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 Morgan Plus 4 rally car
The Morgan Plus 4 is a car that refuses to bow to modern trends. While other manufacturers chase cutting-edge technology and futuristic styling, Morgan has stayed true to its roots, crafting hand-built sports cars that celebrate traditional motoring. First introduced in 1950, the Plus 4 remains one of the most beloved classic British roadsters, blending old-school craftsmanship with just enough modern performance to keep things exciting.
At first glance, the Plus 4 looks like something straight out of the 1930s, a long bonnet, sweeping fenders, wire wheels, and a distinctive upright grille. It’s a design that has barely changed in decades, and that’s exactly the point. Morgan builds cars for those who appreciate heritage, craftsmanship, and the pure joy of driving, rather than those chasing the latest automotive trends.
Despite its vintage appearance, the Plus 4 has evolved under the skin. Early models were powered by a range of four-cylinder engines from Standard, Triumph, and Rover, but modern versions benefit from Ford-sourced 2.0-litre and 2.3-litre units, delivering up to 180 horsepower. In a car that weighs just over 1,000kg, that means plenty of performance, with brisk acceleration, sharp throttle response, and an addictive exhaust note that makes every drive feel special.
The driving experience is raw, engaging, and unfiltered. There’s no power steering, no electronic assists, just you, the car, and the road. The lightweight chassis, combined with a well-tuned suspension setup, makes the Plus 4 nimble and responsive, encouraging you to push it through the corners with confidence. It may not have the outright grip of a modern sports car, but what it offers instead is a pure mechanical connection between driver and machine, something that’s increasingly rare in today’s world of technology-packed cars.
The Plus 4 isn’t just about performance, it’s about the experience. The open-top motoring, the smell of leather and wood in the cabin, the way the car communicates every bump and ripple in the road, it all adds up to a driving experience that’s as much about emotion as it is about speed.
Inside, Morgan sticks to its handcrafted philosophy, with a cabin that’s a mix of leather, wood, and aluminium. Everything is hand-fitted, giving the car a unique character that feels more like a work of art than a production-line vehicle. The seats are snug, the dashboard is minimal, and the experience is deliberately analogue, reminding you of a time when driving was about skill and sensation, not touchscreens and driving modes.
The Morgan Plus 4 may not be the fastest, most technologically advanced roadster on the market, but that’s never been its goal. It’s a car for those who appreciate the romance of classic motoring, for those who want to enjoy every gear change, every bend in the road, and every moment behind the wheel.
For those looking for something unique, something handcrafted, and something that turns every drive into an event, the Plus 4 is a timeless choice, a car that proves that some things never go out of style.
