Lightweight impact resistant racing windows

Experience the future of race car windows with polycarbonate—built for speed, strength, and serious track use.

With over 200 times the impact resistance of glass and about 30 times that of acrylic, polycarbonate gives you top-tier protection where it matters most. It handles heat better, insulates more effectively, and blocks UV like a champ—all while weighing far less than glass. That means easier installs, faster tweaks, and a car that responds quicker on race day.

And it’s not just for the track. Polycarbonate is trusted in construction, safety gear, and high-impact environments for a reason—it's built to last.

Whether you're chasing podiums or fine-tuning your weekend build, polycarbonate race windows give you the safety, performance, and flexibility to stay ahead.

Why RacePlastics Polycarbonate Windows?

Every Race Plastics window is made to order by our expert team in the UK. Built for motorsport, they deliver safety, strength, and serious weight savings—all in one piece of kit. Unlike Perspex and other acrylics, our polycarbonate windows are shatterproof and far tougher than glass, giving you the protection you need when you’re pushing hard.

We use 4mm polycarbonate as standard to meet key racing specs. Need more? We also offer 5mm FIA-compliant options and hard-coated upgrades for extra durability and scratch resistance.

Available in clear, bronze, or grey, you can choose the look that matches your build. Want sliders? You’ve got options—add one or both to the front doors to suit your setup.

Race Plastics gives you pro-level performance, custom fitment, and peace of mind when it counts.
