Do I need special fasteners or hardware to mount these?

These flares are designed to work with standard mounting points common to rear fender panels. Verify your vehicle's OEM attachment holes and gather M6 or M8 bolts (size depends on your car's fastener standard) and any backing plates or clips from your existing fender. Reference your service manual for the correct fastener size and torque specification.

Will these affect my tire clearance or suspension travel?

Fender flares extend outward to cover wider wheel packages and track geometry. Before installation, measure your current tire diameter and sidewall height, then verify the flare extension won't interfere with your suspension at full compression. If running lowered springs or air suspension, confirm clearance at your lowest ride height.

What prep work is required before painting?

Sand the entire surface with appropriate grit to dull the primer finish and improve adhesion, then wipe down with a tack cloth to remove all dust. Fill any transport dings or imperfections with automotive filler, sand smooth, and apply a sealer coat before your base color and clear. This ensures paint bonds correctly and provides even coverage across the panel.
