DMC Carbon Fiber Rear Diffuser

Bentley Continental GTC Convertible (2012–2018)

Power, when properly expressed, does not require exaggeration.

The Bentley Continental GTC Convertible embodies effortless performance — a grand tourer that moves with quiet authority. The DMC Carbon Fiber Rear Diffuser refines this authority with precision, introducing a motorsport-inspired architectural element that remains fully aligned with Bentley’s design language.

It does not shout.

It completes.

Sculpted Definition

The rear of the Continental GTC is broad, confident, and unmistakably Bentley. The DMC rear diffuser enhances this foundation by introducing structured depth beneath the bumper line, visually anchoring the vehicle to the road.

Its geometry is deliberate:

• Defined vertical fins for aerodynamic clarity

• Integrated alignment with factory exhaust outlets

• Proportions tailored specifically for the convertible chassis

From a distance, the silhouette becomes more purposeful.

Up close, the craftsmanship reveals itself.

Autoclave Carbon Fiber Construction

Each diffuser is produced using:

• Aerospace-grade carbon fiber

• Autoclave curing for structural integrity

• Lightweight reinforcement core

• Gloss or satin finish options

The carbon weave orientation follows the horizontal language of the rear bumper, maintaining visual continuity rather than contrast.

Every surface is measured.

Every angle intentional.

Functional Elegance

Beyond aesthetics, the diffuser subtly optimizes rear airflow by managing turbulence beneath the vehicle at higher speeds.

• Improved aerodynamic balance

• Enhanced rear-end composure

• Greater visual width and stability

The result is refinement without aggression — performance without spectacle.

Engineered for the 2012–2018 GTC Convertible

Unlike universal aftermarket solutions, the DMC diffuser is developed specifically for the Bentley Continental GTC Convertible (2012–2018) platform.

It respects:

• OEM exhaust configuration

Installation is precise and reversible, preserving the integrity and long-term value of the vehicle.

The Complete Sportisimo Expression

When paired with:

• The DMC Sportisimo Rear Wing

Where performance meets proportion.

Install:

This is an add-on part, the OEM rear trunk does not need to be removed for installation. Although fitting is quite straight forward we do always recommend using a trained professional to undertake the install. We estimate around 90 minutes to fit.

Gel Coat:

DMC Products come with a free Gloss or Matte Coating on all Carbon Fiber items, please leave a note at check out which one you like. If you don’t specify we will add a gloss base layer. However we suggest you to add one additional layer to match your country’s local UV and weather requirements as they differ throughout the world. We also suggest to wax, polish and seal the item further, even though we include a base seal of high quality carnauba product. This can be protective in regions that have high humidity or rain.
