Rear spoiler Mansory Carbon for Lamborghini Aventador S

Mansory Carbon Rear Spoiler for Lamborghini Aventador S

The Mansory carbon rear spoiler sits at the gentlest end of the Aventador S aerodynamic ladder. Where pedestal-mounted wings declare themselves from a hundred metres away, this piece slips quietly across the trailing edge of the engine bonnet — a low-profile ducktail lip that reads, at a glance, as if Sant'Agata had bolted it on at the factory. It belongs to the wider Mansory Body Kit for Lamborghini Aventador S programme, sharing the same 3K twill, the same autoclave cure schedule and the same lacquer system as the bumpers, side skirts and diffuser. Behind it the naturally aspirated 6.5-litre V12 still breathes through its high-mounted intakes; below it the lower-side exhaust outlets stay untouched. This is the choice for owners who want measured downforce, an undisturbed roof-line and a road-friendly silhouette — not a track-day banner.

Construction & Materials

The spoiler is laid as a single moulded shell with an internal stiffening rib that runs the full width. Mansory uses prepreg 3K twill on both faces — a tighter, more disciplined weave than the 12K patterns favoured by aftermarket suppliers — and cures the part in an autoclave so that the lacquered surface holds its gloss without the orange-peel that vacuum-only cures sometimes produce. Edges are CNC-trimmed; the underside is left in a satin tooling finish so that thermal expansion at the engine-bay seam does not telegraph through.

• Weave: 3K twill, prepreg, ±0.4 mm pattern alignment across the centreline
• Cure: autoclave, 7 bar, programmed ramp peaking at 125 °C
• Wall thickness: 1.6–2.0 mm shell, 3.0 mm at the integrated rib
• Mass: ~1.4 kg painted, ~1.2 kg raw weave (replaces a body-coloured OEM trailing-edge panel where fitted)
• Mounting: factory bonnet trailing-edge bolt pattern reused; supplementary 3M VHB 5952 strip for the seam
• Finish: lacquered 2K clear, satin or gloss; raw matte available as a no-cost option
• UV pack: HALS-stabilised topcoat with measured Δb after 1,500 h QUV
• Hardware: marine-grade A4 stainless studs, nylon washers to protect the bonded substrate

Design & Visual Function

Visually the part adds about 35–45 mm of vertical lip at the trailing edge and tapers to nothing at the corners. Read against the Aventador S engine bonnet, it picks up the same crease that runs from the rear quarter glass and lets it die into the bodywork rather than continuing into a wing element. The lacquered 3K weave catches light differently than the surrounding paint — at idle it looks like a calm, uniform crosshatch; under sun and movement it animates and gives the rear three-quarter view a layered, three-dimensional quality.

Aerodynamically the brief is modest. The lip nudges the rear stagnation point upward, raises the local pressure on the bonnet's top surface and reduces the lift coefficient by a measured but unspectacular margin — useful at autobahn speeds and motorway cruise, not transformative on a circuit. Because the Aventador S has no central active-aero channel above the engine, Mansory was free to span the full width without leaving a gap. The result is closer in feel to an OEM ducktail than to an aftermarket wing.

The piece also re-frames the rear glass. With the spoiler in place the engine bay reads as a single architectural plane that ends in a defined edge — much like a 911 GT3 Touring's lip versus a 911 GT3's swan-neck. For owners who specified a Roadster the visual logic is the same; the lip terminates clear of the targa panel stowage cut-line.

Compatibility & Fitment

Designed for the Lamborghini Aventador S (LP740-4 S), coupé and Roadster, model years 2017 through 2021. The spoiler respects the pre-SVJ rear bumper geometry and the lower-side exhaust outlet positions; it does not interfere with rear parking sensors, the camera housing or the centre brake-light reflector. OEM scissor-door hinge geometry, oil-cooler intake plumbing and the bonnet release mechanism remain stock. On Roadster cars the targa panel still seats and stows without any reach over the lip.

Installation & Reversibility

Bench time runs about 90 minutes for an experienced installer; allow half a day if the owner specifies body-colour respray of an OEM panel for archival storage. Tools: T20/T25 Torx, an 8 mm socket, panel-removal wedges, isopropyl wipe-down kit, low-tack masking tape, a torque wrench rated to 12 Nm and an adhesion promoter compatible with methacrylate-bonded substrates. The Aventador's CFRP monocoque uses methacrylate adhesive bonds at certain panel interfaces, so the recommended primer is one that explicitly lists MMA compatibility on its data sheet — a generic acrylic promoter can soften the bond line.

Reversibility is straightforward. The factory studs are reused, the VHB seam strip lifts cleanly with heat from a 600 W gun and a fishing-line cutter, and the underlying paint is undisturbed if the prep was done correctly. We recommend a Lamborghini-authorised body shop or a Mansory-trained installer for the first fit; subsequent removal for transport or seasonal storage can be handled by any competent detailer.

Pairing within the Mansory Aventador S programme

This spoiler is the subtlest of four rear-element options Mansory offers for the Aventador S. The other three are progressively more assertive: the rear performance wing introduces a single-tier pedestal-mounted blade for owners who want a clear visual statement and meaningful downforce at speed; the biplane performance wing stacks two elements for a layered look and higher Cl with controlled drag; and the rear high-performance wing is the largest of the catalogue, intended for owners chasing maximum rear-axle load on circuit days. Owners typically choose this ducktail when the rest of the build is restrained — body-colour bumpers, factory-look diffuser, satin wheels — and when the car will spend most of its life on road rather than track.

Maintenance & Durability

Lacquered 3K weave is durable but chemistry-sensitive. The two enemies are alkaline cleaners (degreasers, traffic-film removers above pH 10) and ammonia-based glass sprays drifting onto the lacquer during a quick wipe-down — both will haze the topcoat over months rather than days. Use pH-neutral shampoo, a soft microfibre and straight-line wash technique. A ceramic coat of 9H or higher gives roughly two years of UV and chemical buffer; a carnauba paste is acceptable for show cars but needs reapplication every six to eight weeks.

The Aventador's V12 hot zone produces serious thermal load through the engine deck. The spoiler sits forward of the worst of it but still benefits from a thin reflective foil applied to the underside in the seam area; this slows the lacquer's natural ageing curve under repeated heat-soak cycles. Stone-chip repair on a lacquered weave is a multi-step process — fill, sand, blend, re-lacquer — and is best handled by a paint shop with carbon experience.

Lead Time & Warranty

Lead time is typically 4 to 8 weeks from order confirmation. Mansory builds in measured production runs rather than continuous batches, so cards are sequenced around weave-stock availability and autoclave slot. Each part carries a 12-month manufacturing-defect warranty covering delamination, lacquer failure unrelated to misuse and dimensional non-conformance. UV fade after the warranty period falls under the standard maintenance regimen.

FAQ

Q: How much downforce does this actually add?
A: Modest. Lift coefficient at the rear axle drops by a measured but small margin — useful at sustained motorway speed and meaningful in feel above 200 km/h, not transformative on a circuit. The pedestal wings in the catalogue are the answer if circuit performance is the goal.

Q: How does this compare visually to the OEM Lamborghini ducktail accessory?
A: Similar silhouette, different surface language. The OEM piece is body-coloured GFRP; the Mansory part is lacquered 3K twill carbon, slightly taller at the centreline and noticeably more architectural under directional light.

Q: Will it fit my Aventador S Roadster?
A: Yes. The targa panel stowage path is clear of the lip, and the seal line at the rear glass is unaffected. Fitment is identical between coupé and Roadster.

Q: Raw weave or lacquered — what should I order?
A: Lacquered 2K clear is the default and the more durable choice. Raw matte gives a darker, more muted look but is less forgiving of fingerprints, polish residue and roadside dust. We supply both; about three quarters of cards leave with the lacquered finish.

Q: Can I run this spoiler with the rear performance wing for a layered look?
A: Mansory does not recommend stacking the two — the lip's purpose is to be the rear element on its own. If a layered visual is the goal, the biplane performance wing is the correct option in the catalogue.

Q: Does it interfere with the rear-view camera or parking sensors?
A: No. The lip sits on the bonnet trailing edge, well forward of the camera and sensor housings on the rear bumper. Reverse imaging and parking aids continue to operate as factory.

Pair this spoiler with a body-coloured rear bumper, a satin-finish diffuser and the standard Mansory side skirts for the most coherent restrained build, or step up to one of the pedestal wings if circuit-day downforce is on the brief.
