Does this knob come with an adapter for my shifter?

The knob assembly ships as-is. Test-fit it on your shifter post first — 50mm is a common diameter and typically threads or press-fits onto most manual shift linkages. If your shifter requires a different size or adapter, you may need to source that separately.

Will the neo chrome finish scratch or tarnish over time?

Neo chrome is a durable plated finish, but it will show swirl marks and fingerprints with normal use. Wipe it down regularly with a soft cloth to keep the shine. Avoid harsh cleaners or abrasive pads — mild soap and water work best.

Is this knob weighted, and does it feel solid when shifting?

Yes, the cast ball design carries mass, which gives solid feedback and reduces shifter slop compared to hollow alternatives. The heatsink fins don't affect shift feel — they're purely for heat management and aesthetics.
