some of the cheap places for bumpers roll them up for shipping and/or storage so dont be surprised if it takes a while for it to regain its shape after you get it stretched out. you will also have some fitting issues as the aftermarket covers arrr a little different dimensions, i think so it doesnt fall under gm's patent. it will fit but its gona take some work. lucky its not winter so the plastic should be a little softer.

When it came today the box was bigger than I was. The bumper is just as long as it would be when on the camaro. Is this not how they normally are shipped?

no they normally fold them up to make it take up less space (more space = higher shipping costs) you got lucky

The reason aftermarket parts do not fit correctly is money. A molded part does not alway react the way you want it. They shrink and twist all over the place.
Here in the US we have tons of software to help predict shrinkage but even then there will be some tweaking. This tweaking costs and the equipment to prove the part is right is also costly. When we quote a mold we normally add in 20-40% of the cost for "tweaking the tool". Once the mold is giving good parts and the customer (in this case GM) is happy the mold gets scaned on a scaning CMM. Anytime thru the life of the project the mold can be inspected and even remade to its original specs. Those specs are what GM will not give up.
Most likely this mold was made in Twain, It seems to be a hot spot right now for making large molds. Someone took the dimension off a few cars designed a mold and it is what it is. Since they do not have the money, equipment or a big customer to make happy it is good enough. Its the same way with the body pannel stampings. I have seen a pretty steady increase in accuracy of these "Knock off molds" the boys over in Twain are getting better.

Compare materials -- the OEM vs. that one -- I guarantee they are different materials. Biggest issue you might have is how well it fits. But for budget parts they are a bargain -- just don't expect perfection.

No doubt, just looking for someone to paint it at the moment then it will be going on my baby. It will be nice to get the bra off of her.
