2024 BMW M2 G87 — Gloss Black Forged Monoblock with Carbon Fiber Outer Ring (19" Front / 20" Rear)

Engineering Notes

Carbon fiber attracts attention first, but it is not the part carrying the vehicle load. On this design, the outer ring is a bolt-on decorative component fitted around a forged monoblock wheel. Cornering, braking and impact loads remain supported by the forged 6061-T6 aluminum structure underneath. Keeping that distinction clear makes the product description more technically accurate and avoids presenting the ring as a structural carbon barrel.

Front wheels measure 19×9.5, while the rear moves to 20×10.5. ET20 is listed for all four positions, so the visual progression comes from the increase in both width and diameter rather than a change in offset. PCD is 5×112 and the center bore measures 66.6 mm.

A 15×32×60° taper lug seat forms another part of the G87-specific specification. The current wheel is machined hub-centric, with the bore and fastening geometry checked before production is completed.

At 12.8 kg per wheel, all four retain the same listed mass despite the rear being one inch larger in diameter and one inch wider. Gloss black keeps the dense mesh face visually unified; carbon fiber then creates a clear outer boundary with a very different surface texture.

From Design to Delivery

• CMM dimensional inspection (PCD / CB / runout)
• Dynamic balancing on every wheel
• Forged 6061-T6, hub-centric machining verified
• Taper lug seat profile verified against G87 OEM standard
• Carbon ring fitment & fastener torque checked before packing

Result

Gloss black makes the mesh center appear compact and technical, while the carbon ring visually expands the wheel toward its outer edge. The two materials remain clearly different instead of trying to imitate one continuous surface.

Staggering 19 inches at the front and 20 inches at the rear also suits the wheel's layered appearance. Size progression gives the rear more presence, while the carbon ring reinforces the perimeter on both axles without adding a second painted color.

Carbon Is the Accent, Not the Structure

That distinction deserves its own place in the content because it is one of this wheel's most unusual details.

Forged aluminum forms the monoblock face and barrel. Carbon fiber sits outside that structure as a removable decorative ring. Buyers therefore get the visual contrast of carbon without the page implying that the load rating depends on a carbon structural barrel.

Staggered in Diameter and Width

19×9.5 Front

Front dimensions keep the wheel at 19 inches, giving the nose the smaller of the two diameters while retaining a relatively broad 9.5-inch width.

20×10.5 Rear

Rear sizing adds one inch to both diameter and width. The result is a more substantial rear profile without changing the ET20 offset used across the set.

Why the Mesh Face Works With Carbon

A simple five-spoke center might make the carbon ring visually dominant. Here, the dense mesh pattern gives the center enough detail to hold its own.

Gloss black also keeps reflections controlled across the many narrow spokes. Carbon weave then provides texture at the outer edge, creating contrast through material rather than relying on a brighter paint color.

Vehicle-Specific Machining Still Matters

PCD, center bore and lug-seat geometry remain part of the engineering regardless of the decorative carbon feature. Xingtu develops the wheel around those fitment details first, then applies the selected surface and outer-ring treatment.

Another G87 with different requirements can be reviewed from its actual wheel and vehicle specifications rather than assuming this 19×9.5 / 20×10.5 arrangement is universal.

1. What sizes are used on these BMW M2 G87 forged wheels?

Front sizing is 19×9.5, while the rear uses 20×10.5.

2. Is the carbon fiber ring structural?

No. The page specifies that the carbon outer ring is decorative. Structural loads are carried by the forged aluminum monoblock.

3. How much does each wheel weigh?

The listed wheel weight is 12.8 kg at all four positions.

4. What offset is used?

ET20 is listed for both front and rear wheels.

5. What bolt pattern and center bore are specified?

This set uses a 5×112 PCD with a 66.6 mm center bore.

6. What type of lug seat does the wheel use?

The current specification lists a 15×32×60° taper seat.

7. Can the wheel be ordered without the carbon ring?

The current page describes the carbon ring as an optional styling element, so another specification can be developed without making it part of the structural wheel.

8. Can another G87 use different front and rear dimensions?

Yes. Width, diameter and fitment should be confirmed against the individual car and its intended setup before production.
