The Forged ML-10RT is the answer for enthusiasts craving a wheel design that combines classic motorsport styling with modern monoblock forging technology. This wheel was initially developed in the shadows by one of our Senior Engineers exclusively for his BMW E46 M3 widebody race car, and after sharing photos of the prototypes on social media, we received an overwhelming amount of interest from the community to bring it to market. Just like our existing flagship motorsport designs, the ML-10RT was designed from the ground up by our team of in-house engineers and underwent the same extensive FEA analysis and third party testing. It’s made from the highest grade 10K ton forged 6061-T6 aluminum, and utilizes true motorsport blanks, which is a vital component in our ability to deliver vehicle-specific optimizations like maximum concavity, optimal spoke design and critical brake clearance. The end result is a perfect blend of weight savings, added stiffness and strength, all while staying true to the classic motorsport design language we all love. The ML-10RT also sports our reinforced Sprint Spec inner lip and a 1600lb (1650lb for Porsche applications) load rating, which is the same lip design and load ratings we use for our popular Forged Sprint Line.
