Polycarbonate Motorsport Windows, Kits & More
Since 1986
Welcome to RacePlastics
At Race Plastics, we build polycarbonate race car windows for serious drivers—whether you're tearing up local track days, building a weekend warrior, or running a full-spec competition car. With nearly 40 years in motorsport, we know what matters: performance, durability, and a precision fit that holds up under pressure.
Every window is custom-made in our UK facility, using advanced tech and hands-on race experience to deliver products that go the distance. From lightweight Lexan window kits for grassroots builds to full polycarbonate setups for pro-level machines, our glazing cuts weight, absorbs impact, and stays solid through every lap.
Swapping out glass? Replacing cracked panels? Our polycarbonate window kits are a smarter, lighter upgrade—track-tested, race-proven, and built to perform.

Polycarbonate Race Windows
We offer a full lineup of polycarbonate race car windows, including standard 4mm and FIA-approved 5mm options. Want a sharper look? Add a bronze tint upgrade for improved visibility and serious track style.
