Air outtake splitter for front fender Mansory Carbon for Rolls-Royce Dawn

Air Outtake Splitter (Front Fender) — Mansory Carbon Dawn

The Mansory carbon air-outtake splitter for the front fender is a small but defining detail in the coachbuilt drophead — a sculpted carbon fin set that nests inside the front-fender air outlet, immediately aft of the wheel arch. Its job is two-fold: it accelerates the egress of hot air leaving the engine bay and the wheel-arch cavity, and it gives the Mansory carbon fender its finished, jewel-like character. On the 6.6-litre twin-turbocharged V12 Rolls-Royce Dawn — a fabric-roof, coach-doored two-door drophead — anything that helps vent intercooler-warmed underhood air is welcome, but the splitter is just as much a piece of theatre as it is an aero element. It is fitted as part of the wider Mansory Body Kit for Rolls-Royce Dawn, sitting in visual conversation with the Spirit of Ecstasy and the Pantheon grille that frame the bonnet line.

Construction & Materials

Each splitter set is laid up by hand from aerospace-grade prepreg carbon and cured in autoclave under controlled pressure. The result is a piece that stands up to bonnet-line heat, road-spray and decades of UV — Mansory builds these to live next to a Rolls-Royce coachwork panel, not to look like an aftermarket clip-on. The fin profile is shaped so the trailing edge sheds airflow cleanly, while the visible faces remain mirror-perfect under deep-gloss lacquer.

The splitter is engineered as a precision insert into the OEM Dawn front-fender outtake: it locates on the original mounting bosses, retains the cast Rolls-Royce surround, and uses concealed stainless hardware so nothing breaks the visual line.

• Weave: 3K twill carbon, optional 2K plain or forged-look on bespoke request
• Cure: autoclave-cured prepreg, post-cure dimensional check against master jig
• Wall thickness: ~1.6–2.0 mm at the visible faces, ribbed internally for fin rigidity
• Weight: ~0.35–0.55 kg per side depending on fin count and thickness
• Hardware: stainless concealed clips and a low-profile structural adhesive bead at the carrier
• Finish: Mansory deep-gloss two-pack lacquer matched to the rest of the carbon programme; satin and raw-weave available on request
• Edge treatment: machined, hand-flatted, lacquer rolled over the chamfer to seal the carbon edge
• Colour-keyed paint break: optional body-colour body, lacquered carbon fins — common on bespoke RR coachwork specs

Design & Visual Function

Visually, the splitter does what only a Mansory detail can: it turns a flat, un-styled OEM vent into a piece of architecture. The fins draw the eye along the front fender, lengthen the apparent dash-to-axle ratio, and provide a horizontal counterpoint to the verticals of the Pantheon grille. On a Black Badge car finished in shadow chrome, the lacquered weave reads as a deep, three-dimensional graphite — calm at rest, alive when the car moves under street lighting.

Functionally, the geometry is tuned to extract air rather than to redirect it. The wheel-arch zone of the Dawn carries hot air shed by the brakes, the front intercooler exchangers and the engine bay; that air wants to leave through the path of least resistance. The splitter's fin angles widen the effective exit area, smoothing the transition between the high-pressure pocket inside the arch and the low-pressure flow running along the flank toward the side skirt. The contribution is modest — Dawn is no track car — but on long fast-touring stretches it nudges underhood temperatures the right way, which is a kindness to a 6.6-litre twin-turbo V12.

From a coachbuilt perspective, the splitter is also where Mansory chooses to declare itself quietly. It does not shout. It is the kind of detail an owner notices walking up to the car at a hotel forecourt at twilight — the soft top down, Starlight ambient illumination glowing on the headliner inside, and the lacquered carbon fender outlet catching the porte-cochère light.

Compatibility & Fitment

Designed for the Rolls-Royce Dawn (model years 2015–2023), Standard and Black Badge, in all factory paint specifications. Drophead convertible only — Dawn does not exist as a coupé. The part respects every Dawn-specific package: it does not interfere with the soft-top stowage path, the rear-hinged coach-door geometry, the Spirit of Ecstasy retraction, or the optional illuminated bonnet pinstripe. OEM front-fender markers, side-repeaters and any factory parking-aid wiring are retained without modification.

Although the Dawn shares its underpinnings with Wraith, the front-fender outtake geometry differs subtly between cars and the splitter is not a drop-in fit for Wraith. Owners commissioning a matched two-car spec should plan for separate Wraith-specific carbon.

Installation & Reversibility

Bench time per side is typically 45–75 minutes for an experienced installer, slightly more if the original Mansory fender is being fitted at the same visit. The splitter locates on the OEM bosses inside the fender outtake, then keys onto the carrier bead before final torque on the concealed clips. No drilling, no cutting and no irreversible modification of OEM Dawn sheet metal is required: the carrier sits proud of the OEM aperture and shares its mounting points with the original blanking trim.

Surface prep matters more than fastening: the carrier surface must be cleaned with isopropyl, the adhesive bead applied at the right ambient temperature, and the assembly held under light pressure during the initial cure. A Rolls-Royce-certified body shop or a Mansory-trained installer is recommended for the first fitment to a freshly painted Mansory fender; thereafter, future removal and refitting is a clean reversible operation. DIY is feasible for an owner experienced with prestige-marque trim, but the deep-gloss lacquer is unforgiving and a bench mat is essential.

Pairing within the Mansory Dawn programme

The fender air-outtake splitter is rarely specified in isolation — it is the punctuation mark on the Mansory carbon front end. Pair it with the Mansory carbon front fenders as a matter of course; the splitter sits inside the fender's signature outtake aperture and the two parts are designed as a single visual gesture. Add the Mansory carbon mirror housings with indicator flasher to carry the lacquered weave back along the door line — it is the same horizontal carbon stripe in the side profile, only seen from above. For full front-to-rear coherence, mirror this fender detail at the back with the air-outtake splitter for the rear bumper: the result is a quiet symmetry — carbon vents bookending the car at each corner, without ever crossing into motorsport theatre.

Maintenance & Durability

Lacquered carbon on a drophead lives a harder life than on a coupé: more direct sun on the visible weave, more late-evening air dewing on the bonnet, more porte-cochère lighting cycling on a finish that is meant to look perfect under all of them. Wash with pH-neutral shampoo and a soft mitt only. Avoid alkaline traffic-film removers, ammonia-based glass cleaners drifting onto the panel, and any abrasive sponge — these are the three reliable killers of lacquered weave.

For long-term protection, a 9H-class ceramic coating applied over the Mansory lacquer is strongly recommended; it stabilises gloss against UV, makes the splitter easier to keep dust-free at the base of the fins, and extends the visual life of the deep-gloss layer. Carnauba wax is also kind to the lacquer but needs more frequent renewal. If a fin chips through impact, the splitter is removable as a unit and can be sent for refurbishment rather than replaced — a coachbuilt approach to a coachbuilt part.

Lead Time & Warranty

Production is bespoke. Lead time is typically 4–8 weeks from confirmed order, depending on weave choice, lacquer specification and any colour-keyed paint break specified for the carrier. Each piece carries a 12-month warranty against manufacturing defects in carbon and lacquer.

FAQ

Q: Will it fit a Rolls-Royce Dawn Black Badge?
A: Yes. The splitter is identical in fitment between Standard and Black Badge — both share the same front-fender outtake geometry. The finish on a Black Badge tends to be specified darker (shadow-chrome sympathies), but mechanically there is no difference.

Q: How much weight does it save versus the OEM blanking trim?
A: Honestly, very little — this is a styling and thermal-extraction part, not a weight programme. Net change per side is in the order of a few grams either way. Owners specify it for visual presence and for the small contribution to wheel-arch venting, not for kerb-weight figures.

Q: Can I have a satin or raw-weave finish instead of deep gloss?
A: Yes. Mansory will execute satin lacquer or fully raw exposed weave on request as a bespoke option. Most Dawn commissions stay with deep-gloss because it harmonises with the polished chrome surrounds and the Spirit of Ecstasy; raw weave is more often paired with murdered-out Black Badge specs.

Q: Does it interfere with soft-top stowage or the coach doors?
A: No. The splitter sits forward of the door cut and forward of the rear-deck stowage tonneau, so neither the fabric-roof mechanism nor the rear-hinged coach door comes anywhere near it during operation.

Q: Is the lacquered carbon stable in long open-top sun exposure?
A: Yes, when the lacquer is intact and the surface is maintained. Mansory uses two-pack UV-stable lacquer; layered with a modern ceramic coating, the splitter holds gloss across many seasons of drophead use. Direct sun is fine; abandoned grime is not.

Q: Will it fit a Rolls-Royce Wraith?
A: No. Despite shared underpinnings, the front-fender outtake geometry on Wraith differs and Mansory tools its splitters per car. A Wraith spec is a separate commission.

Pair it with the Mansory carbon fenders, the carbon mirror housings and a matching rear-bumper outtake splitter for a coherent coachbuilt front-to-rear carbon language. To commission this part as part of a wider Mansory Dawn programme, talk to us on WhatsApp +44 7488 818 747 or [email protected].
