BMW M3/M4 2021-BMW G82/G83 M4 2021-Performance Style Dry Carbon Fiber Rear Diffuser

This product is made perfectly to fit a BMW G82/G83 M4 2021-Present, this is a replacement part, to install remove the gloss black diffuser from the rear bumper, press the tabs on the inside of the bumper where it is holding the OEM diffuser in place after removing the 10mm bolts from underneath. The trickiest part of the process is probably removing the rear diffuser as it does require patience, installing the replacement part is the easier process, by looking at the replacement part it will also help understand on where all the OEM clips are as the fitment is exactly the same, therefore reinstall will be the same process in reverse.
