Want to dramatically improve your Focus RS overnight? Take advantage of some of our most popular products packaged together for a limited time only!
Unlike a conventional plate-style limited slip differential, the Quaife differential, exclusively available via mountune, 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.
- Differential Installation kit
Fitting hardware set required for the installation of the Quaife ATB differential. All genuine Ford parts, including bolts, seals and bearings.
As torque and power are increased over standard, the Focus RS' PTU casing can fail due to torsional load and strain caused from hard launches and aggressive driving. The mountune PTU Brace Upgrade provides improved rigidity through robust CAD design and features an additional mounting point compared to the standard stamped steel part.
The mountune Focus roll restrictor reduces the amount of engine roll / movement during hard acceleration and gear changing, plus helps reduce 'wheel-hop', particularly when the power output has been increased.
A shorter, crisper shifter throw provides a positive driving experience on the Mk3 Focus. After considerable evaluation and input, mountune's engineers determined the optimum reduction for the Mk3 Focus shifter to be at 25%.
Please note: the price shown for this product includes an overnight installation at mountune HQ in Hutton, Essex and is not transferrable to any other Ford dealer or installer.
