These Solid Rocket wheels are designed after the 6 pin drive magnesium wheels that the Indy Roadsters of the 50s and 60s dominated the track with. The Solid Rocket features the same classic six pin smooth solid design, durable high-tech construction, and are precision-crafted from A356 aluminum. Originally, six pin wheels were held on by a pressure plate and knockoff.
