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 Beta Coupe rally car
Lancia has a habit of building cars that punch well above their weight, and the Lancia Beta Coupé was no exception. Born in the mid-1970s, it arrived at a time when Italian sports cars were either breathtakingly expensive or ridiculously unreliable, and sometimes both. The Beta Coupé was supposed to change that. It was affordable, stylish, and packed with the kind of sharp handling that made every drive feel like a tarmac rally stage.
Based on the Lancia Beta saloon, the Coupé was smaller, lighter, and much sportier. It had a shorter wheelbase, a lower stance, and an unmistakably Italian design, sleek, elegant, and with just the right amount of aggression. It wasn’t a full-blown exotic, but it looked and felt special, like something that could easily have worn an Alfa Romeo badge instead.
Under the bonnet, the Beta Coupé packed a range of Fiat-derived twin-cam engines, starting from a 1.3-litre unit and going up to a punchy 2.0-litre version. Power ranged from 80 to 120 horsepower, which doesn’t sound like much today, but with the Beta Coupé’s lightweight body, razor-sharp steering, and perfectly tuned suspension, it was more than enough to keep things exciting. This was a driver’s car, not just a fast one. The balance was spot on, the front-wheel-drive setup felt alive, and the Beta had a way of tucking into corners like a well-trained rally car.
Speaking of rallying, Lancia knew their way around the sport, and while the Beta Coupé never saw the same kind of success as the Stratos or the Delta, it did get its moment in the spotlight. The Lancia Beta Coupé 1800 ran in Group 4 rallying, and while it wasn’t as wild as its mid-engine Stratos sibling, it was a seriously capable machine on tarmac rallies, making use of its excellent chassis balance and rev-happy engine to keep up with more powerful competitors.
Then came the Lancia Beta Montecarlo, an offshoot of the Beta Coupé that took things to another level. With a mid-engine layout and a Pininfarina-designed body, it looked the part of a true exotic, and it even found success in Group 5 racing, where it helped Lancia claim a World Championship for Makes title in 1980 and 1981.
But for all its brilliance, the Beta Coupé’s reputation took a hit thanks to one infamous issue, rust. British models, in particular, were plagued with corrosion problems, which led to headlines that tarnished the Beta’s name and even saw Lancia recall and buy back some models in the UK. It was an unfair end for what was otherwise a brilliantly engineered and hugely enjoyable car, but in the court of public opinion, the damage was done.
Today, the Beta Coupé is a rare sight, but for those who know, it’s still one of the most underrated Italian sports cars of its era. It had the soul of a rally car, the handling of a proper sports coupe, and the kind of charisma that only an Italian car can deliver. If you find one today that hasn’t been eaten by rust, you’ve got yourself a hidden gem, a car that proves Lancia could make magic happen, even when the odds were stacked against them.
