When you demand the very best, look no further than Enkeis racing series. Most Advanced Technology Enkei developed a new manufacturing process to produce the next generation of aluminum wheels. Most Advanced Technology (MAT) combines one-piece cast wheel technology with a rim-forming ?spinning_ technique. Use of this new technology of casting and rim forming, is critical to drastically improve the material properties and strength of wheels. In addition, Enkeis rim-rolled technology shapes the rim to improve material elongation without sacrificing the wheel's hardness.
