orders may take longer—we’ll reach out to confirm the lead time. If you’ve got a race coming up, let us know and we’ll do what we can to hit your timeline.

Can I install the windows myself?

Yes. Most builds are straightforward and there are plenty of how-to videos online. Unless stated otherwise, our windows are made to fit into standard rubber seals. Need bolt-in versions? Just reach out.

Can I pick up my order?

We usually ship via courier, but yes—collection from our Leeds facility can be arranged. Just drop us a message.

Need to change your order?

Get in touch as soon as you can. We’ll do our best to make changes, but if production’s already started, there may be a cost to amend the order.

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.
