My Budget is X Dollars, What Should I Get? Not everyone has the same budget when it comes to modifying their car, but everyone loves a shiny new part. That’s why we made a list of our favorite mods and parts at every major price point. No matter what you spend, you know you are getting something good. Save up and scroll down to see what we recommend.

When it comes time to replace the clutch on your Focus ST, an opportunity arises to kill a few birds with one dropped transmission. Not everyone NEEDS an upgraded LSD, but will an upgraded differential give your car the potential to handle better? Yes. The internet loves to argue about understeer and necessity when thinking about upgrading the diff, but the fact is: better differential = better grip, and grip is good (if you know how to use it).

What are the best first mods for my Focus ST? Our favorite first three mods for the Focus ST are Access Port, Intercooler, and Rear Motor Mount. Engine management is key at every step of the build, cooling your compressed air will make more power and keep the engine safe, and securing your motor will allow you to put that power down on the road.

Suspension mods can be as simple or as complicated as you make it, and there are plenty of top notch companies taking R&D to the next level so you don't have to get into the weeds with spring/dampening rates. Yes, numbers are important, but unless you are designing full custom setups for your national circuit race car, why not let the engineers handle the heavy lifting? We took four sets of the most popular lowering springs and installed each of them on our 2016 Ford Focus ST to find out exactly what all that hard work and engineering does on the streets. Check out the video below to see what we discovered:

To say we're happy to have XDI around is an understatement. Before XDI, the Focus ST and many of it's other GDI fueled counterparts were limited to the factory fuel systems. Granted, many GDI systems are capable of fairly large flow increases unlike some other port fuel injected vehicles where you have to replace injectors and/or pumps almost immediately if you start modifying. But we all know mild power increases aren't going to cut it for many of us.
