In 2009, Sparco and O.Z. Racing announced their partnership resulting in an exclusive collection of wheels featuring both companies' Italian design heritage and motorsports background, as well as their commitment to using the highest quality materials and O.E.M construction technologies. O.Z.'s licensed Sparco wheels are TÜV certified and tested using the LBF biaxial test. This rigorous testing procedure runs each wheel through a 15,000 km stress test simulating the driving conditions of the Nürburgring circuit to ensure quality and safety are built into every Sparco wheel.
