My guess is it is very similar to FRP but instead of splinterd fiberglass it is the fiberglass cloth.

FRP backing


Fiberglass woven cloth

I've held the bumper and carried the bumper when I brought it home. It flexes like a PU bumper but not as much as PP (polypropylene) which flexes as much more due to the material. It is NOT as hard and stuff as fiberglass.

I don't think I have seen an aftermarket shop that doesn't have at least one bad review. They have a bad rep in the e92 m3 forum, yet so many people run the Arkym CF diffuser on their e92 335s. You can't expect the same result in a different forum and chAssis.

Sometimes shops are stuck at the mercy of the manufacturer.

Just my 2 cents.

Dunno how much you read on that thread. But the post is a joke since the guy refused to return a hood for refund. He thinks that he should be issued a full refund without returning a hood. Not sure who's right and wrong here.

lol, I am just surprised I couldn't find it. I am merely curious, I have dealt with a few different composites and even have a pMMA keychain I made back in my undergrad days. PWC seems fishy to me because its name doesn't signify its contents(what the composite material is). Woven is interesting to me because if memory serves you want to maintain the same thread directions for best resistance to tension(for that same direction of course), but its not like these bumpers will get pulled on. I would think the biggest importance for these bumper would be heat(for deformation, some plastics/polymers would deform around surrounding materials under significant heat (thermoelasticity)), hardness, and resistance to discoloration. But with an ambiguous name like PWC, I can't qualitatively say if it is a good material.

As I said earlier, not looking to bash, just merely curious what it is made out of. I am not a materials science expert, it's not my field of study. Other thing that is interesting is I can't find any weight numbers(especially vs. stock).

Good to know. I'd definitely like to see it in person.

And for what it's worth, my experience with PY has been nothing but positive.
