Lexan Car Windows

Boost Your Performance with Lexan Race Car Windows

Get the edge on American tracks with Lexan polycarbonate windows. For serious US racers, every detail counts, especially when it comes to performance and safety. Lexan windows are engineered to handle the extreme demands of motorsport, combining lightweight durability with crystal-clear visibility. Whether you're competing in SCCA, dirt oval, drag, or track day events, Lexan gives you the speed, protection, and peace of mind to push harder.

What are Lexan Polycarbonate Windows?

Lexan is a high-performance polycarbonate material that’s built to outperform traditional glass. Where glass can crack or shatter under pressure, Lexan flexes, absorbs impact, and keeps going. It’s used across motorsport for its combination of strength, clarity, and heat resistance—making it ideal for track cars where safety and visibility are non-negotiable.

Why Use Lexan?

Lexan doesn’t just replace glass—it improves on it:

Impact strength:

Around 250 times stronger than glass and designed to withstand flying debris and contact.

Weight savings:

Lighter than glass, reducing your car’s weight and improving acceleration and handling.

Heat resistance:

Performs across a wide temperature range, from cold starts to blazing-hot track days.

Optical clarity:

Keeps your view sharp and clear even after serious mileage.

Formability:

Can be cold-formed to fit your car’s specific shape, ensuring a flush, aerodynamic finish.

Lexan isn’t just glass—it’s far superior. Whether you're dealing with flying debris, extreme weather conditions, or the heat of the race, Lexan windows are built to take it all in stride, withstanding impact and environmental challenges that would shatter ordinary glass.

Lexan vs Other Brands

You’ll see names like Makrolon and Arla in the polycarbonate space too. All three are premium-grade, motorsport-suitable options. Lexan is often chosen in the US for its availability and trusted performance. That said, RacePlastics can source and work with any top-tier brand you specify.
