Storm Motorwerks E46 M3 Stainless SMG Shift Knob - V3

The Storm Motorwerks SMG Shift Knob V3 for the BMW E46 M3 is a CNC machined stainless steel replacement for the factory chrome plastic SMG knob — a component that, against the standard the E46 M3 sets elsewhere, always felt incongruous. The V3 addresses this without abandoning the proportions that make the OEM layout familiar: overall dimensions are retained, while the profile is refined into something considerably more considered.

The design presents a clean, elegant silhouette with machined detailing grooves that enhance its subtle curvature while preserving a characteristic reference to the original form. The surface is finished with the SMG shift pattern engraving, completing the transition from factory plastic to precision machined steel without changing the functional language of the control. Weighing in at 10.6oz, the V3 replaces mass-produced plastic with the solidity expected of a purpose-built component.

The V3 is designed to pair naturally with the Storm Motorwerks SMG Gaiter Ring, available separately, allowing for a cohesive upgrade to the full SMG selector area.
