mountune® Ford Fiesta ST Performance Upgrades

Get the Power You Want from Your Fiesta ST’s Engine

If you debated buying the Fiesta ST vs the Focus ST when purchasing your hot hatch, you probably chose the Fiesta knowing that you were trading straight line performance for lower weight and better maneuverability. However, by adding some Ford Fiesta ST performance parts, your little Ford should have no trouble keeping up or passing its bigger brother. Ford sold the ST for three model years. The 2014 Ford Fiesta ST and 2015 Ford Fiesta ST are identical, while the 2016 Fiesta ST got an updated Sync infotainment system. Everything else is the same, so our performance parts will fit any North American model.

When you start looking for Ford Fiesta ST performance parts, your first through is probably power. That’s why Mountune offers several ways to get more from your Fiesta’s engine. This includes bolt-on upgrades, like intakes, intercoolers and ECU reprogrammers to get Fiesta ST’s HP up. With Cobb’s Accessport ECU flasher, you can get a tailored calibration that works with different intercoolers, downpipes, blow off valves and fuel types. For more advanced builds, we have short blocks and long blocks built to handle massive amounts of boost. To help you get power to the ground we carry supporting Fiesta ST upgrades, including stronger clutches, limited slip differentials and stiffer engine and transmission mounts. If back pressure is an issue, you can install one of our exhaust systems. Pair a set of new exhaust pipes with our symposer delete kit, and your car will sound better, too.

Get the Handling and Braking You Need for Shorter Track Times and Better Performance

Of course, simply upgrading the Ford Fiesta ST drivetrain components only goes so far. That’s why Mountune carries Fiesta ST upgrades that help your car handle and stop better. We offer Bilstein shocks, as well as our own Clubsport suspension kit that pairs these shocks with springs designed to lower your vehicle and improve handling without sacrificing ride quality. As your Fiesta ST horsepower climbs with engine upgrades, you need to make sure you can reel in your speed with better brakes. That’s why we offer slotted rotors for faster cooling and complete upgrade packages that pair these rotors with high performance pads. Together, these components deliver excellent braking performance, even under harsh racing conditions. Add in a set of braided brake hoses, and you’ll get better pedal feel, improving control.

Want to install a big, free-flowing exhaust? We have stiff exhaust hangers that keep the muffler and pipes from banging against the floor of your car in tight turns. Having trouble with body roll and tire scrubbing? Our bushings reduce lateral movement in the sway bars and rear torsion beam, so your car can maintain its suspension geometry. Want to fit more aggressive tires, or just want to improve the looks of your car? We carry fifteen52 wheels that fit the Fiesta ST bolt pattern in a variety of designs. Using your Fiesta ST for rallying? Add a set of Rally Armor mud flaps, and you don’t have to worry too much about the paint.
