Mansory Carbon Add-on Parts for Front Bumper, HIGH Side Flaps — Mercedes-AMG GT (C190)

This is the HIGH side flaps variant of the Mansory carbon add-on parts for the front bumper of the Mercedes-AMG GT (C190) — the front-mid-engine super-GT powered by the 4.0-litre M178 V8 BiTurbo with its hot-V turbo architecture and rear-mounted DCT transaxle. Within the wider Mansory Carbon Fiber Body kit set for Mercedes-Benz AMG GT S Coupe, this set sits as the visual-width-led member of a three-way add-on family: a base no-flaps version, a LOW-flaps version that hugs the road for ride-height drama, and this HIGH-flaps version that lifts the flap line upward to broaden the car's stance across the eyeline of the front bumper.

Construction & Materials

The HIGH side flaps are produced from autoclave-cured prepreg carbon laminate, weave-aligned across both flaps so that the twill pattern reads as a mirrored pair when seen straight-on. Each flap is a thin, sculpted blade tied into a mounting plate that bonds to the OEM front bumper sides; the geometry rises into the wing-arch transition rather than dropping to the air. This is what defines the HIGH variant — the flap chord runs above the front-lip line, taking visual cues from GT3-derived fender exits rather than from low canard splitters.

• Weave: 3K twill, deep-gloss lacquered (raw exposed weave with UV clear available on request)
• Laminate: prepreg, autoclave cured under pressure for void-free skin
• Wall thickness: ~2.0–2.4 mm at the flap blade, ~3.0 mm at the mounting plate
• Pair weight: ~1.1 kg total for the two flaps
• Hardware: 3M VHB structural tape pre-applied + four M5 stainless threaded studs per side
• UV inhibitor: cycloaliphatic clearcoat over the lacquer for long-term yellowing resistance
• Edge finish: machined and hand-flattened, no exposed cut fibres
• Fitment templates: paper masking templates supplied for stud-hole drilling

Design & Visual Function

Where the LOW-flap variant pulls the eye downward and emphasises ride-height-low theatre, the HIGH-flap variant does the opposite: it draws a horizontal line across the upper third of the front bumper and pulls the visual width outward. On a C190 with the long-bonnet / cab-rearward proportions, that high horizontal line works against the natural verticality of the Panamericana grille (post-2017 facelift) and balances the wide rear haunches over the DCT transaxle. The car looks broader from the front three-quarter, without losing any front-bumper air to the M178's intercoolers.

Aerodynamically the flaps are a mild add — a small vertical fence either side of the front bumper that helps to clean the wake at the front wheel and suggests, rather than enforces, downforce. Owners who track the car will pair these with a more committed front-lip and a wing-led rear; owners using the GT or GT S as a road super-GT use the HIGH flaps for the visual upside without paying the daily-driver tax that low canards demand.

The flaps also harmonise with the wide-body-kit fenders. Because the chord sits high, the flaps line up with the wide-body fender flare line rather than diving below it — visually the front bumper, fender, and door now read as one continuous wide line rather than as stacked elements. Combined with mirror covers in matching weave and the Panamericana grille mask, the whole front of the car presents as a single GT3-flavoured carbon mass.

Compatibility & Fitment

Designed for the Mercedes-AMG GT (C190): GT, GT S, GT C, GT R, GT R Pro and Black Series — Coupé and (with installer confirmation) Roadster. NOT compatible with the 4-door AMG GT 63 (X290) — the X290 is a separate platform with its own bumper architecture. The HIGH flaps fit both pre-facelift (Diamond grille) and post-2017 facelift (Panamericana) cars because they bond to the bumper sides rather than to grille architecture, but owners pairing this part with the Mansory grille mask should remember the grille mask itself is Panamericana-only. AIRPANEL active underbody aero on GT R is unaffected — these flaps sit above the airpanel zone. OEM parking sensors and headlight washer apertures are retained. Exhaust note, intercooler intake geometry and brake-cooling ducts are not blocked.

Installation & Reversibility

Install time is 2–3 hours per side for a careful trim shop, or roughly 4–6 hours total including masking, drilling for studs and curing of adhesive. The work involves removing the front bumper from the car (recommended for clean alignment, although bumper-on installs are possible for a confident installer), aligning the supplied paper template, drilling four M5 holes per side, dry-fitting the flap, then cleaning with isopropyl, peeling the VHB tape backing and seating the flap with the studs guiding alignment. The flap then sits on its studs through the bumper skin with internal washers and locknuts. Reversal is possible — the studs come out, holes can be plugged and refinished, the VHB tape releases with heat — but expect light witness marks under the original flap footprint where the VHB lifted clearcoat. Recommended: AMG-certified body shop or Mansory-trained installer; this is not a DIY part because alignment between the two flaps must be symmetrical to within ~2 mm or the asymmetry is visible from straight-on.

Pairing within the Mansory AMG GT programme

The HIGH side flaps work as a coordinated set rather than as a one-off detail. The most natural pairings:

• Add on parts for front bumper (LOW side flaps variant) — the alternative aesthetic; some owners specify both and decide on the car.
• Front lip — closes the front bumper aero language; the lip carries the lower line, the HIGH flaps carry the upper line.
• Wide body kit — the HIGH flap chord aligns with the wide-body fender flare for a single continuous wide line across the front of the car.

Maintenance & Durability

Lacquered carbon needs the same care as a paint surface. Wash with pH-neutral shampoo and a clean lambswool mitt; avoid alkaline traffic-film removers, ammonia-based glass cleaners and stiff sponges, all of which dull the clearcoat and accelerate UV yellowing. A ceramic coating in the 9H/SiO2 family is recommended — six-month to two-year longevity depending on product — and adds chemical resistance against road salt and tar splash. PPF (paint protection film) over the flap front faces is a sensible upgrade if the car sees motorway miles; the front-of-flap is the first surface to take stone chip and tar pickup. If a flap chips through the lacquer, a competent carbon repair shop can re-lacquer locally; deep gel-coat damage means panel replacement, which is straightforward because the flap is a single-piece unit. The HIGH variant does mean less low-speed driveway and ramp damage than the LOW variant — that's the practical advantage of the higher chord line.

Lead Time & Warranty

Lead time is 4–8 weeks from order confirmation, in line with Mansory's bespoke production schedule. Each pair is tracked individually through autoclave cure, finishing and QC. A 12-month warranty against manufacturing defects (delamination, void inclusions, lacquer failure under normal use) accompanies every pair.

FAQ

Q: What's the actual visual difference between the HIGH and LOW side-flap variants?
A: The flap chord line. LOW flaps drop below the front-bumper centre line and emphasise a low, slammed look; HIGH flaps rise above the centre line and emphasise visual width. Same mounting concept, different aesthetic.

Q: Are the HIGH flaps less likely to scrape on driveways and speed bumps?
A: Yes — that's a real practical advantage of this variant. The blade lives well above ride-height level so kerb / driveway scrape risk is essentially zero. The LOW variant is more vulnerable.

Q: Will the HIGH flaps fit my pre-facelift GT S with the Diamond grille?
A: Yes — the flaps bond to the front bumper sides, which are the same on pre- and post-facelift cars. This contrasts with the Mansory grille mask, which is Panamericana-only.

Q: Black Series owner — should I bother with these on top of the existing factory aero?
A: The Black Series already has a comprehensive aero kit. Some owners add HIGH flaps for visual continuity with a Mansory wide-body, others leave the Black Series factory front alone. Aerodynamically the HIGH flaps are mild — they won't conflict with Black Series balance.

Q: Can I run HIGH flaps on one side and LOW on the other?
A: Technically possible, asymmetrically interesting, but not recommended — the car was designed symmetrical and reads strange from head-on. We supply pairs.

Q: How much weight does the pair add over a bare bumper?
A: ~1.1 kg total for the pair, including hardware. Negligible for performance, well below a comparable ABS / FRP add-on.
