Will this fit my M-Sport or custom front bumper?

This trim is designed for factory F30/F31 bumper geometry. If you're running a significantly modified or aftermarket bumper, verify fitment with your bumper supplier before ordering — gaps and alignment may differ from stock.

Do I need to remove my bumper to install this?

No. This bolts to factory attachment points behind the bumper fascia. You'll need to access those points, which typically requires removing or slightly loosening the bumper fascia — standard dealer-level work.

What prep and paint process do you recommend?

Refer to your preferred paint shop. Trim arrives unprimed — they'll handle surface prep, primer, and topcoat. If DIY painting, follow standard automotive panel procedure: sand to bare plastic, apply self-etching primer, then your choice of paint and clear.
