Buying Guide
Key considerations for selecting 5×120 to 5×100 adapters:
- Hub Centric vs Lug-Centric: Hub-centric designs minimize vibrations and improve alignment; look for a precise internal bore that matches your vehicle’s hub.
- Center Bore Size: Ensure the adapter center bore matches or is slightly larger than the hub bore. A tight fit improves centering; a loose fit can cause vibration.
- Thread Pitch and Stud Length: Verify M12x1.5 vs M12x1.25 and whether factory studs require trimming. Incorrect stud remaining length can cause safety issues.
- Thickness: Adapter thickness impacts offset and wheel clearance. Common thickness ranges are 15–25mm; choose based on desired fitment and wheel clearance.
- Material and Finish: Aluminum adapters with anodized finishes provide corrosion resistance and durability for daily driving and performance use.
- Warranty and Fitment Verification: Confirm compatibility with your vehicle’s make, model, and year. If in doubt, ask the seller or consult a professional.
FAQ
