Do I need fasteners to install these, or are bolts included?

The over fenders ship as panels only. Source your fasteners separately based on your chosen mounting method — most builders use stainless steel bolts through the factory holes. Check your existing front-end assembly to determine bolt diameter and length needed.

What prep is needed before painting?

Sand and prep the surface with your chosen grit before applying base coat and clear. The panels arrive unsealed and flat, so surface prep is critical for paint adhesion and finish quality.

Will these fit my current wheels, or do I need wider tires?

The 30MM extension moves the fender outward significantly. Verify tire and wheel clearance by mock-fitting or measuring your current setup against the new fender position. Wheel offset and tire sidewall will both factor into final fitment.
