Quaife ATB differential for the Mazda MX-5 NC. A direct replacement for the standard open differential, the Quaife ATB differential transforms your car?s performance.
A helical diff is similar in design to the Torsen Type 2 differential found in some Eunos Roadsters. They both use worm gears that rotate around a worm wheel to achieve torque biasing across the rear axle. In essence, when one wheel starts to spin faster than the other, a helical diff will transfer more torque to the slower wheel.
This has a dramatic effect on how the car handles, when taking a fast, tight corner with a helical diff your car starts to lean into the corner, instead of the inner, slower spinning wheel giving up, it will start to receive more torque as the outer wheel is spinning faster.
This not only means you?ll feel more confident chucking your car into corners, but also that you?ll be able to get a much tighter and more predictable line coming out of the corner.??Helical limited-slip differentials are great for fast road and track use, they generate no noise, require no maintenance, and are ideal as a fit-and-forget LSD.
