Another Enkei Racing legend has received an RR makeover with Enkeis latest MAT DURA II flow forming rim, the NT03RR. This next generation MAT rim provides improved rim rigidity over the original NT03+M. The wheels iconic brace ring evenly distributes stresses on spokes to help rim rigidity even further, giving NT03RR superb cornering and steering response capabilities. Dynamic design with concave rear face offers a beautiful, yet powerful form to complete any true racing setup. The NT03RR is offered in sizes ranging from 177 all the way up to 1811 with a variety of bolt patterns and concaveness profiles. Similar to the GTC01RR and RS05RR, the NT03RR is available in three different concave faces. MAT Technology 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. SPEC E 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. Enkeis 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 Enkeis confidence in its technology and quality of Enkei wheels. Sizes 17 and 18 Matte Gunmetal Spec E Inspected MAT Process
