The new Ford Focus RS is a hot hatch that is sure spawn a wide offering of aftermarket performance offerings ranging from cold air intake systems all the way to more extensive engine and transmission upgrades. Only being around for a short time, model-specific aftermarket performance options are far and few between right now, but Mountune USA has finally released a decent list of upgrades known as Phase 1, which undoubtedly means there will be more to come.
Each piece of the Phase 1 tuning kit can be bought separately. The upgrade list starts out with a Mountune high-flow air filter and high-flow induction hoses that are priced at $59.00 and $69.00, respectively. Next on the list is the ultra-high-performance silicone boost hose kit that retails for $315. More in-depth bolt on parts include a roll restrictor for $159, which is basically a stiffer rear engine mount that cuts back on engine movement during launch, shifting, and heavy acceleration. There is also a quick-shift upgrade which replaces the standard shift arm on the transmission for $199.
There are two other options, which are a little more expensive. First on the list is the OZ Leggera wheels, which as you can see in the attached video, offer just enough clearance for those large RS calipers on the front axle. The wheels are 3.7 pounds lighter than the stock OE wheels, are ET45 offset, and are 19-inchs in size. The wheels are priced at $485, but that doesn’t include tires, which are sure to set you back at least that much, if not more. The big news in the Phase 1 tuning kit is the $1,099 Quaife ATB differential that helps maximize traction, minimize wheel spin and torque steer, and is maintenance free. Mountune USA hasn’t announced an installation kit for the differential, but for the Focus ST, the installation kit runs $124.
