Front fenders Mansory Carbon for Ferrari 812 Superfast Stallone

Front Fenders Mansory Carbon for Ferrari 812 Superfast Stallone

The widened front fenders are the defining structural element of the Mansory Stallone programme on the Ferrari 812 Superfast. Expanding the front track width by 40 mm per side, these carbon arches accommodate the Stallone's wider stance and wrap the 275/35 ZR20 front rubber in dramatically flared bodywork that signals the transformation immediately. As the signature width-defining piece within the Mansory Body Kit for Ferrari 812 Superfast Stallone, the fenders are where Mansory's autoclave expertise intersects with Ferrari's front-engine V12 GT proportions — producing an arch that reads aggressive in photographs yet flows naturally from the 812 Superfast's original design lines when seen in person. The naturally aspirated 6.5L V12 in the 812 Superfast generates heat concentrated within the engine bay rather than at the nose, so the fender architecture is optimised entirely for aerodynamic performance and brake-cooling efficiency without forced-induction thermal management competing for airflow priority.

Construction & Materials

The front fenders are the most geometrically complex carbon parts in the Stallone kit, requiring a five-section mould to capture the inward-rolled arch lip, the forward LED-lamp housing recess, and the three-dimensional surface transition into the door shut line. Autoclave cure at 135 °C produces the highest fibre volume fraction in the programme — important given the structural role of the fender in containing the wheel arch wash at speed and supporting the weight of the headlamp assembly. Each fender is post-cure trimmed by CNC routing to achieve the critical shut-line tolerances that Ferrari's own aluminium panels maintain at the door and bonnet edges.

• Weave: 3K twill on external face; 2K plain on arch inner liner
• Cure: autoclave at 135 °C / 7 bar, 120-minute dwell
• Wall thickness: 2.8–3.2 mm at arch lip, 2.2 mm on flat panels
• Weight per fender: approx. 2.1 kg (pair ~4.2 kg vs. OEM aluminium ~6.8 kg)
• Mounting: 8 × M8 OEM bolt positions plus 3M VHB tape along door shut flange
• Finish: high-gloss clear lacquer; satin or matte finish available
• Brake-cooling vent aperture pre-cut and dimensioned for Mansory air-splitter bracket
• CNC post-trim for door-gap tolerance ±0.5 mm

Design & Visual Function

At 40 mm wider than OEM, the Mansory front fender arch lip extends beyond the tyre contact patch profile, which is critical for roadworthiness across all regulatory jurisdictions — the arch must legally cover the tyre width in motion. The outward flare follows a tightly radiused knuckle that echoes Ferrari's racing lineage rather than the soft flowing arches seen on luxury GT competitors, giving the Stallone programme an unambiguous motorsport reference point alongside the aggressive rear wing and widebody rear quarters.

The forward section of the fender incorporates a ducted brake-cooling aperture — a 60 × 35 mm slot behind the leading arch lip that feeds ambient air toward the 398 mm front brake disc assembly. On the 6.5L naturally aspirated V12, brake thermal management is particularly important on track days because the F140 GA engine generates high cornering loads at its 8,500 rpm atmospheric operating range, placing corresponding demands on the Brembo caliper temperature during repeated braking events. This duct feeds cold air toward the disc face and reduces repeated-stop brake fade risk on the road circuit. The duct aperture is dimensioned to accept the separate Mansory air-splitter-for-front-fender component, which focuses the airflow more precisely toward the caliper inlet.

The LED headlamp surround geometry is preserved in the Mansory fender mould so the OEM Daytona-style quad-LED cluster reinstalls without modification to mounting brackets or electrical connectors. The weave on the visible fender surface is oriented at 45° consistent with the wider Stallone panel language, ensuring the chevron flash reads from headlamp to door handle without interruption when the car is stationary.

Compatibility & Fitment

For the Ferrari 812 Superfast coupé (F140-platform, naturally aspirated 6.5L V12, RWD, 2017–2022). The fender bolt pattern references the OEM aluminium mounting flange, unchanged across the 812 Superfast production run. The 812 GTS uses a different upper fender-to-windscreen pillar joint and is not compatible with this mould. LHD and RHD vehicles use the same fender geometry — the pair is supplied mirrored left and right. Wheel-arch clearance is confirmed for 275/35 ZR20 front tyres on standard-offset Ferrari wheels; aftermarket wheels with offset deviating more than ±5 mm require a clearance check before ordering. Cars fitted with the optional four-wheel steering (4WS) system are fully compatible — the 4WS actuator sits within the rear subframe and does not interact with the front fender geometry.

Installation & Reversibility

Replacing the front fenders is the most involved individual Stallone fitment. Removing the OEM aluminium fender requires draining the windscreen washer reservoir (routed under the fender liner on some build dates), removing the inner liner, disconnecting the OEM headlamp if built into the fender shell on pre-2019 builds, and extracting 8 M8 bolts. Allow 3–4 hours for a pair including refit of headlamps, liner, and sealing the door-shut flange with 3M VHB tape. A Mansory-authorised body shop is strongly recommended to maintain Ferrari factory warranty on adjacent paint and door seals.

Pairing within the Mansory 812 Superfast Stallone programme

Front fenders work most naturally with two complementary parts: the air splitter for front fender, which bolts to the fender's brake-cooling aperture and guides air toward the disc face; and the front-light air vents top, which vent the headlamp housing heat generated by the quad LED cluster. A full nose transformation adds the front kit to complete the visual and aerodynamic statement at the nose of the 812 Superfast.

Maintenance & Durability

Carbon fenders experience the highest stone-chip exposure of any Stallone panel — the arch lip directly faces road debris thrown by the 275/35 ZR20 tyre at speed. A paint-protection film (PPF) over the leading arch edge and the lower 80 mm of the fender face is strongly recommended at installation. Wash weekly with pH-neutral shampoo; avoid high-pressure lances aimed at the arch-to-body seam. Apply a ceramic coat to the clear lacquer every 6 months given the elevated debris exposure. Inspect the brake-duct aperture edges after each track day to ensure no stone has lodged and begun to abrade the carbon inner face. Lacquer life of 8–12 years is achievable with a PPF and ceramic coat maintenance regime. The inner arch liner — supplied in matching carbon — should be wiped annually with a silicone-free protectant to resist the salt spray and brake dust accumulation that can stain natural weave surfaces over time.

Lead Time & Warranty

The front fender pair has a lead time of 3–5 weeks given the multi-part mould and autoclave scheduling. Covered by Mansory's 12-month warranty against delamination, mould voids, and structural failure under normal road use. Track-day kerb and debris impacts are excluded from the manufacturing warranty.

FAQ

Q: Do I need to re-spray surrounding panels to match after fitting carbon fenders?
A: Carbon-finish fenders are delivered lacquered to a high-gloss sheen that requires no paint match — they are intended to contrast with the body colour. If you order a colour-matched (paint-over-weave) variant, adjacent panels may need blending to achieve a perfect factory-quality door-gap colour match.

Q: Are the brake-duct apertures functional or merely cosmetic?
A: The apertures are structurally open and dimensioned to feed the Brembo front caliper area. Ducting functionality is maximised when paired with the dedicated Mansory air splitter for front fender, which channels the airflow precisely against the disc face rather than allowing it to disperse within the arch.

Q: Is the headlamp mounting compatible with adaptive headlamps (OEM optional)?
A: Yes — the Mansory mould preserves all six OEM headlamp mounting points including the adaptive motor bracket position used on cars with the optional AFS headlamp system specified from factory.

Q: What is the weight saving over OEM aluminium fenders?
A: Approximately 1.3 kg per fender (2.6 kg per pair), a meaningful saving given the front-engine weight distribution of the 812 Superfast, where reducing unsprung and nose weight directly improves steering response.

Q: Can these fenders be fitted to a 812 Stallone V2 or Competizione?
A: No — this mould is specific to the standard 812 Superfast. The Stallone V2 and Competizione have different OEM arch geometry and require separate tooling to achieve correct panel gaps and arch clearances.
