Do these flares require modification to my wheel wells or suspension?

No modification needed. Verify tire clearance with your current wheel and tire setup before final installation. The 50mm extension is designed to work with stock geometry; measure your existing fender-to-tire gap to confirm adequate space for your specific rolling diameter.

What surface prep do I need before painting?

Sand and prep the surface before applying your chosen finish. Standard automotive paint prep applies — clean any dust, address any imperfections, and follow your paint system's manufacturer guidelines for primer and topcoat compatibility.

Are factory mounting points pre-drilled?

The flares ship ready for you to drill and secure using your vehicle's existing body lines as reference. Test-fit each piece before committing to fastener locations; this ensures alignment with your specific vehicle and gives you control over installation method (bolts, rivets, or adhesive backing).
