Promotive Spacers 5x120 to 5x112 Wheel Adapters 20mm — BMW

Promotive machines each adapter from 6061-T6 forged aluminum, the same alloy trusted in motorsport applications for its exceptional strength-to-weight ratio. An anodized finish over that substrate means you're getting real corrosion and abrasion resistance — not just bare metal that oxidizes after its first winter. The hub-centric construction is the detail that separates these from cheaper bolt-pattern adapters: by centering the wheel on the hub rather than relying on the studs alone, you eliminate the harmonic vibration that plagues non-hub-centric alternatives.

At 20mm per adapter, you gain a meaningful track width increase on each side, which tightens the visual stance and contributes a modest improvement to lateral stability during cornering. Installation is straightforward for anyone comfortable with a torque wrench and basic wheel work. Each pack includes two pieces, covering one axle — pick up a second set to do all four corners.

For BMW owners who refuse to limit their wheel options to the 5x120 market, these adapters open the door to a significantly broader selection of aftermarket and OEM European fitments without sacrificing the precision fit your car deserves.
