Do I need to drill new holes to mount these, or do they use existing mounting points?

These over fenders are designed as a bolt-on installation using your vehicle's existing body lines. Reference your OEM body panel fastener locations and mark them on the new fender before drilling. Always verify clearance around door jambs and body lines before committing to hole placement.

What surface prep is required before painting?

Sand the surface with appropriate grit to create a clean, even base for your topcoat. Wipe down thoroughly to remove all dust. Any small voids or imperfections can be filled with body filler before final sanding. The quality of your prep directly affects the final finish, so take your time.

Will these fenders affect my tire clearance or suspension geometry?

Over fenders add width to the body line. Check your tire size, suspension setup, and any lowering springs or coilovers against the new panel profile before installation. Test-fit or measure the clearance between your current wheel and the inner fender lip to confirm fitment with your specific setup.
