How much tire clearance does this add?

C Spec flares extend the fender line outward to accommodate wider tire and wheel setups. Measure your current tire sidewall and rim width, then verify clearance against the flare profile before installation.

What wheel offset and size does this support?

These flares are engineered to work with factory and modest-offset wheel sizes. Reference your wheel offset and tire diameter specs against the flare opening—wider wheels and lower offsets require more clearance verification.

Does drilling or fastening to the original fender structure require special prep?

Proper mounting prep depends on your vehicle's specific hole locations and fastener pattern. Inspect the OEM fender attachment points and sand the mounting surfaces before securing the flares—your service manual will confirm fastener locations and torque values.
