FS.23 22 inch Black Diamond Mansory for Mercedes-AMG S63E

Mansory FS.23 Black Diamond Wheel for Mercedes-AMG S63E

Where the FD.15 wheel is Mansory's flagship split-spoke design with axle-specific FA/RA variants, the FS.23 Black Diamond is a different aesthetic register entirely — a single-pattern spoke design where the visual interest comes from the surface treatment rather than the spoke geometry. "Black Diamond" describes the finish: a gloss-black painted face with the spoke edges, rim-flange band, and centre-cap surround precision-machined to a mirror-bright contrast that catches reflected light along their diamond-cut facets. The result is a wheel that reads dark and disciplined from a distance, but resolves at close range into a precise interplay of black-painted surfaces and bright-cut accents. On a 2,510 kg AMG biturbo V8 PHEV saloon the wheel is forged to the same load-handling brief as the FD.15 — but its visual project is to add chrome-like reflectivity within an otherwise blacked-out wheel register, which is the right register for AMG Night Package cars in particular. Universal-axle (front and rear use the same SKU pair). It is part of the parent Mansory Carbon Fiber Body kit set for Mercedes-AMG S63E.

Construction & Materials

Diamond-cut accents demand a different production sequence than a uniformly painted or polished wheel — the spoke edges are machined to mirror finish at the same time as the spoke face is painted gloss-black, then a UV clearcoat is applied over both surfaces to lock the contrast.

• Forged 6082-T6 aluminium billet, monoblock construction
• Multi-axis CNC machining, including precision diamond-cut facets at spoke edges
• Diameter 23"; widths: 9.5" (front), 11" (rear) — pair-matched at production
• PCD 5x112; centre bore 66.5 mm; offset ET 35 (front) / ET 30 (rear)
• Painted gloss-black face, diamond-cut spoke-edge contrast, painted black centre cap
• UV clearcoat over both painted and machined surfaces for lock-in
• Mass per wheel: 12.0–13.5 kg depending on axle position
• Spoke pattern: ten-spoke single-piece design (not split, unlike FD.15)

Design & Visual Function

From a normal viewing distance — say, ten metres — the FS.23 Black Diamond reads as a uniformly dark wheel that fills the wheel-arch volume with a low-reflectivity surface, in keeping with AMG Night Package aesthetics. As the viewer approaches, the diamond-cut facets at the spoke edges, rim-flange band, and centre-cap surround start to pick up reflected light from the surroundings — at first as fine bright lines, then as defined chrome-bright bands as the viewer reaches arm's length. This range-dependent visual character is what distinguishes the Black Diamond finish from a uniformly painted black wheel: the wheel changes character with viewing distance.

The painted gloss-black face is the visual mat for the diamond-cut accents to read against. Sunlight catching the centre-cap surround at oblique angles produces a defined chrome-flash that is absent from any monochrome black wheel. Cabin lighting at night — particularly the AMG Multibeam LED arrays at the front and the OEM rear-light cluster at the back — reflect off the diamond-cut facets and give the wheel a subtle nighttime sparkle.

For owners specifying the AMG Night Package or AMG Carbon Package, the Black Diamond's gloss-black painted base coordinates exactly with the AMG-spec blacked-out trim across the body, while the diamond-cut accents add a deliberate refined detail without crossing into the visual register of a fully chromed wheel.

Compatibility & Fitment

Engineered for Mercedes-AMG S 63 E PERFORMANCE (W223), 2023+, long-wheelbase saloon. Universal-axle SKU pair (front and rear in the same order). PCD 5x112, centre bore 66.5 mm. Offsets: ET 35 (front), ET 30 (rear). Compatible with AMG iron-brake and AMG ceramic-brake packages. AMG Night Package cars are the natural pairing for this finish; AMG Carbon Package cars also coordinate well. The OEM TPMS sensors transfer to the FS.23 wheels during install. Mansory's lowering suspension is the recommended pairing to set the wheels in the optimal arch-fill position.

Installation & Reversibility

Plan 75–95 minutes for the four-wheel set on a hoist with one technician. Required tools: OEM-pattern wheel-bolt torque wrench, 17 mm socket, anti-seize compound, OEM AMG-spec wheel-balance machine. Workflow: lift the car, remove OEM wheels, transfer OEM tyres or fit new at OEM specification, balance to OEM specification, mount the FS.23 wheels using OEM-pattern bolts at 130 Nm. Reversibility is full — OEM wheels can be reinstalled at any time.

Pairing within the Mansory Mercedes-AMG S63E programme

Most often combined with the Lowering suspension for the optimal arch-fill stance, with the Side skirts lip for visual continuity at the wheel-arch-to-rocker transition, and with the Diffuser for a coordinated rear-end carbon and bright-accent programme.

Maintenance & Durability

Diamond-cut accents are the most maintenance-sensitive part of the wheel — the precision-machined surfaces are protected by the UV clearcoat but they will dull over years if cleaned with abrasive products. Use only pH-neutral wheel cleaner, applied with a plush mitt, never an abrasive sponge. Apply a ceramic wheel sealant quarterly to maintain the clearcoat's hydrophobic life. Avoid acid-based wheel cleaners absolutely — they will haze both the gloss-black painted face and the diamond-cut accents within months. Stone strikes on the wheel face can be polished out with a fine cut compound; deeper damage to the diamond-cut accents requires re-machining and re-clearcoating, which is a wheel-repair-specialist procedure rather than a body-shop job. Cosmetic-finish lifespan: 7–9 years with routine ceramic-sealant care, longer in low-mileage cars.

Lead Time & Warranty

Production turnaround: 7–9 weeks for the four-wheel set. The diamond-cut machining sub-process and the UV clearcoat over both painted and machined surfaces add roughly two weeks to the build window relative to a uniform-finish wheel. Custom finishes (gunmetal Diamond, brushed-bronze Diamond) add roughly two weeks. Warranty: 12 months against manufacturing defects — forging integrity, diamond-cut dimensional accuracy, clearcoat adhesion at the painted-to-machined transition, OEM TPMS-port dimensional accuracy — running from delivery date. Outside warranty: stone strike, kerb-rash damage, finish degradation from acid-based cleaners.

FAQ

Q: Is the Black Diamond finish a paint or a stain on the bare aluminium?
A: It is a paint over the forged aluminium, with the diamond-cut accents machined to mirror finish, and a UV clearcoat over both surfaces. Not a chemical stain.

Q: How does the FS.23 differ from the FD.15 wheel design?
A: FS.23 is a single-pattern ten-spoke design where the visual interest comes from the surface finish; FD.15 is a split-spoke design with FA/RA front-and-rear variants where the visual interest comes from the spoke geometry. Different design philosophies for different aesthetic preferences.

Q: Will the diamond-cut accents lose their brightness over time?
A: With proper care (no acid cleaners, ceramic sealant routine), they hold their factory brightness for 7–9 years. Acid-cleaner exposure can dull them within months.

Q: Are the front and rear wheels different SKUs?
A: They are different widths and offsets but ship as a paired four-wheel set under a single SKU order. The visual register is consistent across all four corners.

Q: Will the wheels work with run-flat tyres?
A: Yes. OEM W223 saloon's run-flat tyres at OEM-AMG specification fit the FS.23 rim flange.

Q: Can the wheel be ordered with a coloured logo on the centre cap?
A: Yes. The OEM-AMG centre cap is supplied black-painted with a Mansory mark; custom centre-cap colours (red, white, contrast accent) are available on order.

Q: How does the diamond-cut catch light at night?
A: Streetlights and passing-headlight beams reflect off the polished facets at oblique angles, producing a defined twinkle that is visible from a few car-lengths away. The effect is more emphatic at low speeds where viewing angles change rapidly.

Q: Is the wheel safe for sustained autobahn pace?
A: Yes. The forged construction is rated for the AMG biturbo V8 PHEV's full top-speed envelope; the diamond-cut surface treatment is purely cosmetic and is unaffected by sustained high-speed running.

Q: Will the diamond-cut accents wear from sustained tyre-flex at the rim flange?
A: No. The accents are at the spoke edges, not at the rim flange itself. The rim-flange band is also machined but in a different geometry that does not contact the tyre bead.
