How much tire clearance will these flares give me?

ETF Tune flares provide clearance for wider rubber and slightly larger diameter tires compared to stock. Verify your wheel and tire fitment against the fender extension before ordering; the added width accommodates most common performance tire sizes used on this platform.

Do these require drilling into the fender or can they bolt directly to existing holes?

These flares are designed to use factory mounting points where available. Check your vehicle's OEM fender structure to confirm fastener locations; some mounting may require minor hole enlargement or new hole placement depending on your specific setup.

What prep work is needed before painting?

Sand the surface with appropriate grit and clean thoroughly before applying your chosen base coat and clear. FRP surfaces bond well with automotive polyurethane and enamel finishes; follow your paint manufacturer's surface prep guidelines for best adhesion and finish quality.
