Available from mountune, the Quaife ATB helical LSD differential for Mk7 Fiesta ST fits the B6 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.
United Kingdom100% one of the best modification I have done to my car so far! Worth the money! Should have come with the car standard!
I’m a little bit late to the party and had my reservations to purchasing the Quaife as obviously it’s not a cheap add on but saying that let me add I had issues with bad under steer prior to having the quaife fitted and even running on fairly cheap tyres I have pretty much lost all of the under steer so where prior to the quaife being fitted roundabouts where mainly a front end slide let off let off let off now are no longer, it also has a noticeable Traction gain putting the power down. A definite recommend for any other mk7 Fiesta ST owner especially if your running an increase in WHP.
A definite big improvement over the standard diff, this is a must have if you're running the M230. Big thanks to Ryan, Fred and the team at Mountune HQ, superb customer service as always.
