does anyone now where to get a fiberglass or carbon fiber hood for our cars thanks for any help finding these products

Accidentally found this while doing a Google Search on Roush and Conquest... http://www.super-happy-shopper.com/ratings...cowl_hoods.html    

This site will not have quest specific parts but for those parts that are common to most imports are available at great prices and NO charge for packaging, handling or shipping! Mark

I'm looking to get front coil springs but im noticing that there are 3 types available at the dealers for our cars. I see standard and sport springs for about $69 and a heavy duty spring for about $95. Which one is advisable for a daily driver car?? Or should i stay away from them?? Any comments/feedback/recommendations are greatly appreciated.   Thanks.
