Buying Guide
What to check before buying 5×100 to 5×120 adapters:
- Hub-centric design: Prioritize adapters with a precise bore that matches your hub to reduce vibrations and improve alignment.
- Center bore compatibility: Ensure the bore matches or exceeds your vehicle hub size to avoid hub misalignment.
- Stud installation: Note if stud trimming is required to achieve flush mounting, and ensure your wheels have recessed pockets if necessary.
- Thickness vs. wheel clearance: Thicker adapters push wheels outward; confirm there is adequate space for calipers, suspension, and fenders.
- Pattern compatibility: Double-check that the adapter converts exactly from 5×100 to 5×120, or to the intended 5×130 if choosing that path.
- Material and finish: Forged aluminum offers strength with lighter weight; anodized finishes resist corrosion in road use.
