How much additional tire clearance do these flares provide?

Rally-style flares extend the fender opening to accommodate wider wheels and tires. Measure your current tire sidewall width and wheel offset, then compare against your desired upgrade size. The flare profile is designed to clear modest wheel fitment increases without trimming or modification — verify your specific wheel and tire dimensions against the fender opening before installation.

Do I need to drill holes or modify the fender to install these?

These flares are engineered for standard factory mounting point locations. You will need to reference your vehicle's OEM fender holes and fastener configuration before installation. Prep the mounting surface by cleaning and sanding, then follow your preferred fastening method — bolts, clips, or adhesive. Check alignment before final tightening.

What should I use to finish the surface?

Sand the surface with appropriate grit to prepare for paint or powder coat application. Use your choice of automotive paint system — single-stage, clear coat, or powder finish all work well on FRP. Prep the surface according to your chosen finish manufacturer's instructions for best adhesion and durability.
