These Honda S2000 gears have been shot peened and Isotropic Super Finished in-house at Neat Gearboxes. This leaves the gears around 30% stronger, with the smoothest possible surface finish available. This lowers friction, reduces operating temperatures of diffs and gearboxes, and leads to more power on the ground. Not bad for $349 shipped anywhere in Australia, including chemical hot tank cleaning and crack testing under UV light as well.
