I have yet to see an aftermarket cf door that had the beams. I think they all just assume you're going to get a race cage.

 

No after market carbon fiber doors have impact bars in them, with the exception being if any OEM manufacturers offer some sort of special edition replacement (there are none that I am aware of at this time).

Again these doors are not for road use, they are strictly for track prepped race cars that only have doors installed for the sake of aerodynamics and the ability to get in and out of the car.

 

Pete: I agree that carbon fibre does not "shatter" in the traditional sense. However, what it will do is splinter. I've seen it personally many times in actual testing.
