Replica seats could be made of Kevlar, I think that might be the Rotec reference another poster alluded to. That would definitely put them in the pricey range. But if they are simply Ebay replicas mounted onto some no name frame then they probably meet no racing standard, which imho are already pretty low for most inexpensive commercial racing seats -- not meant for daily driving because they would probably bend like Pepsi can in a real accident. I guess its like a novelty racing helmet (no certification) commemorating your favorite racing driver, might look nice on the book shelf but you probably wouldn't use it while in an actual car.
