Will these fit my factory wheels or do I need custom wheels?

These are M12x1.25 metric thread — confirm your vehicle uses metric lug bolts before ordering. The extended 50mm length is designed for vehicles running spacers or deep-dish wheels; standard factory setups may not need this length.

Do I need to tighten these differently than standard lug nuts?

Tightening torque depends on your vehicle's specifications — refer to your owner's manual or service documentation. Aluminum nuts can strip if over-torqued, so use a calibrated torque wrench and follow OEM specs exactly.

Can I mix these with my existing lug nuts, or do I need a full set of 20?

Mixing nut types across wheels creates uneven pressure distribution and vibration. Replace all lug nuts on a wheel together — this 20-piece set covers four wheels with five nuts per wheel (standard configuration).
