How much tire clearance does this add?

The flares extend significantly outward to accommodate wider tire and wheel combinations. Measure your current wheel diameter and offset against your desired setup, then verify the flare profile clears your chosen package during a test fit before final installation.

Do these require drilling into the body?

No drilling of the original bodywork is necessary. These mount directly over the factory fenders using standard fastening points. Verify mounting hole alignment with your vehicle's existing body structure before securing.

What wheel sizes and offsets will these accommodate?

The flares are engineered to work with a wide range of wheel diameters and offsets. Reference your wheel specifications (diameter, width, offset) and test-fit the flares to confirm clearance with your brake assembly and suspension components before final installation.
