Most aggressive Diffuser on the market for the E92 M3!! Personally, we think it's probably the best looking addition to the already aggressive rear booty. However, it has so much functional benefits for anyone who loves driving! It's a must for all the Tracking junkies to get the most aerodynamic from your E9X M3!! Please note: this is only for the under tray and fins.
