How much tire clearance do these flares add?

These flares are styled to the Z28 proportions and follow the factory wheel opening line. Verify your tire and wheel diameter against the flare profile before installation—clearance depends on your specific tire sidewall height and wheel offset.

Do I need to drill into the fender or body?

Installation method is determined by your vehicle's mounting points and the hardware you choose to use. Review your factory fender structure and consult a service manual or installation guide specific to these flares to confirm drilling or fastener requirements.

What wheel sizes will these accommodate?

The Z28 flare profile is designed to work with a range of common wheel sizes, but fitment depends on wheel diameter, width, and offset. Confirm your specific wheel dimensions and offset against the flare's contour to ensure proper clearance and appearance.
