Can function define the ultimate beauty of form? Our newest Competition Series wheel, the Forgeline GTD1 5-Lug, is a 10-spoke, 5-lug derivative of our race-winning GTD1 centerlock wheel. It combines the latest in advanced wheel technology, including one piece forged monoblock construction, motorsport engineered design, I-beamed spokes, and channeled spoke spans. And it’s engineered to withstand the rigors of top-level endurance racing, delivering uncompromising strength and exceptional deflection stiffness! The GTD1 5-Lug features an open lug center to reduce mass and enable easy access to the lug nuts. And its 5-bolt lug pattern can accommodate most performance vehicle fitments in 18, 19, and 20-inch diameters and a wide range of widths and offsets.
