Mansory Body Kit for Ferrari 812 Superfast Stallone

MANSORY Stallone for the Ferrari 812 Superfast — the last front-engine naturally-aspirated V12 Ferrari

The 812 Superfast occupies a specific place in Ferrari's lineage: it is the final production Ferrari to combine a front-engine layout, a mid-rear-transmission V12, and natural aspiration. Its 6.5-litre F140 GA V12 produces 800 PS at 8500 rpm without a turbocharger or an e-motor in the loop, and it is the direct successor to the F12 Berlinetta. Ferrari has replaced it with the 12 Cilindri for the 2025 model year. The Mansory Stallone carbon programme on this page is the workshop's flagship V12 build on that end-of-line donor, and this page walks through the Stallone kit's widebody geometry, why the donor's naturally-aspirated V12 is the reason the exhaust SKU sells at near-100% attach rate, and where end-of-line 812 collectors are specifying the programme in 2026.

An end-of-line V12 donor and what that means for the order book

The 812 Superfast went out of Ferrari production with the 812 Competizione and the Competizione A as its final halo variants. The 12 Cilindri now carries the front-engine V12 berlinetta badge forward, but the 12 Cilindri is not the 812 — it is a new chassis on a new platform, and the 812 donor pool is now finite. The Mansory order book in 2026 therefore reads more like a collector-market census than a volume distribution: where the surviving 812 Superfast donors sit is where the Stallone kit ships. This is a different ordering pattern from Mansory Ferraris still in production (the 296 GTB, the SF90, the Roma), where the workshop builds against the dealer's new-car pipeline.

The Stallone kit — widebody carbon for the V12 body

Stallone is the Mansory workshop's published name for the full 812 programme. Unlike the narrow-body kits the workshop publishes for most Ferraris, the Stallone programme is a genuine widebody conversion: the front and rear carbon fender flares add approximately 30 mm of track per side, and the programme's bumpers, skirts and diffuser are dimensioned to the flared arch geometry rather than the OEM 812 arch line.

Parts list:

• Front: widebody carbon fender flares (L&R), front bumper with enlarged cooling intakes feeding the V12 radiator stack, front lip / splitter with flow vanes, vented carbon bonnet with twin louvre outlets sized to the V12 under-bonnet heat signature, carbon grille frame.
• Sides: widebody side skirts (sized to the flared rocker line), carbon mirror caps, carbon door-handle trim overlays.
• Rear: widebody carbon rear fender flares (L&R), rear apron with integrated diffuser dimensioned to the flared rear arch, fixed carbon rear wing with adjustable angle, Stallone-branded rear reflector surrounds.
• Exhaust (near-mandatory on this donor): stainless Mansory Stallone sport exhaust with quad-tip trim. See below on attach rate.

Materials: dry carbon on the bonnet, wing, ducktail and fender flares (all visible carbon weave), PU-RIM composite with carbon trim on the bumpers (optional full-dry-carbon upgrade on both front and rear bumper), 2x2 twill visible weave as the surface finish.

Why the exhaust SKU attaches at near-100% on this donor

The 812 Superfast's 6.5 V12 is the last naturally-aspirated V12 Ferrari produces. The donor is commissioned by buyers specifically for that engine character — the 8900 rpm redline, the naturally-aspirated throttle response curve, and the V12 exhaust note are the buying proposition. The factory Ferrari exhaust on the 812 Superfast is a competent quad-tip stainless system, but Mansory's Stallone sport exhaust opens the valve mapping at lower rpm and lets the V12 voice through at mid-range engine speeds where the factory system remains partially muted. Owners who specify the Stallone bodywork almost universally add the exhaust — our internal order-book analysis places the exhaust attach rate above 95% on this specific donor, a much higher rate than on any other Mansory Ferrari programme.

Engine — the NA V12 stays factory unless you are routed to the engine cell

The Stallone bodywork and exhaust together do not change the F140 GA V12's 800 PS rating. Mansory's per-VIN engine-cell commissions for the 812 donor include intake, camshaft timing and exhaust header work that can lift peak power into the 850–880 PS range; this is a specialist engineering commission and is handled outside the catalogue. The 812 Competizione engine at 830 PS factory is a separate powertrain calibration from Ferrari and the Stallone kit fits the 812 Competizione body physically — see FAQ.

Wheels — 21" front / 22" rear staggered forged

The OEM 812 Superfast ships on 20" forged factory wheels with 275-section front and 315-section rear tyres. Mansory's Stallone wheel is a staggered 21" front / 22" rear forged multi-spoke in a colour-coded or raw-finish specification. The staggered geometry suits the widebody flared arch proportions; a non-staggered 21"/21" option is available for track-day commissions. Owners who keep the OEM 20" forged for track use and specify the 21"/22" staggered Stallone wheel for road use are a recurring pattern. Wheel range at Hodoor forged wheels.

A factory-allocation order book — where the 812 went when it was new

The 812 Superfast's geography in 2026 is largely a reflection of where Ferrari originally allocated the donor when it was new between 2017 and 2022. Ferrari's factory allocation to markets drove the surviving donor pool, and the Mansory commission now follows that allocation decades later.

The single largest geography is the United States, concentrated in three corridors: South Florida (Miami / Palm Beach / Naples), the Northeast luxury corridor (New York tri-state / Greenwich / Boston), and Southern California (Beverly Hills / Newport Beach). Ferrari's US allocation to the 812 Superfast was generous and the donor concentration today sits deep in established Ferrari collector households. The US does not have a country-blog page — 812 Stallone commissions ship through the same dealer service routing as other Mansory Ferrari orders.

Italy and Monaco form the second-largest cluster. Monaco absorbed a disproportionate share of European 812 allocation (Ferrari's home-region allocation bias favours Monaco and the Côte d'Azur), and the surviving garage-kept 812 population in Monaco is the densest per-square-kilometre 812 cluster in the world. Italian owners — concentrated in Milan, Rome and Florence — commission the Stallone programme at a high rate for the Superfast because the car's final-V12 status is a collector framing that Italian Ferraristi respond to.

The Gulf Ferrari allocation in 2017-2022 skewed toward the 812 Superfast (Gulf buyers preferred the V12 GT proposition over the mid-engine F8). The UAE, Saudi Arabia, and Qatar together carry the third-largest Stallone order book. Gulf commissions trend toward full dry-carbon bumpers and toward Stallone's more visible carbon-weave specification.

The UK and Switzerland carry a smaller but recurring share — UK 812 Stallone buyers skew toward body-colour bumpers and understated weave specifications, and the Swiss cluster concentrates on summer-garage second cars. Japan takes a disciplined collector share concentrated in Tokyo.

Sister Mansory Ferrari V12 and the 812 Stallone GTS variant

The 812 Superfast Stallone is one of three Mansory 812-platform lines: this page for the Superfast Coupé, the 812 Stallone GTS page for the Spider / GTS body variant, and the Competizione (per-VIN commission, not a catalogue page). The closest NA-V12 sibling in the Mansory Ferrari catalogue is the F12berlinetta La Revoluzione — Ferrari's previous-generation front-engine V12 and the 812's direct predecessor. Collectors frequently commission both cars to matching Mansory weave specifications.

Ordering & lead time

Full Stallone widebody carbon set: five to seven weeks from the workshop (longer than narrow-body kits because of the fender-flare bonding window). Stallone sport exhaust: three weeks. 21"/22" staggered forged wheel set: four to five weeks. Email [email protected] or WhatsApp +44 7488 818747 with your VIN, the body variant (Superfast Coupé — this page — or GTS Spider, which routes to the separate 812 Stallone GTS page), the OEM Ferrari paint code, weave specification, and preferred delivery. Note that fender-flare bonding makes the kit non-trivial to remove for resale — commissions are typically long-term ownership decisions rather than short-turnaround builds.

FAQ

Does the Stallone kit fit the 812 Competizione or the Competizione A?
The bodywork dimensioning is shared between the 812 Superfast and the 812 Competizione — the Competizione is a high-engineering-spec variant of the same body. The Mansory Stallone kit fits the Competizione physically. However, the Competizione's factory specification is already near-saturation on weight reduction and aerodynamic engineering, and Competizione owners commissioning Mansory work are typically routed to per-VIN custom rather than the catalogue Stallone kit.

Does the kit fit the 812 GTS Spider?
No — the GTS has a different rear-deck geometry to accommodate the retractable hardtop. 812 GTS owners route to the separate 812 Stallone GTS Mansory page.

Is the fender-flare bonding reversible for resale?
Partially. The flares are epoxy-bonded to the OEM fender edge; the bond is removable by a coachbuilder but leaves a bonding residue line on the OEM fender. Collector resale inside the Ferrari channel typically requires OEM fender replacement to return the donor to stock appearance. Resale inside the Mansory-collector channel trades at a modest premium on verified Stallone provenance.

How does the Stallone exhaust compare to the factory AMG-style Ferrari exhaust character?
The 812's factory exhaust is a valve-operated quad-tip system with Ferrari-calibrated mapping. The Stallone system opens the valve window earlier in the rpm range (from roughly 3500 rpm in the Mansory mapping vs roughly 4500 rpm factory) and lets the V12's throat characteristic through at mid-range engine speeds. The exhaust does not change peak horsepower but it meaningfully changes daily driving character.

Will the Mansory front bumper clear the 812's factory front-lift hydraulic system?
Yes. The Mansory front bumper preserves the factory front-lift system's actuator geometry and the lift-height range. Most Stallone commissions specify the front lift as a mandatory option on donors that do not already have it.

Does the fixed carbon rear wing replace the 812 Superfast's factory active-aero tabs?
The 812's rear aerodynamics are passive on the base Superfast — the small active-aero flap elements on the rear quarters are preserved by the Mansory rear apron and the fixed carbon wing adds downforce without removing the factory flaps. On the Competizione variant the factory aerodynamic package includes a fixed rear wing already, and the Mansory fixed wing replaces it.
