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 BMW E30 2dr 3 Series Coupe rally car

If there’s one car that cemented BMW’s reputation for building ultimate driving machines, it’s the E30 3 Series. Launched in 1982, this was the car that took everything great about the E21 and turned it up to eleven. It had sharper handling, a more refined chassis, and, most importantly, it laid the groundwork for one of the most legendary racing machines ever, the E30 M3.
While the E30 was a solid performer straight off the showroom floor, its real magic was unlocked on the track and rally stages. This thing was a proper giant killer. Whether it was slicing through winding backroads or going full-send in the European Touring Car Championship, the E30 had a balance and feedback that made it a dream to drive. BMW’s engineers got the formula just right, rear-wheel drive, a near-perfect weight distribution, and a selection of engines that ranged from eager four-pots to the sweet-revving six-cylinder 325i.
And then there was the E30 M3. Homologated for Group A racing, this was the car that turned the 3 Series into a motorsport legend. Wide box arches, a high-revving 2.3L four-cylinder, and razor-sharp handling made it a dominant force in touring car racing throughout the late ‘80s and early ‘90s. It racked up wins everywhere, from the DTM to the BTCC, solidifying itself as one of the greatest performance cars of all time.
Rally teams weren’t about to let the E30’s potential go to waste either. The 325iX, with its all-wheel-drive system, became a favourite in rally circuits, taking on gravel and snow stages with surprising agility. While the E30 is usually remembered for its track dominance, it proved just as capable with a bit of dirt under its wheels. Privateer teams ran rear-wheel-drive 325is in rallying too, relying on the car’s beautifully balanced chassis and torquey straight-six to dance through the stages. It might not have had the turbo grunt of its AWD rivals, but in the right hands, it was a weapon.
What really makes the E30 special is how it blends raw, analogue driving with an everyday usability that few performance cars of its era could match. It wasn’t just a racer’s car, it was a car for everyone. Whether you were blasting through backroads, taking it to a track day, or just enjoying a weekend drive, the E30 made every journey feel like an event.
Even today, the E30 remains a favourite among enthusiasts and collectors. The M3 has become a six-figure legend, but even the standard 325i still commands respect as one of the most engaging driver’s cars ever built. If you see one out in the wild, chances are it’s being driven properly, because that’s exactly what the E30 was made for.
