Similar to the E9X M3, BMW gave enthusiasts a head start with the elimination of the chrome window trim in favor of their gloss black "shadow line" trim. Unfortunately, BMW did not address the chrome front or side grills.
With BMW leaving off at the window trim we decided to pick up the pieces and offer a high quality painted solution for the F10 M5 community. All IND front grilles utilize the OEM part as a base to ensure a 100% fit. The original BMW chrome base does require a touch more preparation than if we had used an equivalent aftermarket part, but the end result is a product with perfect fitment.
