How much tire clearance do these flares add?

The 40mm extension provides moderate clearance gain for moderately wider tire setups. Verify final fitment against your specific wheel diameter and offset before installation — measure from the inner fender arch to your tire sidewall to confirm adequate gap.

Do I need to drill or modify the fenders to install these?

These flares are designed to use factory mounting points where available. Check your vehicle's OEM fender attachment locations before starting work — some drilling or fastener modification may be necessary depending on your setup.

What wheel offset and size are compatible with these flares?

Compatibility depends on your specific wheel diameter, width, and offset. Measure your current setup and compare against the 40mm clearance this kit provides. FRP can be carefully trimmed if minor rubbing occurs during fit-up, giving you adjustment flexibility.
