Rear bumper air outtake cover Mansory Carbon for Lamborghini Aventador

Rear Bumper Air Outtake Cover Mansory Carbon for Lamborghini Aventador

Behind the Lamborghini Aventador's rear bumper, two distinct thermal and aerodynamic processes converge: hot air exiting the V12 engine bay needs a directed extraction path, and the rear aerodynamic platform needs lateral flow management to prevent the turbulent wake behind the rear tyres from undermining downforce generated by the diffuser below. The Mansory rear bumper air outtake cover — a component of the Mansory Carbon Fiber Body kit set for Lamborghini Aventador — occupies the lateral aperture of the rear bumper, replacing the factory painted-plastic or mesh filler with a precision-louvred carbon face that manages both processes simultaneously. It is a small part by surface area but a significant one by aerodynamic and visual contribution.

Construction & Materials

The outtake cover presents one of the more challenging small-part geometries in the Mansory Aventador programme: the louvre blade cluster must be precisely registered within a housing aperture whose inner face is curved in two planes to match the Aventador's rear bumper geometry. Mansory achieves this with a matched positive/negative tooling system that forms the housing and blade cluster as a single co-cured assembly — eliminating the mechanical joints between blade and housing that can loosen under the high-amplitude vibration of a naturally aspirated V12 at full-song revs.

• Housing and blade weave: 3K twill on visible outer surfaces; 2K plain on housing inner bracket faces
• Cure: Autoclave, co-cured assembly — blade roots fully integrated, no adhesive joints
• Blade wall thickness: 1.0 mm — minimal obstruction to outtake airflow cross-section
• Housing wall thickness: 2.0 mm — rigid enough to maintain aperture geometry under heat soak
• Operating temperature tolerance: the toughened epoxy system retains full stiffness to 130 °C — well above the rear bumper ambient temperature in sustained high-speed driving
• Finish: high-gloss UV-clear lacquer on visible blade faces and housing surround
• Mounting: snap-fit into OEM bumper aperture; stainless-steel retention pins supplied
• Weight: approximately 0.35 kg per unit

The operating temperature specification deserves emphasis: the rear bumper zone of the Aventador is one of the hottest exterior surfaces on the car in sustained driving. The V12 exhaust manifolds, sitting just forward of the rear bumper inner face, radiate continuously; the rear diffuser further concentrates underbody heat at the trailing edge. Mansory specifies a toughened epoxy system with a continuous-service rating of 130 °C precisely to maintain structural integrity in this environment — standard aerospace-grade epoxies can soften above 90–100 °C, causing blade sag in the highest-temperature service cycles.

Design & Visual Function

The rear bumper lateral apertures are among the most scrutinised details on the Aventador at static shows — every viewer examining the rear of the car sees them at eye level. Replacing the factory treatment with Mansory's louvred carbon cover transforms these apertures from a passive filler into an active design statement: the parallel blade lines create a rhythm that echoes the diffuser's channel geometry below and the body kit's lateral accent lines above, unifying the rear end under a single graphic logic.

Aerodynamically, the louvre blade angle — set at 18 ° from vertical — directs outtake airflow rearward and slightly outward, away from the diffuser's inlet zone. This prevents the hot engine-bay exhaust air from re-entering the diffuser's underbody suction field, which would reduce the diffuser's effective pressure differential. The interaction between rear bumper outtake and underbody diffuser is a known sensitivity in mid-engine supercar aero tuning: getting it right requires that the outtake is positioned and angled to complement the diffuser rather than compete with it. Mansory's Aventador programme coordinates these two elements as an integrated rear aero package.

From a visual standpoint, the cover's high-gloss lacquer reflects the car's body colour in the blade faces, creating a layered visual effect — visible carbon weave on the structural face, painted colour reflected in the blade surfaces — that changes character depending on ambient lighting and the car's own colour specification.

Compatibility & Fitment

Designed for the Lamborghini Aventador LP 700-4 (2011–2016) and LP 720-4 50° Anniversario. The rear bumper aperture geometry is shared between coupé and Roadster. A second variant — the rear bumper air outtake cover II — provides an alternative blade pattern and visual treatment for owners who want a different aesthetic emphasis within the same aperture. Aventador S (MY2017+) uses a redesigned rear bumper; the Mansory S programme covers those covers. Both LHD and RHD cars use identical rear bumper geometry.

Installation & Reversibility

The snap-fit design makes this one of the quickest installations in the programme. With the car at a comfortable working height, removing the factory bumper filler and seating the Mansory cover into the aperture takes 20–30 minutes per side — no tools beyond a plastic trim tool and the supplied retention pin punch. The snap-fit system engages with a tactile click; final security comes from the retention pins. Full reversibility is preserved — the factory fillers reinstall identically. This is an appropriate first Mansory upgrade for owners who want to assess fit quality and visual impact before committing to larger body panel changes.

Pairing within the Mansory Aventador programme

The rear bumper air outtake covers form the natural companion set with the designed diffuser below and the rear bumper air outtake cover II — which provides the alternative blade geometry for owners building a full rear-bumper carbon wrap. Add the rear performance wing to complete the rear aero package: wing above, outtake covers mid-bumper, diffuser below — the three elements together create the Aventador's most dramatic and functionally coherent rear profile.

Maintenance & Durability

The louvre blades accumulate tar spray from the rear tyres at a higher rate than any other Mansory component due to their position directly behind the rear wheel arch exit. A dedicated rear-bumper tar remover (citrus-oil-based, not caustic alkaline) applied monthly dissolves tyre rubber deposits from the blade faces without attacking the urethane clear coat. Inspect the retention pin engagement quarterly — the vibration environment at the rear of a naturally aspirated V12 is severe, and pin migration over time can cause the cover to develop a slight rattle before becoming loose. Reseat and re-pin at the first sign of movement.

Lead Time & Warranty

The rear bumper air outtake cover is a precision small-part item. Lead time is 2–3 weeks from order confirmation. Mansory covers the part with a 12-month warranty against manufacturing defects including blade delamination at the root, retention-pin socket failure under normal thermal cycling, and lacquer voids visible at normal inspection distance. Tar-and-rubber contamination of the blade faces is a maintenance item, not a warranty matter.

FAQ

Q: Is the outtake cover supplied for one side or as a pair?
A: As a matched pair — the left and right covers are laid up in the same weave batch to ensure matched texture and gloss across both apertures when viewed simultaneously from the rear.

Q: What is the difference between this cover and the "II" variant?
A: The standard cover uses a parallel horizontal blade pattern with 18 ° blade angle. The II variant uses a diverging blade geometry — blades splay outward from the centre — for a more aggressive visual emphasis and slightly greater outflow spread angle. Both provide equivalent thermal and aerodynamic performance; the choice is aesthetic.

Q: Can the cover tolerate the heat from an aftermarket exhaust system?
A: The toughened epoxy system retains structural integrity to 130 °C — above the rear bumper ambient in normal V12 operation. Aftermarket exhaust systems with routing that directs hot gas directly toward the bumper inner face should be assessed case-by-case; radiant temperatures above 130 °C at the bumper inner face are unusual but possible with some race-spec systems.

Q: Does the outtake cover require any sealant at the aperture edge?
A: No sealant is required for the standard snap-fit installation. A light bead of body-compatible silicone at the housing perimeter is optional on cars used in sustained rain — it prevents water ingress through the aperture edge gap, which is otherwise inconsequential in dry climates.
