Race flaps for front bumper Mansory for Ferrari 812 Superfast Stallone

Race Flaps for Front Bumper Mansory Carbon for Ferrari 812 Superfast Stallone

Circuit driving exposes the outer lower corners of the Ferrari 812 Superfast's front fascia to a specific category of hazard that road use rarely produces: the repeated close-clearance pass over raised circuit kerbs, the chicane apex that brings the front corner within millimetres of a painted concrete edge, the hairpin entry where the car's natural line passes across the ripple-strip. Mansory's carbon race flaps for the front bumper address this directly — a pair of shaped carbon panels that sit at the outer lower corners of the front bumper and bear the first contact in any near-miss with a kerb or circuit debris, protecting the bumper, the splitter, and the full front kit structure from the sustained cosmetic and structural damage that high-frequency kerb exposure causes. They are part of the Mansory Body Kit for Ferrari 812 Superfast Stallone specifically for owners who use the 812 Superfast as intended: at the limit of its naturally aspirated V12's 8500 rpm capability, on circuits where speed and placement margin are measured in centimetres.

Construction & Materials

The race flaps are fabricated from pre-preg carbon fibre autoclave-cured at 125 °C and 3 bar — the same manufacturing process used throughout the Stallone programme — but with a layup schedule specifically tuned for controlled-impact resilience rather than maximum stiffness. The structural core uses a balanced woven carbon at 45° to the primary impact direction: this orientation allows the laminate to absorb an oblique strike's energy through matrix micro-cracking — a benign, contained failure mode — rather than through catastrophic fibre fracture that could send fragments toward the tyre sidewall. The outer visible face retains the 3K twill aesthetic of the Stallone programme, maintaining the visual consistency of the lower front-corner treatment when viewed from circuit photography angles.

The mounting flanges are designed for direct attachment to the bumper's lower outer corners using the existing M6 captive nut positions, with an additional rearward bracket that ties the flap to the wheel-arch liner inner surface for torsional stiffness. This dual-point attachment means the race flap transfers any kerb-impact load to the bumper structure's outer corners — the stiffest zone in the front fascia assembly — rather than to the bumper's central intake face, which is the most expensive piece to repair. The flaps weigh approximately 0.38 kg each (0.76 kg for the pair), a negligible addition to the front-axle unsprung and sprung mass.

Design & Visual Function

The race flap's form is governed primarily by its protective function, but Mansory's designers have incorporated an aerodynamic secondary benefit in the process. The flap's inboard face is shaped to continue the outer air curtain duct geometry of the bumper, redirecting flow that exits the lateral duct downward and outward in a direction that prevents it from re-entering the wheel well as separated turbulence. This controlled exhaust of the lateral duct's air reduces the drag penalty that an abrupt termination geometry would impose and maintains the air curtain's thermal-isolation function through a wider speed range. The net effect is a component that adds circuit protection without the aerodynamic cost that bluff or geometrically naive corner guards typically incur.

The flap's outer profile aligns precisely with the outer bumper corner's arc when installed, creating a visual continuation of the bumper's outer edge rather than an obviously added appendage. From the track-side viewing angle — low, from the outside of a corner — the race flap reads as an integral part of the front corner's carbon geometry, not a protective afterthought. The leading lower edge of each flap carries a 6 mm-radius reinforced carbon bead that is the designated contact surface in a kerb strike: hard enough to survive glancing contact without permanent deformation, shaped to deflect rather than hook on raised kerb profiles.

At speed, the race flaps add a small amount of additional front-corner visual mass, reinforcing the Stallone's wide-stance appearance from the front three-quarter view. The additional carbon geometry at the outer lower corners of the bumper gives the programme's front end a more complete look — the corners no longer end abruptly at the bumper outer edge but continue as a purposeful flange extending downward and rearward, echoing the functional architecture of single-seater and GT3 race car front aerodynamic packages.

Compatibility & Fitment

The race flaps for the front bumper fit both the Mansory carbon front bumper and the standard OEM Ferrari 812 Superfast bumper, covering all model years from 2017 to 2022. LHD and RHD variants are accommodated — the pair includes both a left-hand and right-hand flap. The race flaps are compatible with the Mansory front splitter installed simultaneously; the two components occupy adjacent but non-overlapping attachment zones on the bumper's lower face. The flaps are also compatible with the 812 GTS front bumper, an exception to the standard cross-compatibility rules, because their attachment points fall in an area of the front corner that did not change between the coupe and GTS variants.

Installation & Reversibility

Race flap installation takes approximately 25–35 minutes per flap. Each flap ships with its full M6 fastener set and the pre-fitted rearward arch-liner bracket. Offer the flap to the bumper's outer lower corner with the car at ride height on a level surface to confirm the geometric alignment before tightening — the flap should sit flush with the bumper outer edge and parallel to the ground at its lower bead. Tighten the bumper captive-nut bolts to 5 Nm and the arch-liner bracket bolt to 4 Nm. No adhesive or tape is required. The installation is fully reversible without damage to the bumper; the flaps can be removed and refitted at any track-day service interval in under five minutes with a single Allen key. It is common practice to remove race flaps for road use and refit them at the circuit, though their road appearance is considered desirable by most Stallone owners.

Pairing within the Mansory 812 Superfast Stallone Programme

Race flaps and the front splitter are the natural pairing for any owner who uses the 812 Superfast on circuit, as they address the two most common sources of lower-front-corner damage in different ways: the Mansory Splitter for Front Bumper generates downforce at the front axle and the race flaps protect the outer corners from the kerb contacts that the splitter's projecting geometry makes more likely. At the transition from the front corner to the sill, the Race Flaps for Front Bumper Lip provide complementary protection at the lower lip zone, covering the geometry below the main bumper face that is exposed during close-contact cornering. For the brake-duct circuit directly above the race flap attachment line, the Air Splitter for Front Fender optimises the ducted airflow to the front brakes, completing the front-corner's thermal management architecture for sustained track use.

Maintenance & Durability

Race flaps accumulate road grit and tyre spray residue on their inboard faces after track use; rinse these surfaces with clean water at low pressure after each circuit session and dry with a microfibre cloth before inspection. Inspect the leading edge bead after every track day for deformation or surface cracking — a small crack in the 6 mm leading edge bead can be stabilised with thin cyanoacrylate before it propagates. The outer 3K twill face is susceptible to fine abrasion from tyre spray; a single layer of clear PPF on the outer face before the first track event extends the lacquer's service life significantly. Unlike the main bumper panels, race flaps are considered replacement items rather than repair items — if one sustains a direct strike that causes structural fracture beyond the designed micro-cracking zone, replace it rather than attempting a structural repair, as the impact-absorption geometry of the layup may be compromised. Mansory supplies replacement flaps individually and keeps them in production throughout the 812 Superfast Stallone programme's lifecycle.

Lead Time & Warranty

Race flap pairs ship within 2–3 weeks of confirmed order — one of the faster lead times in the Stallone programme, reflecting the relatively simple autoclave geometry compared to the front kit or wing components. The 12-month manufacturing warranty covers delamination and void formation. Impact damage and wear from normal track and road use is expected operational consumption rather than a manufacturing defect.

FAQ

Q: Do the race flaps fit the OEM Ferrari 812 Superfast bumper as well as the Mansory carbon bumper?
A: Yes — both the OEM and Mansory bumper variants are supported.

Q: Are these flaps suitable for road use, or only for circuit sessions?
A: The race flaps are designed for circuit use but function entirely normally on public roads. Many Stallone owners leave them fitted permanently — the added visual mass at the outer lower corners of the bumper is considered part of the Stallone aesthetic.

Q: How do these race flaps differ from the race flaps for the front bumper lip?
A: The race flaps for the front bumper mount at the bumper's outer lower corners — protecting the bumper face geometry and the splitter end plates. The race flaps for the front bumper lip mount at the lower lip edge — the extreme lowest forward extent of the front fascia, closer to the road surface.

Q: Can the race flaps be installed without removing any body panels or lifting the car?
A: Yes. The race flap attachment points are accessible from below the car at normal ride height with a standard inspection lamp and a short-handled Allen key. No body panel removal or vehicle lifting is required. This accessibility makes track-day refitting from the boot of a support vehicle a realistic option between sessions.

Q: What is the lead time if I need the flaps for a specific race event?
A: Standard lead time is 2–3 weeks. If you have a confirmed race date, contact us as early as possible via WhatsApp +44 7488 818 747 so we can allocate a production slot timed to your event. Rush production can sometimes be accommodated for single-item orders like these flaps — the key variable is the current autoclave schedule at Mansory.
