With Dinan's carbon fiber kidney grille surrounds, one of the most iconic elements of your BMW can be transformed into something even more special. Built for easy installation, the carbon fiber kidney grille surrounds utilize the same locking tabs the factory parts use for a seamless and clean installation. NOTE: What is being sold are ONLY the kidney grille surrounds. The center vertical slat section will be re-used (chrome slats in the case of a stock vehicle) from the stock component. For best appearance, we recommend using the black M performance grilles to complete the look. That would consist of Dinan part number D980-0015 for the M4 or D980-0020 for the M3. Alternatively, BMW Part # 51-71-2-352-812 (M3 & M4 Right Grille) and 51-71-2-352-813 (M3 Left Grille) or 51-71-2-352-811 (M4 Left grille) can be acquired through any BMW parts counter or at various online stores.
