How much tire clearance does this add?

The WRC flare profile extends the fender opening to accommodate wider tire-and-wheel combinations. Measure your current tire outer diameter and sidewall width, then compare against your desired wheel and tire package — the flare geometry will give you the additional clearance envelope. Verify fitment against your specific wheel offset and suspension setup before purchase.

Do these require drilling into the body?

No. The flares are designed to mount at factory attachment points, so you won't need to drill new holes into your frame or fenders. Your existing mounting locations will secure the set without permanent modification.

What wheel sizes and offsets will these work with?

The flare extension accommodates a range of wheel diameters and offsets, but the exact fit depends on your suspension geometry, ride height, and tire sidewall profile. Reference your chassis specifications and compare your wheel offset and diameter against the new flare boundary to confirm clearance.
