I am thinking of making a subtle change to my build, going with a fiberglass rear bumper instead of the stock bumper. Since I need to replace the rear trunk support brace anyhow, I was wondering if I should replace it with the extra reinforcement pieces normally for the Convertible. The cost is negligible, only another $60ish worth of parts/brackets, and I will have a lot of work back there anyhow. I know the added structure means nothing for actually mounting the fiberglass bumper, but I was thinking in regards to extra structure in case of an accident or something. Any thoughts from you guys? Is this a good idea or pointless over building?
