I’ve ways felt like in addition to being an all-around awesome car, the Ford Focus RS also has the potential to be an aftermarket darling. It’s the kind of car that seamlessly blends a modern aggressive look with performance numbers to match. In other words, it’s ripe for the tuning world considering the wealth of modifications that it’s open to. So yes, I’m not surprised that Ford is rolling out a bunch of modified Focus RS models at the 2016 SEMA Auto Show. Even better, one of them comes by way of Roush Performance, considered as one of the best Ford tuners in the business.
