The Kojin takes the traditional 5-spoke design and adds just the right contours to give it an aggressive tuner look without being too loud about it. The Kojin is built using Enkei's original MAT technology to achieve the ultimate in strength and light weight. The Enkei Kojin is where art and science meet to create the next big step forward in wheels.

Enkei developed a new manufacturing process to produce the next aluminum wheel generation. The Most Advanced Technology (M.A.T) combines one-piece cast wheel technology with a rim forming technology called spinning process. Using this new technology of casting and rim forming by M.A.T process, is critical to improve drastically the material property and strength of the wheels. Rim-Rolled technology shapes the rim to improve material elongation without sacrificing the wheels hardness.

All Enkei wheels are engineered to pass rigorous testing. In fact, Enkei established its own test standard called Spec-E, which is tougher than JWL requirements. Enkei's Spec-E test setting requires a higher drop point in the impact test and 20% more cycles for the rotary bending fatigue and dynamic radial fatigue tests than JWL standards.The Spec-E represents Enkei's confidence in its technology and quality of Enkei wheels.
