It may be necessary to replace the window guide rails with Teflon coated versions for a Honda / Acura NSX for several reasons, such as:
- Improved functionality: The original window guide rails on the NSX are made of thin aluminum, which can wear out over time, causing the windows to bind or become difficult to operate. Teflon-coated guide rails are more durable and can provide a smoother operation of the windows.
- Reduced friction: Teflon is a low-friction material, which can help to reduce the amount of wear on the guide rails and the windows. This can help to extend the lifespan of the guide rails and the windows, and improve the overall functionality of the windows.
- Increased resistance to wear and tear: The original plastic guide rails on the NSX are prone to wear and tear, especially if the car is driven in extreme temperatures, or if the windows are operated frequently. Teflon-coated guide rails are more resistant to wear and tear, which can help to extend the lifespan of the guide rails and improve their reliability.
- Increased resistance to corrosion: Teflon is also resistant to corrosion, which can help to extend the lifespan of the guide rails and improve their reliability.
- Aesthetics: Teflon-coated guide rails can be an upgrade over the factory parts, and can give a subtle touch of class and improved function to the vehicle.
It’s important to note that Teflon-coated guide rails are typically more expensive than the original plastic guide rails, and installing them may be more difficult and require more specialized tools and knowledge. It is recommended to consult with a professional mechanic or an experienced technician to determine if Teflon-coated guide rails are the best option for your specific vehicle and to ensure proper installation and function.
