A red LED light in the centre of the diffuser adds a race-inspired rear signature.

Deep Aero Fins

Sculpted fins across the diffuser channel airflow and add depth to the rear bumper.

Matching Side Splitters

Carbon splitters extend the lower corners of the rear bumper for a wider, more aggressive stance.

Vehicle Fitment

Mercedes-AMG CLA45 (C117, 2013-2019)
