Specialist tuner Mountune has announced the first details of its ‘Phase 1’ upgrades for the new Ford Focus RS. A variety of parts are available to buy now, with an entire Mountune Performance package coming soon.

Initially, owners wanting more from their Focus RS will be offered a selection of ‘easy first-off modifications’ designed to build on the already potent hot hatchback. Mountune is claiming improvements in induction noise, as well as shorter gearshifts, reduced engine movement, and a boost in straight-line speed.

The Mountune store is currently listing upgraded hoses and roll restrictors, as well as lightweight 19-inch OZ Racing wheels and a high flow air filter. Michelin Pilot Sport Cup 2 tyres and a Quaife Differential are also available. You can even buy a yellow gearknob, Mountune floor mats and ‘Dynamic Side Splash’ stickers for the sills.

The Ford Focus RS Mountune will eventually gain a full Mountune Performance upgrade kit – much like that available on Ford’s Fiesta and Focus ST models. David Moore, General Manager of Mountune Performance says the complete package is close to completion, but that sign off is “not yet complete”.

“The Ford Focus RS is one of the most exciting and dynamically advanced Ford road cars”, he said. “For our engineering programme to reliability extract more power and torque – whilst ensuring proper interaction will all the car’s dynamic modes, suspension and launch control – has necessitated an extended durability sign-off”.

Mountune has tested all its performance parts on road and track – including at the gruelling Nurburgring circuit in Germany. The kit has been finalised after tens of thousands of miles of testing, data collection and high-speed work, with bosses ensuring improvements in power and torque – as well as a reduction in the car’s 0-60mph time.

The full Mountune Performance kit will be revealed soon, along with prices and exact details. Only then will it be available for purchase and installation. A full MR300 kit on the Focus ST costs £2,725, meaning we expect a complete RS package to cost closer to £4,000.
