How much tire clearance do these 90mm flares actually add?

The 90mm depth gives you measurable room for wider tires and lowered setups. Verify your exact wheel offset and tire size against your current fender gap before ordering to confirm fitment for your specific build.

Will I need to drill or modify my vehicle to install these?

Installation method depends on your vehicle's OEM mounting point design. Check your factory fender fastener locations and compare them to the flare mounting surface to determine what fastening approach works for your setup.

What wheel offset and tire size range works best with these flares?

The 90mm extension works across a range of offsets and tire sizes — your specific fitment depends on your suspension height and how aggressive your setup is. Reference your wheel offset specs and current tire diameter against the flare geometry to confirm your clearance.
