Rear wing Mansory Carbon for Ferrari 812 Superfast Stallone

Rear Wing Mansory Carbon for Ferrari 812 Superfast Stallone

A rear wing on a naturally aspirated front-engine V12 GT is an engineering decision, not merely a styling statement. The Ferrari 812 Superfast develops 789 hp through the rear wheels alone, and at the speeds that horsepower enables — sustained runs above 250 km/h on unrestricted roads, corner-entry velocities above 200 km/h on a fast circuit — additional rear-axle traction from aerodynamic downforce is directly transformative. Mansory's carbon rear wing for the 812 Superfast Stallone delivers that load as an integrated element of the Mansory Body Kit for Ferrari 812 Superfast Stallone, shaped to complement the programme's widebody geometry and matched in 3K twill weave to the rest of the kit. The adjustable blade angle tailors the rear-to-front aero balance for road versus circuit priorities, and the filament-wound stanchions transmit full aerodynamic loads into the chassis without flex at speed.

Construction & Materials

The rear wing is cured in Mansory's autoclave at 125 °C and 3 bar from aerospace pre-preg carbon fibre. The full-width blade is a single-piece component with 3K twill skin at ±45° and unidirectional reinforcement along the span — the axis where aerodynamic downforce bending load concentrates. The ±45° skin resists torsional load from asymmetric airflow (crosswinds, yawed cornering) that would otherwise twist the blade and corrupt downforce consistency across the span. End plates are integrally moulded to the blade root flanges, eliminating the panel joint that becomes the first structural degradation point in bolt-together wing assemblies subjected to repeated thermal and aerodynamic cycling.

The hollow carbon stanchions are filament-wound rather than hand-laid, giving the circular cross-section uniform fibre distribution that maximises column buckling resistance under the compressive downforce load. Each stanchion accepts an M10 through-bolt into the OEM boot-lid reinforcement brackets. The complete assembly weighs approximately 2.6 kg — its contribution to the rear-axle sprung mass is negligible, while its aerodynamic contribution at speed is decidedly not.

Design & Visual Function

The blade geometry is calibrated for the 812 Superfast's operating speed range: 150–280 km/h, where the naturally aspirated V12 reaches peak output and where rear tyre loading is most critical. The cambered blade generates rear-axle load through suction on its lower surface, pressing the rear axle toward the road surface. At 200 km/h the wing delivers approximately 55–70 kg of rear-axle downforce — greater than the rear diffuser's contribution at the same speed — while adding less than 12 kg of aerodynamic drag. Chord and camber selection maximises the downforce-to-drag ratio at 200 km/h, ensuring aerodynamic gains are not offset by significant top-speed reduction at road-legal velocities.

Integral end plates prevent pressure equalisation around the blade tips that would reduce the suction differential generating downforce, and shed counter-rotating vortices that delay tip-stall and maintain consistent downforce across the full blade span. The ±5° adjustment range allows road versus circuit optimisation: neutral angle suits balanced use; maximum positive angle delivers peak rear-axle load for circuit traction. Adjustment takes five minutes per side with a 6 mm Allen key — no specialist equipment required, making track-day angle optimisation a practical paddock task.

From any viewing angle the rear wing anchors the Stallone's identity. From directly behind, the full-width blade frames the taillights and reinforces the wide-track silhouette. From the three-quarter rear, the stanchion rising from the boot lid creates the visual separation between body and sky that characterises GT racing prototypes. The matching weave texture integrates the wing into the programme's visual language rather than presenting it as a separately sourced afterthought.

Compatibility & Fitment

Fits the Ferrari 812 Superfast coupe on the F140 platform, 2017–2022. Mounts to the boot lid via OEM boot-lid reinforcement brackets at the trailing edge — provisions Ferrari over-engineered relative to production aerodynamic loads, providing adequate margin for the wing's downforce application. LHD and RHD both accommodated. Not compatible with the 812 GTS. Owners specifying both the rear wing and rear spoiler should select one, as both occupy the boot-lid trailing-edge position.

Installation & Reversibility

Wing installation is a 2–3 hour professional task that requires drilling through the boot-lid outer panel at Mansory template positions — the one step in the Stallone programme that permanently modifies a body panel. M10 through-bolts with interior backing plates prevent pull-through under maximum downforce loading. The blade mounts to the stanchion tops with its angle set by the cam-slot adjuster before locking. Mansory recommends a static wheel-alignment check after installation to verify the downforce loading's effect on rear suspension geometry is within tolerance. A Mansory-authorised bodyshop should perform all drilling and final torquing.

Pairing within the Mansory 812 Superfast Stallone Programme

The rear wing delivers the highest rear-axle load in the Stallone programme and should be complemented at the front axle for aero balance. The Mansory Splitter for Front Bumper adds front-axle load that prevents the forward-light sensation a purely rear-loaded car exhibits at high speed. Below the wing, the Mansory Rear Kit's diffuser supplements wing downforce at lower speeds where the wing's efficiency is reduced. The Mansory Rear Panel fills the quarter zone between the wing base, arch, and bumper with a continuous carbon surface.

Maintenance & Durability

The wing blade operates in clean air well above road surface level and accumulates less contamination than lower components. Wash with pH-neutral shampoo and microfibre; rinse at low pressure. Inspect stanchion-to-boot-lid joints for micro-cracks after each track session. Apply ceramic coating to the blade's lower suction surface annually. Verify the cam-slot locking bolt at each service — vibration can loosen it over time. Do not use alkaline cleaners or solvents near lacquered surfaces.

Lead Time & Warranty

Rear wing lead time is 5–7 weeks from confirmed order. The 12-month manufacturing warranty covers delamination and void formation. Boot-lid drilling, installation error, and impact damage are outside warranty scope.

FAQ

Q: How does the wing's downforce compare to the rear diffuser at the same speed?
A: At 200 km/h the wing generates approximately 55–70 kg of rear-axle load; the diffuser adds 35–45 kg simultaneously. Combined rear-axle aerodynamic load exceeds 100 kg at motorway speeds — substantially greater than the stock 812 Superfast's near-zero rear aero load at the same speed.

Q: Is boot-lid drilling permanent, and does it affect resale?
A: The drilling is permanent in the sense that it creates holes in the boot-lid panel. A professional bodyshop can plug, fill, and re-paint the holes to a standard matching the original finish, but this is a 4–6 hour repair requiring paint-code matching. Mansory recommends buyers confirm their intent to retain the wing before authorising the installation.

Q: Does the blade angle adjustment require removing the wing?
A: No. The cam-slot adjuster is accessible from the rear of each stanchion with a 6 mm Allen key; adjustment takes approximately five minutes per side. Loosen the locking bolt, rotate the cam to the desired position, and retighten to 12 Nm. Mansory recommends the neutral setting for road use and maximum positive angle for circuit work.

Q: Does the wing affect boot-lid opening or the rear-view camera angle?
A: Neither. Stanchions are positioned to clear the boot-lid hinge arc; the lid opens to its full design angle. The blade sits aft of the rear screen glass line and does not obstruct the rearview sightline from the driver's seat or the factory rear-view camera field of view.

Q: Can the rear wing be combined with the Mansory rear kit's diffuser for a full rear-aero specification?
A: Yes — and this is the recommended full rear-aero specification for circuit-focused builds. The wing generates high-speed downforce at the boot-lid level; the diffuser adds rear-axle load at lower speeds through underbody pressure recovery. The two mechanisms are independent and additive across the full speed range.
