What bolt patterns and stud sizes are available in Wilwood bolt-on brake kits?
Front kits which include Wilwood aluminum hubs have ½” studs. With a few exceptions, hubs are manufactured to accept both 5×4.50″ and 5×4.75″ bolt patterns. Hats used in front kits are generally drilled to fit over the original OEM studs.
