The Aluma Star 2.0 Rear Wheel Center 5-4.5 by WELD Racing is engineered for serious racers and performance enthusiasts who demand precision engineering in every component. This rear wheel center hub is purpose-built for vehicles running a 5-lug bolt pattern with a 4.5-inch bore, making it ideal for high-performance street cars, road course competitors, and dedicated track platforms.
