Making every angle of your 3 series to look aggressive can be difficult. The front and rear may be easier than the sides. The M3 style side skirts can change that. These are made for the 3 series and will not fit/replace an M3.
These will fit all 3 series.
These come unpainted and will be a direct fit. No modifications needed.
Please have professionals install.
Select Optional - carbon fiber side skirt extension to finish the look. Please install with self tapping screws. (shown in pictures)
