Enkei NT03RR 18x8.5 5x10042mm Offset 75mm Bore - Gunmetal Wheel

Another Enkei Racing legend has received an RR makeover with Enkei's latest MAT DURA II flow forming rim, the NT03RR. This next generation MAT rim provides improved rim rigidity over the original NT03+M. The wheel's 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. Enkei has adopted two technologies – the Durville die casting and MAT process that ensure cast aluminum wheels have strength comparable to forged ones. In the Durville process, molten aluminum alloy is poured into the mold from its inner rim side, with the disc side facing downward. The alloy is rapidly quenched and solidifies, starting at the disc side, creating a finer metallic structure, significantly enhancing tensile strength, yield strength and elongation. In the MAT process, the wheel rim placed on a mandrel is spun and rolled. This spinning process creates “metal flow” in the metal structure of the aluminum alloy, which is similar to the metal property seen in the forging process. This hybrid process of casting and forging gives wheel high material strength while keep manufacturing cost more affordable than forged wheels. Additionally, it gives greater freedom of design on the wheel face. Enkei’s “Design Capability” ensures its wheels have high stiffness. To maintain high stiffness under great force, the wheel’s cross sectional area in the direction against the force applied needs to be enlarged. However, if the layout, cross sectional shape of the spokes and the rim profile are designed properly, the wheel can maintain high stiffness without adding weight. Enkei’s processing techniques ensure the “strength” of its wheels, and its excellent design capability ensures “stiffness” and “lightness.”
