2018 BMW 5 Series Touring (G31) | 20" 2-Piece Forged · Brushed Silver Center + Polished Lip

Engineering Notes

A square 20x11 ET35 is an aggressive but balanced fitment for the G31—11" of width at all four corners gives the wagon a planted, purposeful stance, and ET35 keeps the face flush in the arch with safe clearance over the front struts. We held the 5x112 / CB66.6 hubcentric bore to BMW's exact spec for a vibration-free fit with no spacer rings—important on a heavy, comfort -oriented touring car. The classic five-spoke center is brushed by hand for a directional satin grain, then sealed, while the independent lip is mirror-polished—two distinct finishes a monoblock can't separate. The two-piece construction bolts the center into the polished lip with torque-spec'd hardware, sealed and pressure-tested for an even-loading interface.

From Design to Delivery

• CMM dimensional inspection on PCD, bore & offset
• Torque-spec assembly hardware, sealed & pressure-tested
• Dynamic balancing on every wheel
• Load-rated to 750kg per wheel

Result

A timeless, premium stance with genuine forged strength—the brushed-and-polished classic five-spoke gives the G31 wagon a clean, sophisticated upgrade, while two-piece construction keeps it serviceable for future refinishing.
