2014 Mercedes-Benz C63 AMG — Gloss Black 2-Piece Forged with Polished Lip (19" Staggered)

Engineering Notes

The single most important detail on this build is the 15×32×R14 ball (radius) lug seat. XINGTU's engineers flagged this immediately — Mercedes-AMG uses a ball/radius seat, NOT a taper seat. If a customer mounts taper-seat lug bolts on a ball-seat wheel (or vice versa), the bolt cannot achieve correct clamping load and can loosen under the C63's torque — a direct safety failure. XINGTU's engineers machined the seats to the exact R14 radius profile to match factory AMG bolts.

For the 2-piece construction, XINGTU's engineers forged the spoke face from 6061-T6 with continuous grain flow, then bolted it to a forged barrel using torque-spec, pressure-tested stainless hardware (the visible ring around the lip). The 66.6 mm bore is machined hub-centric so the wheel rides on the hub, not the studs. This 2-piece layout lets the lip depth and concavity be tuned precisely to the C63's arches while keeping every dimension to OEM tolerance.

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
• Ball/radius lug seat profile verified against AMG OEM standard
• Forged 6061-T6, hub-centric machining confirmed

Result

A textbook motorsport-style set—the gloss black face sits deep inside a bright polished lip, with the exposed hardware ring giving it an unmistakable 2-piece pedigree. Built to exact AMG fitment with the correct ball-seat geometry, fully load-rated, and bolt-on ready.
