Description
Sharpen the rear profile of your Mercedes C Class & C63 Sedan with the Carbon Fibre Rear Diffuser from FORM. Combining aerodynamic function with aggressive styling, this diffuser bolts directly in place of the factory unit for a clean OEM+ finish.
Key Features:
- Direct OEM fitment — retains factory mounting points, wiring connectors, and sensor cut-outs where applicable
- Direct-fit replacement for the OEM lower rear bumper section
- Improves underbody air extraction for reduced rear lift and improved stability
- Aggressive vertical fins add visual width and motorsport presence
- Lightweight carbon fibre construction with a UV-protected gloss clear coat
- Backed by FORM Industries — a trusted name in OEM-level aftermarket upgrades for modern performance cars
Construction: Produced in quality carbon fibre and finished with a protective clear coat to keep the weave bright, consistent, and resistant to UV fade over the long term.
Fitment: This product is designed specifically for the Mercedes C Class & C63 Sedan, model years 2015-2019, W205. It integrates with the factory panel lines, mounting points, and (where applicable) electronic systems, meaning no cutting, drilling, or bodywork modification is required for a standard install. Please double-check your chassis code against the listed fitment before ordering — if you're unsure, our support team is happy to confirm compatibility for your exact vehicle.
Installation: Fitment is straightforward for an experienced installer using standard hand tools. We strongly recommend installation by a qualified bodyshop or detailer, particularly for exterior components that require panel alignment, adhesive bonding, or painted-surface preparation. Full fitment guidance is provided in the box, and our support team can help confirm the best approach for your specific car.
The FORM Industries Difference: Where many aftermarket brands compete on price, FORM competes on fit and finish. Every part in the catalogue is developed on real cars — not just in CAD — with panel-gap tolerances, material selection, and finishing processes benchmarked against the OEM part it replaces. It's why FORM has become one of the go-to names for BMW M, Audi RS, and Porsche GT owners looking for an upgrade that genuinely measures up.
