Do these work with my current wheels, or do I need special hub adaptors?

These fit standard M12 x 1.5 hubs — no adaptors needed. Verify your current lug hole pitch matches M12 x 1.5 before ordering; some aftermarket wheels use different thread sizes.

Will the spline design hold the wheel tight, or do I still need a torque wrench?

The spline locks the nut to the hub so it won't spin off, but torque to your vehicle's spec is still required. Check your service manual for the correct foot-pounds — this prevents bolt stretch and wheel loosening over time.

How long will the gold finish last before it fades or corrodes?

Anodized aluminum is sealed against salt, moisture, and UV. In normal use, the finish holds color for years. Coastal or heavy winter climates may dull it faster, but the structural integrity stays intact.
