Upgrade your Ford Focus ST's performance without killing the warranty - Digital Trends

As petrolheads eagerly await the arrival of the 315-horsepower, all-wheel drive Ford Focus RS , its milder sibling is getting a little upgrade. It’s not uncommon for drivers to upgrade their cars with performance parts, but it’s rare for those upgrades to come with a factory warranty. The 2015 Ford Focus ST is one of the exceptions. Ford says it is legal in all 50 states, and maintains the factory new-car warranty when installed by an authorized dealer. The Blue Oval previously offered a performance exhaust system for the Focus ST, plus a ProCal handset for the Focus and Fiesta ST models that could fiddle with a car’s onboard software by plugging into the diagnostic port under the dashboard. Like the rest of the 2015 Focus lineup, the ST got a handful of upgrades as part of a mid-cycle refresh. The sporty Focus now boasts a redesigned center stack and center console, a flat-bottomed steering wheel, and some tweaks to the exterior styling and suspension tuning. Soon, though, the ST will go from being the sportiest Focus model available, to being the more practical and affordable alternative to the bonkers RS. This will be the first time the RS is.
