4. INSTALLATION GUIDELINES

- Thoroughly clean the hub and center bore before installation
- Hand-tighten studs only; do not use power tools
- Apply a drop of medium-strength thread locker (e.g., blue Loctite) if threading the studs into the hub
- Do not grease the threads: dry installation ensures correct torque values
- Use a torque wrench: recommended torque for M12x1.25 lug nuts is 90–95 Nm (66–70 lb-ft)
- Tighten in a crisscross pattern to ensure even pressure
- Recheck torque after driving 50 km (30 miles)
