Performance wing for GTC Mansory Carbon for Bentey Continental GT
Mansory Carbon Performance Wing for Bentley Continental GTC (3W Convertible, 2003–2011)
The Bentley Continental GTC presents a fundamentally different engineering problem for a rear wing than the coupé. The GT coupé carries a rigid steel C-pillar and a solid boot lid structure — both load-bearing surfaces for wing leg attachment. The GTC eliminates the C-pillar entirely; the B-pillar transitions directly to rear quarter panels, and the boot lid zone is partly displaced by the soft-top mechanism housing. Mounting a performance wing here demands a purpose-designed approach. Mansory's carbon fibre performance wing for the GTC spreads wing loads across the rear quarter panels and a reinforced boot lid bracket, with leg geometry designed around the tonneau zone — a distinct engineering solution, not a repurposed coupé part. This component is part of the Mansory Carbon Fiber Body Kit Set for Bentley Continental GT, where each part is engineered to the specific chassis variant it serves.
Construction & Materials
The GTC performance wing uses a single aerofoil element — not the biplane configuration of the coupé wing. The GTC's tonneau zone and soft-top mechanism housing limit available height above the rear deck; a biplane with the required 55 mm inter-element gap would exceed available headroom or interfere with the roof travel path. Mansory uses a high-camber single-element profile sized to generate comparable rear-axle downforce within the convertible's packaging envelope. Wing element: 3K twill prepreg over a UD spar tape and foam core, autoclave-cured at 120 °C. Endplates: 3K twill prepreg, 6 mm wall, GTC-specific base geometry distributing load across the rear quarter panel and boot lid bracket. Leg structure: UD carbon tube, GTC-specific footprint at the base.
The high-camber profile generates downforce comparable to the coupé biplane despite the single element. Span approximately 1,050 mm, chord 220 mm. Complete assembly weight approximately 2.9 kg. Attack angle adjustable ±4° from neutral — same system as the coupé wing. Clear lacquer over 3K twill is standard; satin and gloss lacquer available.

Design & Visual Function
The GTC has an aerodynamically distinct rear compared to the coupé. The soft-top housing creates a blunt rear deck that generates a large separated wake at speed — a low-pressure zone reducing rear-axle traction. A wing here is particularly effective because it interrupts this separated wake, replacing the low-pressure separation with an organised downforce-generating flow regime. At 100 km/h the high-camber single element generates approximately 40–55 kg of rear-axle downforce — comparable to the coupé biplane — because the GTC's more turbulent rear deck wake provides additional aerodynamic headroom for the wing to act against. At 160 km/h, approximately 60–80 kg. The adjustable attack angle allows maximum rear downforce for circuit use, or reduced drag for extended road driving.
The visual transformation on the GTC is significant. The open-top body, absent the fastback roofline of the coupé, can read as formally understated from the rear-three-quarter angle. The performance wing changes this: the single-element carbon aerofoil elevated above the rear deck creates a strong silhouette change visible from directly behind and from the rear-three-quarter angle. Against any body colour the carbon endplates and aerofoil read purposefully. The wing's span coordinates visually with the tonneau cover and rear spoiler in the same zone, creating a consistent carbon graphic at the rear.
Compatibility & Fitment
GTC convertible only — 3W chassis, 2003–2011. NOT compatible with the GT coupé, which uses the biplane performance wing or biplane wing with decklid spoiler. NOT compatible with 2nd-generation GTC (D2A chassis, from 2011). Compatible with all 1st-gen GTC variants: W12 6.0L twin-turbo (all specifications) and 4.0L V8 twin-turbo (late facelift). Rear body geometry and mounting zones are identical across engine variants. Mounting requires drilling of rear quarter panels and boot lid bracket at GTC-specific positions. LHD and RHD geometry is symmetric at the wing mounting zone.
Installation & Reversibility
Installation time is 4–6 hours — longer than the coupé wing because the GTC mounting involves both rear quarter panels and boot lid zones, and leg positions must clear the soft-top mechanism travel path. Mansory supplies a drilling template calibrated to the GTC body. Wing legs bolt through the rear quarter panels into reinforcing backing plates supplied in the kit. After installation, a full soft-top open-close cycle must be completed with the wing fitted before delivery to the owner — the entire mechanism travel is checked for any contact with the wing structure. If contact is found, mounting positions must be reviewed against the Mansory template before the car leaves the workshop. Reversibility: the drill holes are not factory apertures and are not reversible without panel repair. Professional installation by a body shop experienced with the GTC and the Mansory template system is strongly recommended.
Pairing within the Mansory GT 3W Programme
The GTC performance wing pairs directly with the rear spoiler for GTC at the boot lid lip and the carbon cover of folding roof in the tonneau zone — these three together form the complete GTC rear carbon programme. The wing's rear-axle downforce pairs with the rear bumper with Diffuser I for combined upper and lower rear aerodynamic treatment. These four components form the complete GTC rear aero specification. The GTC rear suite integrates with the shared-body components: front bumper with front lip, side skirts, front fenders with stripe, mirror housings, and bonnet options — Engine Bonnet I and Engine Bonnet II.
Maintenance & Durability
The GTC wing faces full weather and aerodynamic loading plus an additional factor: when the soft-top is operated in wet conditions, moisture and roof fabric particles can accumulate between the wing underside and rear deck. Inspect the wing underside and leg bases annually for debris or moisture; clean with a dry cloth or gentle compressed air. Do not use solvents near the leg insert seals. If the carbon tonneau cover is fitted, check periodically that the gap between leg bases and the cover edge is clear. Wash carbon surfaces with pH-neutral shampoo; inspect lacquer annually for chips or crazing. Ceramic coating on wing faces is recommended for cars in outdoor storage or high-UV conditions.
Lead Time & Warranty
Standard lead time is 4–6 weeks for the complete assembly in clear lacquer. The GTC performance wing is produced on separate tooling from the coupé wing — GTC body style and model year must be confirmed at order. Satin or gloss lacquer adds approximately one week. 12-month warranty from delivery against manufacturing defects: delamination, structural laminate voids, endplate-to-leg fitment failure, and lacquer defects. Damage from incorrect installation — drill positioning outside the Mansory template zone — is not covered; the drilling template is supplied precisely to prevent positioning errors.
FAQ
Q: Why is the GTC wing a single element rather than biplane like the coupé wing?
A: The GTC's tonneau zone and soft-top housing limit available height above the rear deck. A biplane with the required 55 mm inter-element gap would require an assembly height that exceeds available headroom without interference with the roof mechanism during travel. The high-camber single-element profile delivers comparable rear-axle downforce to the coupé biplane within the convertible body's packaging constraints.
Q: Does the wing interfere with the GTC's soft-top operation?
A: The leg geometry is designed around the soft-top mechanism's travel path. Post-installation, the mandatory check is a full open-close soft-top cycle with the wing fitted, observing the mechanism at all points for contact. Provided the wing is installed at the exact Mansory-specified positions using the supplied drilling template, there is no interference. Incorrect mounting positions from inaccurate drilling are the primary risk — professional installation with the Mansory template is mandatory, not optional.
Q: Does the performance wing affect the OEM wind deflector?
A: The GTC's wind deflector rises from behind the rear seats within the cockpit — an interior component. The Mansory rear wing is on the exterior rear deck. They are entirely independent: the deflector deploys inside the cabin; the Mansory wing is on the outer deck surface. Both can operate simultaneously without mechanical interaction.
Q: Can I specify the GTC wing in satin finish to match a matte body wrap?
A: Yes — satin matte lacquer is a standard finish option. The same UV-stable two-component lacquer is applied in a low-sheen formulation over the 3K twill prepreg. On matte-wrapped or satin-finish cars, satin carbon creates a cohesive low-gloss appearance. Specify at order; satin finish adds approximately one week to lead time.
Q: Is the GTC performance wing compatible with the late V8 twin-turbo GTC?
A: Yes. The 4.0L V8 twin-turbo GTC shares the same rear body structure as the W12 GTC — rear deck geometry and mounting zones are identical. The wing fits both without modification. Engine variant only needs to be specified if also ordering a rear bumper diffuser, to ensure correct exhaust aperture dimensions on that component.
