Rear bumper air outtake cover II Mansory Carbon for Lamborghini Aventador Competition

Mansory Carbon Rear Bumper Air Outtake Cover II for Lamborghini Aventador Competition

The Rear Bumper Air Outtake Cover II is the heavier, louder sibling within the Mansory Carbon Body Kit for Lamborghini Aventador Competition programme. Where the I version sits flush and aerodynamic, the II adopts a markedly broader perimeter, a deeper louvre stack and a more sculptural visual mass — engineered to frame the Aventador's rear bumper side outlets with motorsport-leaning theatre. On a 6.5-litre naturally aspirated V12 chassis where the SVJ ALA channel reigns and the central twin-exhaust dominates the centreline, this II cover hands the lateral bumper zone an unmistakable racing identity, fully respectful of scissor-door geometry and the aluminium-CFRP monocoque substrate behind it.

Construction & Materials

Each cover is laminated as a single bonded shell using prepreg carbon fibre and cured under autoclave heat-and-pressure cycling. The result is a dimensionally locked panel with a louvre array deep enough to read from twenty metres yet light enough to leave OEM bumper crash hardware untouched. Mansory's atelier finishes the weave with UV-stable aerospace clearcoat, sealing colour depth and protecting the lacquered surface from underbody grit and wheel-arch fling.

• Prepreg laminate, predominantly 3K twill, oriented to align with louvre flow lines
• Autoclave cure for void-free density and tight tolerance retention
• Wall thickness ranging 1.9-2.4 mm depending on louvre rib height
• Component mass roughly 0.55-0.7 kg per side — louvre depth adds vs the I cover
• Stainless retainer clips with neoprene-bonded gasket against the OEM bumper face
• Lacquered glossy weave standard; raw matte and silk-satin available bespoke
• Optional forged-marble carbon for visual contrast against the lacquered louvres
• UV-stable aerospace clearcoat sealing the entire visible surface

Design & Visual Function

The II cover's defining trait is louvre count. Where the I variant runs a tighter, shallower set of slats, the II expands both the rib height and the rib pitch — giving the rear bumper flank a perforated, almost endurance-prototype look. Deeper louvres throw stronger shadow lines under low sun, which lengthens the visual mass of the rear quarter and visually pulls the wheel arch outward. Around the perimeter, an enlarged carbon frame extends the cover's footprint over more of the bumper sculpting, hiding more of the painted surface and presenting a more uninterrupted carbon plane.

Thermally, the deeper louvre stack opens additional escape area behind the rear wheel arch — a useful trait given the V12's prodigious rear thermal load and the heat-soak that gathers around the central twin-exhaust on SVJ. Air leaving the wheel-arch volume passes through the louvre slats with reduced backpressure compared to the slimmer I cover, helping rear-tyre temperature stability during sustained on-limit driving. Naturally, the cover does not interfere with the V12's airbox feed nor any oil-cooler routing — it manages spent rear-arch flow only.

Visually, the II reads as motorsport. Its proportions echo Mansory's Carbonado and J.S.1 design language but lean further into endurance-racing iconography: pronounced rib shadows, thicker frame, more pronounced fender shoulder. Owners who want their Aventador Competition to look as if it has just stepped off a paddock truck specify the II; those who prefer subtle aerodynamic continuity choose the I.

Compatibility & Fitment

Engineered for Lamborghini Aventador LP700-4, LP750-4 SV, S, SVJ and Ultimae — coupé and Roadster body styles alike. The cover seats over the OEM rear bumper side outtake aperture and uses the factory mounting reference points already present on the painted bumper. Pre-SVJ bumper geometry is slightly narrower than SVJ-spec; both are accommodated through the lacquered cover's tolerance band, but Mansory advises confirming chassis VIN at order so the production team can match curvature exactly. ALA 2.0's central rear-wing channel sits well inboard of this part, so SVJ aero behaviour is unaffected. The high-mount central twin-exhaust on SVJ remains fully visible, while the lower side outlets on LP/S also remain unobstructed. Parking sensors integrated in the rear bumper continue to read normally — the cover does not encroach on their detection cone.

Installation & Reversibility

Fitting the II cover is a focused workshop task lasting 45-75 minutes per side. The OEM bumper need not be removed; technicians clean the bumper face with isopropyl, dry-fit the cover to verify alignment with the bumper character lines, then bond using a structural acrylic adhesive system that is friendly to the methacrylate chemistry already used on Aventador body bonds. Stainless retainer clips engage the cover's inner perimeter to OEM ribbing, mechanically backstopping the adhesive bed. A secondary primer is applied around louvre rib feet to lock against vibration micro-creep over years of road use. Reversibility is straightforward: the cover lifts off cleanly with controlled heat, and any residual adhesive is mechanically scraped and chemically wiped without damaging factory paint. We recommend a Mansory-trained installer or a Lamborghini-certified body shop, especially because the II's broader perimeter demands tighter alignment with the bumper's painted shoulders than the I cover requires.

Pairing within the Mansory Aventador Competition programme

The II cover is most often specified alongside its mirror sibling — the original Rear Bumper Air Outtake Cover I — when an owner wants a clear visual differentiator between left and right flanks for show-build photography, or when collectors stock both to swap based on event setting. More commonly, the II is paired downstream with the matching Rear Bumper shell so the entire rear face reads as a single coordinated carbon volume, and underneath with the Designed Diffuser to extend the louvre theme into the rear-floor strake structure. Should a customer want the I treatment instead for one side or for a second car in the collection, the Rear Bumper Air Outtake Cover remains in catalogue.

Maintenance & Durability

Lacquered weave responds best to pH-neutral shampoo, soft microfibre and a two-bucket wash. Avoid alkaline traffic-film removers, ammonia glass cleaners, and anything abrasive enough to micro-scratch the clearcoat. A ceramic coating (six- to nine-H grade) extends gloss life significantly versus carnauba and is recommended for daily-driven Aventadors that see weather. The deeper louvre rib geometry of the II cover collects more dust and tyre rubber than the I — a soft-bristle detail brush clears the rib roots in a few minutes, and a steam pass restores the deep shadow line. Stone-chip exposure is moderate; the II's taller ribs can occasionally take a chip on rib leading edges, which Mansory's chip-repair workflow handles by feathering, infill resin and local clearcoat blend in a half-day visit. Engine-bay heat from the V12 hot zone reaches the cover only indirectly — wheel-arch transfer rather than direct radiation — so thermal degradation is not a practical concern within the part's expected lifespan of well over a decade.

Lead Time & Warranty

Bespoke production, queued through the Mansory atelier, runs 4-8 weeks from order confirmation. Each cover is hand-finished, clearcoat-cured and inspected by metrology jig before despatch. A 12-month manufacturer warranty applies against laminate defects, delamination and clearcoat micro-cracking under normal use; the warranty excludes impact damage, chemical attack from non-recommended cleaners, and modifications to the part by third parties.

FAQ

Q: How does the II differ from the I cover in practice?
A: The II runs a deeper louvre stack with taller ribs and a broader carbon perimeter. The I is flusher, slimmer, and closer to OEM proportion. The II reads racing, the I reads sport-luxury.

Q: Will the II cover work with my pre-SVJ Aventador bumper?
A: Yes — both pre-SVJ and SVJ bumper geometries are catered for. Confirm VIN at order so curvature is matched exactly during production.

Q: Does the louvre depth interfere with the SVJ's ALA system?
A: Not at all. ALA 2.0 routes through the centre rear wing; the side outtake covers operate on the lateral wheel-arch flow only.

Q: Can I order one II cover and one I cover for a custom asymmetric build?
A: Yes, asymmetric pairing is supported as a bespoke order. Lead time matches the slowest of the two pieces.

Q: How much weight does the II cover add or save versus OEM?
A: Marginal — net change is within ±0.4 kg per side. The visual and thermal benefits drive the specification rather than mass reduction.

Q: Raw matte or lacquered for a track-leaning Aventador?
A: Raw matte tightens the motorsport read and resists rib-edge chip glare. Lacquered keeps gloss continuity with painted bodywork. Both are stocked.
