The RC-G4 is Enkei Racing Series' design for rally use. It's constructed using Enkei's MAT technology for optimum strength and light weight.
MAT combines Enkei's MAP (Most Advanced Production) and flow-forming forging technology. MAP is a highly automated system. Each process is connected in a single-piece flow system that transports wheels from the melting process, through heat treatment and on to machining. The flow forming process produces a finer, more even aluminum structure, yielding a light yet strong wheel.
In addition to advanced manufacturing, the RC-G4 has been carefully designed for the demands of rallying. The large center area helps prevent debris and gravel from lodging in the brake system, while the many short spokes optimize strength and allow cooling air to reach the brakes.
Enkei's state-of-the-art construction and quality control, combined with carefully optimized design give these wheels excellent resistance to impacts, stresses and damage.
The contour of the barrel and face of the wheel are designed to optimize brake clearance. This allows for the largest possible calipers and rotors within a 15" wheel. Proven in use on Group N rally cars, these wheels are truly race ready!
