CF doors by Carbon Microsystem

[bigjae46]

Have the windows been tested at speed? Lexan is not nearly as stiff as glass and it could be horribly annoying for street driving. And are the windows coated? Lexan will haze up over time due to scratching. Especially putting it up and down and having dust and dirt along the window seal.

a hatch too!!!!

U guys are really making me want an e46 touring just for the parts alone

[Obioban]

Very curious to see the weight difference for that! It might even need weaker hatch shocks.

On my CSL trunk, I run only one of the two struts for just that reason.

The rear hatch for the E46 Touring is almost ready.

Lexan Windows are Now at Carbon Microsystem!

We are excited to announce the expansion of our product range and the launch of our own production of Lexan (polycarbonate) windows, perfectly suited for our carbon fiber doors and beyond!

We stepped slightly away from our main focus to offer you another ideal solution for weight reduction and increased safety:

Each window weighs just 2.1 kg, which is more than half the weight of a standard window (4.5 kg)! This is a significant boost to your car's dynamics.

Every window is cut on a high-precision CNC machine according to a ready-made template, guaranteeing a perfect shape. After cutting, we process the edges and apply the necessary curvature to ensure a flawless fit.

Thanks to their incredible strength and flexibility, Lexan windows are ideal for motorsport, but they can also be used on daily driven cars.

Available for Order: BMW E46 and E92

These are not carbon doors, but we will add some variety to the forum feed.

Definitely putting some of these on my E46 when I have time. A shop local to me uses and sells these doors and says the fitment is incredible.

25 per door? or total?

... either way, that's some serious weight savings

25lb per door. My gutted door (no crash bar) was 35.5lbs. Yes, significant savings. The door skin metal seems to be quite thick. Maybe 14ga steel?

Gotta say... I really have the wants for some coupe doors with crash bars 😝

Fully dressed (door cards, windows, speakers, etc)-- how much weight saving are they worth? As in, what's the weight difference between a steel door and a crash bar carbon door, all else equal?

Weight of metal door with metal crash bars = 15.4kg (This is a completely empty door.)

[Slideways]

It was a 25lb difference between a gutted steel door and my carbon door which had about the same amount of material missing. My carbon door was about 11lbs with hinges, aftermarket latch, and an eBay racing mirror. My door could have been lighter but didn't want to risk it. The steel door is a heavy SOB.

The great thing about carbon doors is no door dings!

Next, can we get you to stand on your carbon roof 😁
