Available from mountune, the Quaife ATB helical LSD differential for Mk3 Focus ST fits the MMT6 gearbox. A direct replacement for the standard Ford open differential, the Quaife differential transforms your car's performance.
Unlike a conventional plate-style limited slip differential, the Quaife differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation and never locks harshly with a set pre-load of wheel slip across the driven axle.
Instead, the Quaife differential automatically biases the torque away from the spinning wheel, across the axle to a constantly varying degree.
Benefits over a standard open differential:
Quaife differentials are proven in circuit and drag racing, rallying and road use. All Quaife differentials are produced from Corus steel billets, and are CAD-designed and CNC machined before being inspected to ISO 9001 standards.
NetherlandsThe responsiveness and accuracy turning into and driving through the corners is improved big time, amazing! And with standing starts and rolling starts the traction without wheelspin is also much better. Very content with this upgrade!!!

Totally transforms the handling of these cars. Had mine fitted after 3 years. Wish I had done it sooner. However there is one downside - tyre wear. Pre having the Quaife LSD fitted the front tyres lasted 15000 miles (good quality Michelins PS 4's). After the Quaife LSD was fitted I only got 7,500 miles !!. This is what happens if you exploit the road holding the Quaife gives you.. Do I regret having it fitted? DEFINITELY NOT.
