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 MGC rally car

The MG MGC was meant to be the next big thing for MG. It was supposed to take everything people loved about the MGB and give it a serious injection of power, transforming it into a true British grand tourer. But as history shows, things didn’t quite go to plan. Launched in 1967, the MGC was a car with huge potential, but a mix of misunderstood handling, bad timing, and unfair comparisons meant it never quite got the respect it deserved.
On the surface, the MGC looked almost identical to the MGB, but under the bonnet, it was a completely different animal. Out went the familiar 1.8-litre four-cylinder, and in came a 3.0-litre inline-six. With 150 horsepower and a significant jump in torque, the MGC should have been a proper bruiser, capable of taking on the likes of the Austin-Healey 3000 and even giving Jaguar’s E-Type a reason to glance in the rear-view mirror.
The problem? That engine was big, heavy, and not particularly well-balanced for the MGB’s lightweight chassis. The front end had to be reworked to fit the larger block, resulting in a car that felt nose-heavy and didn’t have the nimble handling of the MGB. Early testers, including the press, were quick to criticise the steering and cornering, claiming it was slow and unresponsive compared to the lively MGB.
But here’s the thing, they were driving it wrong.
Unlike the MGB, which was built for sharp, playful handling, the MGC was designed as a high-speed grand tourer, a car meant for devouring miles rather than attacking hairpins. Once you adjusted to its driving style, the MGC was a seriously capable machine, with effortless cruising ability, loads of torque, and a refined ride that made long journeys a joy. It was smooth, powerful, and comfortable in a way the MGB never was.
It could hit 120 mph, making it one of the fastest MGs ever produced, and despite its extra weight, it could still hustle through the bends when driven with the right technique. Those who stuck with the MGC, particularly owners who figured out how to tune the suspension and adjust the tyre pressures correctly, discovered that the car’s handling wasn’t nearly as bad as the press had made it out to be. In fact, with minor tweaks, it could be a genuinely enjoyable GT car, fast, torquey, and surprisingly capable.
Unfortunately, the damage was already done. Sales were disappointing, and by 1969, just two years after launch, MG pulled the plug on the MGC. It never had the chance to properly prove itself, and for years it was dismissed as the MG that didn’t quite work.
But time has been kind to the MGC. Today, enthusiasts have re-evaluated its strengths, recognising it for what it was meant to be, a grand tourer, not a sports car. Properly set up, an MGC is a fantastic classic, offering smooth six-cylinder power, effortless long-distance cruising, and a character that sets it apart from the more common MGB. It’s rarer, more distinctive, and with modern suspension upgrades, it drives far better than people give it credit for.
Owning an MGC today isn’t just about having a classic, it’s about redeeming a misunderstood car, about appreciating what MG was trying to achieve, and about enjoying a car that offers the kind of relaxed, effortless motoring that modern cars can’t replicate. It may not have been the E-Type rival MG wanted, but in the right hands, it’s one of the best grand tourers they ever built.
