The Diff Check has been developed in order to satisfy drivers needs providing them a device that is able to give a value to the diff hardness during race and test stage.
Diff Check provides data to the drivers that allows them to evaluate or replicate a certain hardness. It won’t be risky anymore to refresh the diff oil to avoid the fear of replicate the same hardness. From now, drivers will have a record that will allow them to have consistency or choose a softer or harder diff. Diff Check is useful for all categories and scales that use oil diffs.
