Product Features
-
Aggressive M4 Sport Styling: Sharpens the side profile of your F3X 4-Series with the iconic sculpted aerodynamic contours and chiseled lower character lines inspired by the F82 M4.
-
Complete Rocker Molding Replacement: Designed as a full replacement assembly for the factory side skirts rather than tape-on covers, delivering a clean, flush, OEM-level finish along the door sills.
-
OEM-Grade Polypropylene Construction: Injection-molded from high-impact polypropylene (PP)—the identical material used by factory manufacturers—providing excellent flexibility, road debris resistance, and crack resistance.
-
Custom Finish Ready: Supplied in a smooth matte black finish that can be installed directly for a contrasting motorsport appearance, wrapped in vinyl, or prepped and painted to match factory BMW paint codes.
-
Precision F3X Digital Fitment: Molded from 3D laser scans of the F32/F33/F36 platform to ensure precise alignment along factory fender lines, door sills, and rear quarter panels across all 4-Series wheelbases.
-
Factory Mounting Point Integration: Built with OEM-spec clip channels and pre-formed underside mounting holes to utilize factory retainer pins and underbody chassis splash shields.
Installation
-

-

Direct replacement upgrade part; removal of the factory rocker panels and transfer or replacement of OEM plastic push pins and rocker sill clips is required for installation.
FAQ
Q1: Do these side skirts fit all 4-Series body styles including the 4-Door Gran Coupe (F36)?
A1: Yes; the F32 Coupe, F33 Convertible, and F36 Gran Coupe share the exact same wheelbase and rocker panel length, making these a direct fit across all three models.
Q2: Will these fit the actual BMW F82 / F83 M4 chassis?
A2: No; these are specifically engineered to give standard 4-Series models the aggressive M4 look; genuine M4 models have different front and rear quarter fender flare dimensions.
Q3: Are these add-on splitters or full rocker panel replacements?
A3: These are full replacement rocker molding panels that replace the entire factory side skirt assemblies.
