Unlike the older WRX, which had a lightweight aluminum hood, the 2008+ car has a hood made of STEEL. It weighs a ton! (Okay, not a ton, but over 40 pounds.) So there's a serious opportunity to take about 22 pounds off the nose of the car, and lower the center of gravity, by installing a lightweight carbon version.
Like all Seibon hoods, this one uses all the factory mounting points, including the factory latch. But we do suggest hood pins on any aftermarket hood.
