How much tire clearance do these flares add?

These over fenders extend your wheel well opening to accommodate wider or lower-offset wheels. Measure your current tire and wheel setup, then compare against your desired upgrade. The flare profile is designed to work with modern street and performance wheel sizes — verify fitment with your specific tire sidewall height and wheel offset against the body line.

Do I need to drill new holes to install these?

No. These flares use factory mounting points on your fender, so you can bolt them directly without cutting new holes. Clean the mounting area and verify all fastener holes align before final installation.

What prep work do these need before painting?

Sand the surface with appropriate grit to scuff the finish, then clean away all dust. Fill any minor surface imperfections if needed, then apply your base coat and clear. Your chosen paint system will determine primer type and application method — follow your paint supplier's specifications for best results.
