The ZX3-R is a 10 spoke evolutionary design. Each spoke is tapered 10 degrees and extra machining is used to reduce weight even further than the original SX3-R design. Each wheel is built with true forged 6061 T6 centers, 6061 T6 spun rim halves, stainless steel fasteners (titanium fasteners and jet nuts are optional), and feature a powdercoated silver or gunmetal finish with a polished lip. This design is 3 pounds lighter than the standard 3-piece Forgeline wheels. The ZX3-R is available in sizes from 17x7.0 to 19x13. Since each wheel built to order, Forgeline can offer special features like custom offsets, center locking hubs, and a choice of center finishes.
