2020 BMW M8 — Brushed Silver Concave 5-Spoke 2-Piece Forged with Polished Lip (21" Staggered)

Engineering Notes

XINGTU's engineers built this as a true 2-piece forged wheel: the brushed 5-spoke face is forged from 6061-T6 with continuous grain flow, then bolted to a separately forged barrel using torque-spec, pressure-tested stainless hardware. This 2-piece layout is what lets XINGTU's engineers tune the lip depth and concavity precisely to the M8's wide arches — something a one-piece casting simply cannot match — while keeping every dimension to OEM tolerance.

On a 1,900 kg twin-turbo V8 grand tourer, the bolted joint is the critical detail: XINGTU's engineers torque each fastener to spec and pressure-test the assembly for seal, so the face and barrel behave as one unit under cornering, braking, and the M8's full torque load. The 66.6 mm center bore is machined hub-centric to the BMW G-platform, so the wheel carries load on the hub rather than the studs — essential on a car putting down this much power. Because the M8 runs a 5x112 bolt pattern (the modern G-chassis BMW standard), the set bolts straight on with no adapter. The brushed-then-polished finish is applied after machining so the spoke grain and mirror lip stay crisp and consistent across all four wheels.

From Design to Delivery

• CMM dimensional inspection (PCD / CB / runout)
• Dynamic balancing on every wheel
• 2-piece hardware torqued to spec & pressure-tested for seal
• Forged 6061-T6, hub-centric machining verified
• Brushed/polished finish QC under controlled lighting before packing

Result

A deep-dish 5-spoke set that gives the M8 real street presence—the brushed silver spokes read as machined-aluminum texture up close, while the polished lip throws a bright ring of light around the rim. True 2-piece construction, lighter than the heavy OEM M8 wheel, fully load-rated, and bolt-on ready.
