They are ideal for applications such as drag racing or drifting, where it is necessary to apply equal torque to both wheels and optimize acceleration potential.\u003c\/p\u003e\n\u003cp\u003eUnlike factory or aftermarket mechanical LSDs, which can crack or break under the grueling conditions of motorsport, Speed Tek spools offer superior durability.\u003c\/p\u003e\n\u003cp\u003eWeighing less than 5 kg, these units provide significant performance benefits. Reduced weight means less force is required to rotate the mass, resulting in improved acceleration and less stress on the drivetrain.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatible with JZA70 Supra, JZX90\/JZX100\/JZX110, 86 (ZN6), BRZ, etc.\u003cbr\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe product is nitrided after the machining process is complete.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eWhat is nitriding?\u003cbr\u003e\u003c\/b\u003e\u003cspan\u003eA heat treatment process that diffuses nitrogen into the surface of the metal to harden it. These processes are most commonly used for low-carbon, low-alloy steels. They are also used for medium-carbon steels, high-carbon steels, titanium, aluminum, and molybdenum.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003eWhat are the benefits of the optional Isotropic Superfinishing?\u003cbr\u003eIt is a surface finishing process that creates a highly smooth surface with minimal roughness. It helps extend the life of steel chromoly shift forks and allows them to operate more smoothly.\u003c\/p\u003e\n\u003cp\u003eBy creating an extremely smooth surface, it reduces friction between the shift forks and other components.
