Mercedes CLS63 AMG W218 RENN Style Forged Carbon Rear Diffuser

Transform the rear end of your Mercedes CLS63 AMG with this aggressive RENN Style Forged Carbon Rear Diffuser. Crafted from premium forged carbon fibre — the same exotic material used by Lamborghini and McLaren — this diffuser delivers a bold, high-performance aesthetic that sets your CLS apart from standard carbon weave alternatives. Designed as a direct replacement for the factory plastic diffuser, it fits cleanly without permanent modification.

Forged carbon fibre is renowned for its distinctive marbled, multidirectional fibre pattern, offering superior strength-to-weight ratio alongside an unmistakable premium appearance. Each piece is hand-laid, finished with a high-clarity UV-resistant lacquer, and inspected before dispatch.

Vehicle Compatibility

Forged Carbon vs Standard Carbon Fibre

Forged Carbon is produced using a compression-moulded process with chopped carbon fibre strands, resulting in a distinctive marbled, swirling pattern unique to each piece. It is structurally stronger than standard woven carbon in many applications, offers greater design flexibility, and carries an exclusive premium appearance. Used by Lamborghini on the Aventador and by McLaren on special edition vehicles, forged carbon commands a higher specification than conventional 2x2 twill weave panels.

Installation

Installation requires removal of the rear bumper assembly for correct fitment. The diffuser locates into OEM mounting positions and requires no drilling or permanent body modification. Due to the complexity of rear bumper removal, we strongly recommend professional installation at a qualified bodyshop or AMG specialist.
