Polycarbonate Window Kits

Polycarbonate windows have become a popular alternative to traditional glass windows in the racing industry, gaining traction mainly for their performance advantages. Odds are that you have come across these windows in one form or another, but why do racers prefer polycarbonate windows? Enhancing your BMW with polycarbonate windows can give you an edge on the track, providing crucial advantages over traditional glass. These benefits include:

1. Weight Reduction: Polycarbonate is considerably lighter than glass, reducing overall vehicle weight and lowering the center of gravity for improved handling and stability.
2. Superior Impact Strength: With its impressive impact resistance, polycarbonate will not shatter, increasing safety where crashes and collisions are a risk and complying with the stringent requirements of most racing series.
3. Durability: Polycarbonate is highly durable and can withstand the rigors of racing, including debris kicked up from the track and the stresses of high-speed driving.

To fully realize the performance and safety advantages of polycarbonate, extending its application to your rear windshield is essential:

• Weight Reduction Where It Matters Most: Reducing weight up high in the vehicle decreases its rotational inertia, allowing for quicker and more nimble handling characteristics.
• Performance & Safety: Reduces overall vehicle weight which is crucial for maximizing grip and traction, and meets track safety standards. 
• Customization: Our poly rear windshields can easily be cut and modified to fit the specific requirements of a racing car. For example, to route radiator ducting through the rear of the car.

Overall, the combination of lightweight, safety, and customization options makes rear polycarbonate windows an ideal choice for racing cars, where performance and safety are paramount.

Our polycarbonate window kits are easy to install, ensuring you can quickly upgrade your BMW with minimal hassle. Here are the basic installation tips (keep in mind every window has different specific install instructions):

1. Remove Old Glass: Safely remove the factory glass from the window channels and clean the area to prepare for the new installation. Sometimes the glass needs to be cut out, and sometimes it simply unbolts.
2. Preparing the Polycarbonate: You'll need to peel the protective plastic off the inside. Some windows have an inner channel separating the outer frame. Peel the plastic off and paint it black before peeling the rest off and installing it for that OEM look.
3. Installing Door Windows: Place the polycarbonate windows into the original window channels. For door windows, secure them with pins for easy removal. When dealing with permanent installations, the window will not roll down, but you can add a pass-through with our slider kit add-on.
4. Installing Rear Windshield & Quarter Windows: Use rivets, rivnuts, or factory seals for rear windshields and quarter windows to ensure a durable fit. Consider adding a NACA duct cutout for enhanced airflow through the flexible Neoprene Ducting, available as an additional feature.

With these simple tips, upgrading your BMW with polycarbonate windows is straightforward, ensuring you're back on track lighter and faster than ever before.
