HARD Motorsport Polycarbonate Rear Windows - PAIR - BMW E46 Coupe


Product Description


Abrasion resistant polycarbonate rear windows for your race car! A HUGE weight savings compared to the glass counter part. Provides excellent levels of protection against chemicals, UV yellowing, and hazing. This is NOT the cheap plastic garbage that will scratch when you clean or wipe down your windows from dust or a bit of moisture.


We use high quality 3M Performance Vinyl to give these replacement windows that O.E.M. factory look. Don't mess around with painting windows EVER again. 


As a gift from us, we'll even give you a pair of 2" custom driver/name decals!!  Great for your track build.

These come uninstalled, so you don't HAVE to put them on your windows. It's completely up to you. (Decals available in white vinyl only)


Just 2 lbs each! That's more than half of the original factory glass. (window motors and mechanism not included)


HARD Motorsport Window Mounting kit (recommended). Our slotted mounts will secure your windows directly to the existing vehicle window frame while correctly positioning against the outer weather seal for a better fitment and factory finished appearance.

Requires no modification or drilling! We give you everything you need. Our windows are designed to be used with this special hardware. Very clean and easily removable.
Want more weather resistance? Just add some peel-n-stick gasket material around your window frame!


If you run multiple drivers for special events or between run groups, a spare pair of windows can be used to change/display information, such as class and driver info. Throw another set of numbers on your second pair.

  1. E46 windows fit great! 5 Star Review

    Posted by on 26th Jun 2017

    Great product from HARD Motorsport once again. We used to hand make these at our shop (Vorshlag) but these are better looking and easier to install into an E46. Get the optional mounting kit, as it makes the install super easy. We dropped 7.6 pounds by replacing the glass rear side windows in an E46 coupe by going to these poly bits. 5 stars.

  2. So easy 5 Star Review

    For years I have made my own windows. Until now. For the price and how easy these are to install, hands down the best way to do it. Excellent material, great hardware and they look perfect. I added some foam material to waterproof the seal. Bam. Perfect!

  3. lightweight and fits great! 5 Star Review

    The polycarbonate rear windows for the BMW E46 are great quality, look OEM, and were installed with no problems. The hardware kit made installation a breeze. They fit perfect and look great too!
