Rieger Rear Bumper Diffuser for BMW 1 Series M135i F20/F21 Pre-LCI (2011-2015) - Direct Replacement OEM Fit ABS - Matte/Gloss/Carbon Look - Made in Germany

Rieger Rear Lower Valance Insert for BMW 1 Series M135i F20 F21 Pre-Facelift 2011 to 2015

Give the back end of your M135i the premium German styling it deserves with this genuine Rieger rear lower bumper insert. Purpose built for the BMW 1 Series F20 and F21 M135i pre-facelift models, it replaces the standard lower panel for a tighter, more aggressive OEM-plus look with factory-quality alignment. Manufactured in Germany from robust ABS, this upgrade delivers a performance-focused finish without compromising everyday usability.

We have installed these for customers at MJ Modifications and the feedback has been outstanding. Fitment is precise, the silhouette is sharper and the quality feels every bit as premium as the original equipment. If you want a subtle motorsport aesthetic with zero drama, this is the right piece of kit.
