Maxton Design BMW 1 Series F20 F21 LCI M-Power Rear Valance Diffuser

Description

A rear valance diffuser for the facelift (LCI) F20/F21 M-Sport that finishes the back end to match an aftermarket exhaust and aggressive front splitter. Deep fins and a stepped centre section give the rear the width and menace the standard M-Sport bumper leaves on the table.

Features

Material

• Moulded from ABS plastic developed specifically for the automotive industry.
• The same class of material used for factory bumpers and OEM body trim.
• Strong yet flexible — built to survive kerbs, speed bumps and daily driving.

Finish Options

• Textured
• Gloss Black
• Carbon Look

Please Note

• Moulded from automotive-grade ABS — the material is designed to flex and take normal road pressure without cracking.
• Professional installation is recommended. Test-fit before bonding and clean the mating surface thoroughly for the 3M tape to key properly.
• Each part carries a Maxton holographic authenticity sticker. Removing it voids returns — it’s what identifies the part as genuine, so peel at your own risk.
