4. INSTALLATION RECOMMENDATIONS

- Thoroughly clean the hub and wheel bore before installation.
- Install the studs manually—do not use power tools.
- If screwing in the studs, apply a drop of medium-strength threadlocker (blue Loctite).
- Do not lubricate the threads: reliable torque requires dry threads.
- Use a torque wrench: recommended torque for M12x1.25 lug nuts is 90–95 Nm.
- Tighten following a crisscross pattern to ensure even wheel seating.
- Recheck torque after the first 50 km.
