Cusco

Cusco make the plated limited-slip differentials in Betsy, front and rear. We run the front as a 1-way and the rear as a 1.5-way, which is a deliberate pairing rather than a package deal: the front locks on power and frees off the moment you lift so it drags the nose out of a slow corner, and the rear keeps some locking on the overrun to settle the car on entry. They are clutch-type, which means they hold drive when a wheel lifts and they can be rebuilt when the plates wear rather than replaced. On gravel that is the whole argument.
