All of our hardware options (if applicable) are available at no charge on all of our modular wheels, with only a few exceptions for styles with non- compatible spoke layouts. Modular wheels are constructed using 40 fasteners, so the 20|20 option is built with half of the assembly bolts reverse mounted and half as “through bolts” showing 20 exposed bolts on the face of the wheel. 20|20 construction is perfect if you want to showcase the modular construction of a wheel but want a sleeker aesthetic. The blind option uses reverse mounted assembly hardware which is not visible when the wheel is mounted. When used with our AP2 configuration, this option creates a monoblock aesthetic without sacrificing any fitment or concave profile flexibility. Using blind hardware results in a modern, clean look. The exposed option makes all 40 assembly bolts visible, perfect for clients that want a classic look or a way to add a color contrast on their wheel. Chrome bolts are standard but can be finished in a custom color to easily add contrast or match your lip, center, inner, brake caliper or car color.
