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 Land Rover Discovery MK3 rally car
Some SUVs are built for the school run. Others, like the Land Rover Discovery Mk3, are built to climb mountains, cross deserts, and wade through rivers, and still be comfortable enough to take the family out for dinner afterward. Launched in 2004, the third-generation Discovery wasn’t just an update, it was a complete reinvention, a blend of rugged off-road toughness and modern luxury, making it one of the most capable and versatile 4x4s of its time.
From the outside, the Mk3 Discovery looked more refined and upmarket than its predecessors. It had a more squared-off, modern design, but don’t let that fool you, this was still very much a Land Rover underneath. The high ground clearance, short overhangs, and serious approach angles made sure it could still tackle rocky trails and muddy fields with ease. Whether in the urban jungle or the actual jungle, the Discovery felt right at home.
Under the bonnet, the Mk3 came with a choice of proper powerplants. The 4.4-litre Jaguar-sourced V8 was a smooth operator with plenty of grunt, but the real star was the 2.7-litre TDV6 diesel. It had torque for days, making it ideal for towing, off-roading, and long-haul adventures. Paired with a six-speed automatic or manual gearbox, it provided strong pulling power, solid reliability, and surprisingly decent fuel efficiency for a heavy 4x4.
But what really set the Mk3 apart was its technology. This wasn’t just a rugged off-roader, it was one of the most advanced SUVs of its era. Land Rover introduced the Terrain Response system, a game-changer for both experts and amateurs. With a simple dial, you could choose settings for mud, sand, snow, rocks, or tarmac, and the car would automatically adjust the suspension, traction, and throttle response to suit. It was like having an off-road driving instructor built into the dashboard.
The Discovery Mk3 also introduced an independent air suspension setup, which made it shockingly comfortable on the road while still providing superb articulation and ground clearance off-road. It was a true all-rounder, capable of tackling extreme terrain yet refined enough for long motorway drives without breaking a sweat.
Inside, it was built for adventure and luxury in equal measure. The three-row seating setup meant it could comfortably carry seven adults, and the cabin was solidly built, packed with premium materials, and filled with practical touches. There was enough space for luggage, gear, dogs, and everything in between. Whether you were heading to the Alps, the Outback, or just the local supermarket, the Discovery felt ready for anything.
In real-world use, the Discovery Mk3 became a legend among overlanders, farmers, and explorers. It was the kind of 4x4 that you could load up with camping gear, point towards the horizon, and just keep driving until the road ran out, because when it did, the Discovery wouldn’t care. It would just keep going.
Despite its off-road pedigree, the Discovery Mk3 was also a hit in the luxury SUV market, proving that a proper, go-anywhere 4x4 didn’t have to be rough around the edges. It could compete with the BMW X5 and Mercedes ML-Class in comfort while leaving them for dead the moment the road turned into a trail.
Today, the Discovery Mk3 is still a favourite among Land Rover enthusiasts, known for its uncompromising off-road ability, solid build, and timeless design. It’s not the cheapest SUV to maintain, but for those who love proper 4x4s, there’s still nothing quite like it.
If you ever get behind the wheel of one, don’t be surprised if you suddenly feel the urge to drive across a continent. Because that’s what the Discovery Mk3 was made for. Adventure. Anywhere, anytime.
