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 Lancia Integralia rally car

Some cars are fast. Some cars are iconic. And then there’s the Lancia Delta Integrale, a car that didn’t just dominate rallying but changed the game entirely. Born in the fire and fury of Group A rallying, the Integrale wasn’t just Lancia’s answer to the competition, it was their declaration of war. This car didn’t just win. It destroyed the opposition, taking six consecutive World Rally Championships from 1987 to 1992, a record that still stands today.
But let’s rewind a bit. The Lancia Delta started life in 1979 as a front-wheel-drive hatchback, a perfectly sensible and stylish car designed by Giorgetto Giugiaro. It wasn’t built for motorsport, until Lancia decided it needed a four-wheel-drive weapon to replace the legendary 037 and the monstrous Delta S4. Enter the Delta HF 4WD in 1986, the first rally-prepped version that would lay the foundation for the Integrale dynasty.
By 1987, Lancia had refined the formula, introducing the Delta HF Integrale, a road-going homologation special that was essentially a rally car in disguise. It had a 2.0-litre turbocharged engine, four-wheel drive, and a chassis so perfectly set up for cornering that it felt like it could defy physics. With 185 horsepower in early models (eventually climbing to 215hp in the Evoluzione versions), it wasn’t the most powerful thing on the road, but it didn’t need to be. The real magic was in the handling. The Integrale could carve through corners at speeds that made supercars nervous. It had lightning-fast steering, perfect balance, and a chassis that seemed to read the road before you even turned the wheel.
And on the rally stage? It was unbeatable. From 1987 to 1992, the Integrale won six consecutive WRC manufacturer’s titles, with legendary drivers like Juha Kankkunen and Miki Biasion at the wheel. Whether it was snow, gravel, or tarmac, the Integrale just devoured every surface it touched. It could power through snow-covered Scandinavian forests one weekend and tear up the winding tarmac roads of Corsica the next, always coming out on top.
Lancia kept improving it. The 1989 Integrale 16V brought more power and better response, while the 1991 Integrale Evoluzione (Evo 1) widened the track, improved aerodynamics, and gave it that aggressive, wide-arch stance that made it look as fast as it was. By 1993, the final Evoluzione II model pushed out 215hp, added more refinements, and cemented the Integrale as one of the greatest homologation specials ever built.
But then, in 1992, Lancia pulled out of rallying. Their masterpiece had done its job. The Integrale had won everything there was to win, and rather than risk losing their streak, Lancia walked away at the top. It was a move that only added to the car’s mythical status.
Even today, the Delta Integrale remains one of the most beloved rally cars of all time. It’s not just about the numbers or the trophies, it’s about the feeling. Driving an Integrale is an event, a connection between machine and driver that modern cars just can’t replicate. The boost surge, the tight gear ratios, the way it grips and slides at the same time, it’s pure rally magic in road-going form.
Owning one today isn’t just about having a fast car. It’s about owning a piece of motorsport history, a car that represents the golden era of rallying, when manufacturers built cars to win championships first and sell them second. The Integrale isn’t just a classic, it’s one of the greatest performance cars ever made.
If you ever get the chance to drive one, take it. Because once you experience what an Integrale can do, you’ll never look at another hot hatch the same way again.
