How much tire clearance does the 40MM extension actually add?

The 40MM width gain lets you fit wider wheels or run a lower suspension stance without interference. Measure your current wheel width and offset, then verify clearance against your brake caliper and suspension geometry before final fitment.

Do these flares require drilling into the body?

Mounting points align with factory body lines. Reference your vehicle's existing hardware attachment points and fastener locations to confirm your installation method—most setups use existing holes or bolt directly to the fender without additional drilling.

What wheel sizes and offsets work with these flares?

The 40MM extension accommodates wider fitments than OEM. Cross-reference your wheel diameter, width, and offset against your suspension height and brake caliper clearance—the flares protect the body, but final fitment depends on your complete wheel and suspension setup.
