Your BMW hoods are a very fashionable part of your car's exterior. They have their own separate contours, body breaks and body lines. Hoods are large and cover a lot of area. Their main purpose is to protect the engine from outside elements. However, sometimes other factors were left out when they design a BMW hood. New hoods have been developed to protect just as well, but save you the added weight.
Aftermarket hoods are typically not as heavy, come in a variety of styles and use the same mounting points as factory hoods. A fiberglass BMW hood weighs only a couple of pounds and can be finished in your OEM color. Custom projects tend to have custom Bimmer parts. More and more owners are learning that weight reduction helps in all aspects of driving including performance and increasing your MPG. Fiberglass BMW hoods are a great alternative to the stock hoods that can weigh in excess of 100 pounds!
Another great option that has emerged in recent years is the BMW carbon fiber hood. They are constructed of heavy duty carbon fiber and are incredibly strong. They come in the gray / black styling because that's the way carbon fiber is made, but they can be painted to match the rest of your car like other custom BMW exterior parts.
