How much tire clearance does the 75 MM width actually provide?

The 75 MM expansion per side eliminates rubbing for most wheel-and-tire combos up to moderately aggressive offsets. Measure your current wheel lip-to-fender gap and compare against your new tire sidewall — if you're gaining 75 MM on each side, you have solid margin. Exact clearance depends on your wheel offset and suspension geometry.

Do these flares require drilling into the body?

No drilling required. These flares bolt to the factory mounting points on your vehicle. Use the existing holes and fastener pattern — the integration is clean and OEM-aligned.

What should I do before priming and painting?

Sand the surface to your chosen paint spec, clean with a tack cloth, and apply your primer and topcoat. FRP accepts standard automotive paint finishes. Consult your paint supplier's recommendations for prep steps specific to fiberglass substrates.
