The offset may be too high, resulting in the wheels sitting too far inward. This is both ugly and incorrect as the tire can now rub on the inside wheel well, or on suspension components, etc. A wheel spacer will push the wheel out and &#039;correct&#039; the offset. <span class="a-text-bold">Improved Handling:</span>Widens your vehicles wheel base, increasing overall stability and better handling. <span class="a-text-bold">Hardened Wheel Studs:</span>Our 10.9 grade wheel studs are heat treated, offering ultimate strength and corrosion resistance.
