Introducing Signature Reserved SV901! This is a series we spent innumerable hours designing and testing... previously strictly reserved for private racing teams. It is the strongest 5-spoke in the industry. The side of each spoke has been meticulously reinforced and any unnecessary material has been removed. Crafted entirely from aerospace aluminum, a laser focus has been used to minimize weight without sacrificing strength. Signature Reserved is the ultimate track wheel you’ve been waiting for!
