Rear spoiler Mansory Carbon for Lamborghini Aventador Competition

Mansory Carbon Rear Spoiler for Lamborghini Aventador Competition

Some owners want the V12 to do its talking and the silhouette to stay roughly factory. The Mansory carbon rear spoiler answers that brief inside the Mansory Carbon Body Kit for Lamborghini Aventador Competition programme. Rather than a freestanding aerofoil on milled risers, this piece is a sculpted ducktail lip integrated to the engine-bonnet trailing edge — a kicked extension of the existing bodywork that quietly shifts the rear pressure field. It sits over the naturally aspirated 6.5-litre V12, between the scissor-door cuts and ahead of the high-mount twin-exhaust on SVJ-trim chassis, and it leaves the central ALA 2.0 channel exactly where Sant'Agata put it. For owners chasing a road-friendly stance with a wink at OEM ducktails of the past, this is the most considered option in the wing line.

Construction & Materials

The spoiler is laid up as a single-piece carbon shell with internal ribbing — the trailing-edge cross-section is hollow but stiffened by a moulded box near the centreline so it does not pant at speed. Mansory uses a prepreg-then-autoclave cycle for the visible skin and a closed-cell core only where the section gets thick; the result is a panel that bonds to the bonnet's trailing edge as if it had always been there. There is no pedestal hardware to clean, no torque sequence on uprights, no risk of the part walking under load.

• 3K twill outer ply, ~0.25 mm — the weave runs longitudinally so it draws the eye toward the diffuser, not across.
• Inner structural plies: 2x2 twill at 45 degrees plus a unidirectional spine along the kick-up.
• Cure: autoclave prepreg, ~120 deg C, 6 bar dwell — uniform glass on the lacquer.
• Wall thickness: 1.6–1.9 mm at the leaf, 3.2 mm at the bonded foot.
• Mass: ~0.9 kg installed (roughly a third of the lightest pedestal wing in the catalogue).
• Bonding: structural methacrylate plus a row of M5 captive nuts inside the bonnet skin for a mechanical safety.
• Finish: clear UV-stable 2K lacquer (gloss / satin) or raw weathered weave with PPF for purists.
• Tolerance to the bonnet shutline: ±0.4 mm cosmetic gap, sealed with low-modulus joint sealant.

Design & Visual Function

Where a pedestal wing announces itself, this spoiler whispers. Profile in side view is a soft kick — five to seven degrees of upturn over roughly 180 mm of chord — that follows the natural curvature of the engine bonnet and breaks the airflow leaving the rear glass slightly later than stock. In aero terms the part works the lift coefficient: at moderate road speeds, where a freestanding wing's drag tax outweighs its downforce gift, an integrated lip nudges the rear axle's lift coefficient measurably negative without piling on frontal area. You will not match the rear-axle bite of the largest performance wing on a circuit, but on a fast B-road the car feels planted to the rear without the autobahn drone of a tall element catching crosswinds.

Visually, the spoiler reads as if Sant'Agata had drawn it. It honours the OEM Aventador ducktail vocabulary — the same family as the small lip on early LP700 and the sharper kick on the SV — and gives it the J.S.1 finish: deeper weave, crisper end caps, a chiselled outboard taper that aligns with the bodyline running off the rear haunch. There is no fight with the SVJ central exhaust outlet because the part terminates a clean 70 mm forward of the exit; thermal soak from the V12 hot zone never touches the lacquer.

Critically, the part does not interrupt the ALA 2.0 channel on SVJ chassis. ALA's central duct exits behind the engine cover via the rear wing's pylon stalk and stalls the wing for low drag on demand; this spoiler lives entirely on the engine-bonnet plane and never crosses the ALA path. Owners running ALA in track mode see no parameter shift on the active-aero diagnostics — the system continues to vector flow to the wing exactly as it did from factory.

Compatibility & Fitment

Fits Lamborghini Aventador LP700-4, LP750-4 SV, S, SVJ, Ultimae — coupe and Roadster. The bonded foot is moulded against the OEM bonnet trailing edge geometry that is shared across the LP/SVJ generations, so pre-SVJ and SVJ chassis use the same physical part; the difference is only in the bonnet variant beneath (engine-bonnet for coupe, engine-bonnet-cabrio for the Roadster soft-top mating). The spoiler clears the Roadster's targa-style top-stowage operation: with the panels stowed in the front trunk and the soft tonneau closed, the trailing edge of the spoiler sits well clear of the upper deck cinematics. OEM rear visibility is preserved because the kick is below the rear glass eyeline.

Installation & Reversibility

Installation is the simplest of any rear-aero option in the kit — Mansory installers budget 90 to 150 minutes for a clean fit. The bonnet trailing edge is degreased and abraded to a defined key, the structural methacrylate is applied in a metered bead, the M5 captive locator pins drop into pre-drilled positions, and the part is clamped while the adhesive snaps. Painted finishes: prep, base, clear, polish — usual three-day cycle if colour-matched. The Aventador's CFRP monocoque uses methacrylate adhesive bonds throughout, so the chemistry is consistent with the original build language; a Lamborghini-certified body shop or a Mansory-trained installer is recommended for the bonded interface, though the part is reversible — it can be cut off and the bonnet trailing edge restored or replaced with a new OEM panel without monocoque intervention.

Pairing within the Mansory Aventador Competition programme

The Aventador Competition catalogue offers four answers to the same question — how loud should the back of your car be? Listed quietest to loudest:

• This integrated ducktail spoiler — modest lift-coefficient effect, road-friendly, OEM-adjacent silhouette.
• Rear performance wing — pedestal-mounted single-tier element, the everyday track answer.
• Biplane performance wing — twin-tier stack for owners who want the J.S.1-style visual punch and flat-top downforce.
• Rear high-performance wing — the largest element, made for circuit duty and overt aero theatre.

If your Aventador Competition build is grand-tourer biased, this spoiler is the right call. If it is going to see Nardo or a club track day, step up to one of the pedestal-mounted siblings.

Maintenance & Durability

Lacquered carbon hates two things: ammonia-laced glass cleaners and abrasive sponges. Wash with pH-neutral shampoo and a microfibre noodle mitt; protect with a ceramic coat (Si02 9H or better) for daily-driven cars or a hard carnauba layer for show cars. UV is the long-term enemy of any lacquer — park in shade where you can and refresh the ceramic every 18 months. Because the spoiler sits over the engine bay, it lives close to the V12's thermal field; the autoclave cure handles the heat and the trailing-edge geometry pulls hot air off the bonnet rather than pooling it, but a thin reflective heat shield on the underside of the lip keeps the lacquer cool during summer traffic crawls. Stone chips on the leading kick are repairable — a Mansory-trained refinisher can sand-blend, re-clear and polish without leaving a witness line.

Lead Time & Warranty

Lead time runs four to eight weeks from order, in line with Mansory's bespoke production cadence — the spoiler is laid up to order and the chosen finish (gloss, satin, or raw weave with PPF) is applied before despatch. Warranty is 12 months against manufacturing and adhesion defects from the date of fitment.

FAQ

Q: Is this part visible at all from inside the cabin?
A: No. The kick sits below the rear-glass eyeline; rearview-mirror geometry is unchanged.

Q: Does it interfere with ALA 2.0 on the SVJ?
A: No. The spoiler lives entirely on the engine-bonnet plane and never crosses the ALA central channel or the wing-pylon stalk. ALA continues to stall and re-load the rear wing on demand.

Q: How much downforce does it actually add?
A: At moderate motorway speeds the part nudges the rear lift coefficient measurably negative without the drag penalty of a pedestal wing. It is a stability and feel upgrade for road use, not a circuit aero solution — choose one of the pedestal wings if you want measured kg of rear downforce.

Q: Will it fit a pre-SVJ LP700-4 cleanly?
A: Yes. The bonded foot is moulded against the bonnet trailing-edge profile shared across LP/S/SV/SVJ/Ultimae, coupe and Roadster.

Q: Can I run this and later switch to a pedestal wing?
A: Yes. The spoiler is reversible — the methacrylate bond can be cut, the bonnet trailing edge refinished or replaced, and a pedestal-mounted wing installed in its place.

Q: Raw weave or lacquered — which holds up better?
A: Lacquered survives UV better long-term; raw weave looks more aggressive but needs PPF for any car that lives outdoors. Both are offered.
