Maxton Design Piano Gloss Sill Extensions for BMW E46 3 Series Coupe 1999-2003 M-Technic

Give your E46 Coupe a sharper, lower and more purposeful look with these Maxton Design side extensions in deep piano gloss. Designed for the BMW 3 Series E46 two-door with the M-Technic package, these rocker panel add-ons visually lengthen the chassis line, tidy the side profile and tie in perfectly with front lips and rear diffusers for a cohesive factory-plus finish.

Built from durable ABS, these side blades are light, tough and styled to complement the E46 silhouette. The high gloss surface matches other Maxton aero parts and looks brilliant on all paint colours. We have fitted these on customer cars and the feedback on fit and finish has been excellent.
