Product information
Race Plastics polycarbonate windows are handcrafted to order by our expert UK team. Designed for motorsport and high-performance use, they’re lightweight, tough, and completely shatterproof—unlike glass or standard acrylics, which can crack under stress.
Our standard windows use 4mm polycarbonate to meet Motorsport UK regulations. We also offer 5mm options that are FIA compliant, plus hard-coated variants for added durability and resistance to scratching.
All windows are available in clear, bronze, or grey tint to suit your vehicle’s design. You can also add window sliders to either or both front doors, depending on your setup.
Window Sliders
Each slider kit is made from the same polycarbonate as your chosen windows. Designed for both driver and passenger sides, these sliders are reliable, practical, and easy to install.
Choose between:
- Three-position locking with a smooth, rattle-free action
- Simple two-position setup for fast and secure use
Sliders are engineered to avoid scratching and sit flush with your window kit. Ideal for improving airflow on track days or road builds. More info is available on our Window Slider Kits page.
Shipping times
Once your order’s confirmed, we’ll get started. Most standard orders are manufactured and dispatched within 3 weeks. Custom or hard-coated versions may take a little longer—we’ll contact you with a lead time. If you need your order by a specific date, let us know and we’ll aim to meet it.
Can I fit the windows myself?
Yes, installation is usually straightforward. There are helpful videos online, and our windows are designed to fit into standard rubber seals unless otherwise noted. If you need bolt-in variants, just contact us.
Can I collect my order?
Collection from our UK facility is available by arrangement. Most international orders are shipped, but we’re happy to sort collection if needed—just get in touch.
Want to change your order?
Reach out as early as possible. We’ll always try to accommodate changes, but if manufacturing has already started, there may be a charge.

The Ford Escort M5 Cosworth 2-door rally car
The Ford Escort RS Cosworth wasn’t just another hot hatch, it was a homologation special built with one purpose: to dominate rally stages and obliterate the competition. Launched in 1992, it carried the Escort name, but in reality, it was a Sierra Cosworth underneath, disguised in an Escort-shaped body. This was a no-nonsense, turbocharged, all-wheel-drive beast that brought Ford back into the World Rally Championship (WRC) spotlight, rekindling the brand’s legendary rally pedigree.
The Escort RS Cosworth was an engineer’s dream, blending rally-bred performance with road-going accessibility. At its core was the legendary 2.0L turbocharged Cosworth YBT engine, an evolution of the Sierra RS Cosworth’s YB unit. With 227 horsepower in road-going spec (and far more in race trim), it was a serious performance machine. The power delivery was savage, especially when the turbo spooled up, giving it that iconic old-school turbo lag followed by an explosive surge of acceleration.
Unlike previous Escorts, this one had all-wheel drive, a necessity for taking on the likes of Lancia, Subaru, and Mitsubishi in WRC. The drivetrain was 60% rear-biased, giving it the handling characteristics of a true performance car while still offering the grip and traction needed for rallying. The suspension was heavily revised, featuring race-inspired geometry, wider tracks, and upgraded dampers to keep it composed at high speeds and through tight corners.
But what truly made the Escort RS Cosworth unforgettable was its wild aerodynamics. That massive “whale tail” rear spoiler wasn’t just for show, it was functional, designed to provide high-speed stability and downforce. It became one of the most iconic features of any rally car of the 1990s, making the RS Cosworth instantly recognisable whether on a WRC stage or a city street.
In rallying, the Escort RS Cosworth was a force to be reckoned with. Entering competition in 1993 under Group A regulations, it quickly proved itself as a serious contender. While it never won a WRC title outright, it secured multiple wins and podiums, driven by some of the best in the sport, including Francois Delecour, Juha Kankkunen, and Tommi Mäkinen. It was fast, aggressive, and unrelenting on any surface, tarmac, gravel, or snow, it didn’t matter.
As rallying transitioned into the World Rally Car (WRC) era, the Escort RS Cosworth evolved, losing the whale tail in later versions but maintaining its brutal turbocharged power and all-wheel-drive grip. Even after its time in top-level rallying ended, it remained a favuorite in national and privateer rallying, proving just how capable its platform was.
On the road, the Escort RS Cosworth was one of the most exciting cars of its time. It wasn’t just fast in a straight line, it handled like a proper race car, with precise steering, immense grip, and a raw, mechanical feel that modern turbocharged performance cars often lack. It was a car that demanded respect, rewarding skilled drivers but punishing those who underestimated it.
Today, the Escort RS Cosworth is a legend. It represents the last of the true rally-derived Ford road cars, a machine built with WRC victory in mind rather than just meeting emissions regulations or appealing to mass-market buyers. Its values have skyrocketed, with enthusiasts and collectors recognising it as one of the greatest performance cars of the 1990s.
For those who were lucky enough to drive one, the Escort RS Cosworth wasn’t just a car, it was an experience. The turbo lag, the grip, the noise, the sheer aggression of the thing, it was pure, unfiltered performance, wrapped in a boxy 90s shell with a wing big enough to make a fighter jet jealous.
It might have been called an Escort, but this was no ordinary Ford. It was a Cosworth-bred, turbocharged, rally-winning legend, and it remains one of the greatest machines ever to wear the blue oval badge.
