Overview
The Mercedes-Benz CLS Class W218 is an icon of understated luxury and dynamic design. From 2011 through 2019, both the CLS350 and the thunderous CLS63 AMG set the standard for four-door coupé elegance. Yet the factory rear end, while refined, often leaves enthusiasts wanting more visual aggression and performance presence.
This CAARFAC CLS Class Carbon Fibre Rear Lip Diffuser Spoiler transforms that space with purpose-built aerodynamics and authentic material quality. Real carbon fibre construction paired with premium stainless steel quad exhaust tips delivers the aggressive stance your CLS deserves—without the questionable replica aesthetic of lesser alternatives. Every screw attachment is engineered for clean fitment across the full W218 generation.
Whether you're driving a measured CLS350 or the high-octane CLS63 AMG, this diffuser sharpens your vehicle's rear profile, improves downforce, and signals intent. It's the finishing touch that separates owned cars from cars that own their drivers.
