N15 spent countless hours perfecting the shape and selecting the right material to achieve a good fitment. It isn’t easy designing flat sheet metal to conform to a compound curve, but they achieved it. During testing, their data acquisition systems showed an average increase of .1G in high speed braking zones. Reduces drag and increases front downforce Form fitting design that integrates with the body lines of the E46 M3 Easy DIY installation Instructions, cutting templates, and installation hardware included 42 sq. inches per side. *The vents ship flat and can be bent to shape by hand (installation instructions will show you how).
