For OEM, ABS Plastic is king. but for aftermarket, PolyUrethane is the best. of course, there is always carbon fiber...the real deal...

Do you really think that CF is the best? Besides the weight savings and looks it is going to perform more or less like fiberglass. If you run into something CF is going to crack. I highly doubt that any aftermarket CF is autoclaved.

why do you say fiberglass is bad? Maybe if it's manufactured or designed poorly it's bad, but that isn't a very good generalization. I'm a design engineer and design fiberglass/SMC/RTM/etc body panels and structural parts for the auto industry---and fiberglass is not "bad" for A-surface parts.

I agree with Dre325 fiberglass can be just fine. The complaint that most people don't like about fiberglass for a kit is that it does not flex like a plastic. Bump into something and you could crack a fiberglass kit.
