Supposedly Unlimited's quality has improved after being bought out. They do Carbon fiber and Carbon/Glass also. That being said the only thing I have purchased form them is a bumper inlet for a ProCharger in Carbon. The quality was good. You don't say if your looking for race weight or street style replacement pieces. GlassTek quality is good. I have a US body source front bumper and bolt on hood for a 63 Dodge Polara and the quality is good but they are both heavy.
