Roof spoiler II Mansory Carbon for Audi RS Q8

Roof Spoiler II Mansory Carbon for Audi RS Q8

Roof Spoiler II is the bigger statement in the Mansory roof aero family for the Audi RS Q8 (4M chassis), the flagship 600 hp twin-turbo V8 mild-hybrid coupe-SUV that already arrives wearing a substantial OEM lip at the trailing edge of the roof. Where Type I keeps things subtle, Type II goes taller and deeper — a more aggressive leading edge, a longer chord, a more pronounced underside cavity. It belongs to the wider Mansory Carbon Fiber Body kit set for Audi RS Q8 and is the part owners specify when they want the silhouette to read clearly Mansory from twenty paces, not just from a rear-three-quarter walk-around.

Construction & Materials

Type II is a meaningfully larger laminate than Type I, and the build reflects that. Mansory autoclaves the part at full pressure and temperature, then trims and finishes by hand before the lacquer step. The result is a stable shell that holds its line at autobahn velocity without buzz or flex, even with the deeper underside scoop opening the lower face to slipstream loads.

• Autoclave-cured prepreg carbon, 3K twill weave on the visible upper and trailing-edge surfaces.
• Wall thickness 2.0–2.6 mm across the visible skin, locally thicker at the leading-edge knuckle.
• Component weight 1.6–1.9 kg depending on finish (lacquer adds mass over raw).
• Mounting: 3M VHB structural adhesive tape pre-applied along the roof-skin contact face.
• Internal aluminium reinforcement bonded along the underside chord to keep camber straight.
• Finish options: gloss lacquered carbon, matte lacquered carbon, or solid body-colour paint to OEM Audi codes.
• Edges sealed against UV ingress; underside primed to prevent moisture migration through the laminate.

Design & Visual Function

Type II is fundamentally a chord-and-height story. The leading edge sits taller off the painted roof skin than Type I, the chord is longer fore-to-aft, and the trailing lip drops further down. From the side that gives the RS Q8 a more obvious break between the painted roof and the carbon volume, especially in two-tone matte-roof specifications. From the rear, you read a deeper carbon strip across the upper rear-glass margin instead of a thin pinstripe — it’s the difference between “Mansory” and “definitely Mansory”.

Aerodynamically, the larger physical signature does real work. The taller leading-edge step lifts the roof streamline a few millimetres earlier, and the longer chord gives the airflow more distance to attach cleanly along the upper surface before separating off the trailing lip. That keeps the wake structure further from the rear glass, helps the rear-decklid surface see less turbulent flow, and produces a measurable downforce contribution at motorway-plus speeds — useful on a 2,315 kg coupe-SUV that runs to 305 km/h with the Dynamic+ pack. The deeper underside cavity is the other half of that story: by hollowing more volume out of the lower face, the part behaves like a small low-pressure pocket that pulls airflow up off the rear glass, mitigating the dirty-water-and-dust film that collects at high speed on the RS Q8’s steep rear glass.

Visually it integrates with the rest of the roof line by mirroring the curvature of the rear quarter-glass DLO. The third brake light surround is reshaped rather than blanked — the LED window stays exactly where Audi put it, certified, with no DRL or third-light loss. Paint-match opens the door for owners running mono-tone Performance specifications who want the deeper presence without the carbon contrast; specify an Audi paint code at order and Mansory will finish to that.

Compatibility & Fitment

Audi RS Q8 (4M chassis), MY2020+ — both pre-facelift 2020–2023 and facelift Performance 2024+. Mansory tools the bond face to the OEM roof skin profile, which the facelift did not change, so a single Type II part covers both. Third-light cut-out is reshaped to the Type II surround geometry; the OEM LED unit transfers across without rework. ACC radar, washers, parking sensors, headlight aim and any drive-mode actuators in the bumper are unaffected — Type II lives entirely on the roof.

Installation & Reversibility

Type II is a 3M VHB-bonded part. The car is parked indoors at 20–24°C with the air-suspension lifted to give roof-edge access from a platform; OEM roof skin is degreased with isopropanol and lightly primed; the third-light unit is removed and refitted into the new surround once the spoiler is in place. Bond pressure is held with masking tape for the cure window. From start to drive-out is around three to four hours including cure. Reversibility is in principle yes, but Type II is a larger, heavier part than Type I — removal heats the bond and pulls the laminate cleanly, but lacquer touch-up to the underlying roof is recommended afterwards. We strongly advise installation at a certified body shop, not DIY.

Pairing within the Mansory RS Q8 programme

Within the genuine Mansory carbon line, Type II pairs as follows. If you want the more restrained roof signature instead, look at the Roof spoiler I — same family, smaller chord and lower leading edge, a quieter visual that suits owners who already run other carbon volumes elsewhere on the car. The two are mutually exclusive on a given car: pick the one that matches your overall aero language. Once Type II is on, balance it with the Roof spoiler extension, the small carbon blade that adds further drag-balance and trailing-edge presence at the very rear of the roof line. And to keep the rear elevation coherent with the deeper roof signature, specify the Rear decklid spoiler II — the larger of the two trunk-edge spoilers, which echoes Type II’s scale across the rear deck and keeps the upper and lower aero volumes in proportion.

Maintenance & Durability

Lacquered carbon is straightforward to keep alive provided you respect what kills it. UV is the slow killer; ceramic coating after install pays for itself across a decade of summer sun. Carnauba waxes look fine but offer almost no UV protection, so on a daily-driven RS Q8 a proper SiO2-based ceramic is the right answer. Avoid ammonia-based glass cleaners on or near the carbon edges; they soften lacquer and lift the seal. Avoid alkaline wheel cleaners drifting onto the rear roof during a wash. If a stone strike chips through to weave, repair is a body-shop job — strip the lacquer locally, fill the chip with epoxy, reweave-blend if necessary, recoat. Done early, repairs are invisible. Done late, after moisture has migrated under the lacquer, the affected zone usually has to be rebuilt.

Lead Time & Warranty

Lead time 4–7 weeks from order, with the part going through Mansory’s standard autoclave-cure-trim-finish workflow. Paint-matched specifications add roughly a week for code matching and bake. Each piece is photographed pre-shipment so you can sign off the weave alignment and lacquer flatness before dispatch. 12-month warranty against manufacturing defects covering laminate delamination, lacquer crazing not caused by impact, and bond-tape adhesion failure under normal use; impact damage and chemical etching from incorrect cleaning chemistry are excluded.

FAQ

Q: How is Type II different from Type I in practice?
A: Bigger physical part. Taller leading edge, deeper chord, more pronounced underside cavity. The aero contribution is meaningfully greater and the visual statement is much stronger. Type I is the subtle option; Type II is the assertive option.

Q: Does Type II fit both pre-facelift and the 2024+ Performance?
A: Yes. The roof skin geometry did not change with the facelift, so one part fits both production windows.

Q: Will I lose the third brake light?
A: No. Type II reshapes the surround so the OEM LED third-light unit is retained in its certified position. Nothing about the lighting approval changes.

Q: Can I order Type II in body colour rather than visible carbon?
A: Yes. Specify your Audi paint code at order; Mansory finishes to that code in their paint shop. Lead time extends by about a week.

Q: Is the bond strong enough at autobahn speed?
A: Yes. The 3M VHB pre-applied tape, with the aluminium reinforcement chord on the underside, is engineered for sustained 250 km/h+ loads. The deeper Type II underside cavity does not compromise the bond — load is carried at the contact face along the roof skin.

Q: Can I run Type I and Type II together?
A: No. They occupy the same area on the roof and are alternatives. The roof spoiler extension is the part that complements Type II at the rearmost roof edge.

Type II is the part you choose when you want the RS Q8 silhouette to read aggressive Mansory at a glance. Pair it with the roof spoiler extension and Rear decklid spoiler II for a coherent statement across the upper rear of the car.
