Sorry to bring this thread back from the dead but if you guys are still active and are still curious, yes you can use focus suspension. Here’s my 2014 with Godspeed coilovers for a focus of equivalent year. Wheels are Konig ampliform. The rear springs are adjusted as high as they go unfortunately due to the low spring rate. I’m currently talking with Godspeed to see if they offer a stiffer spring for the rear so I can raise it up in winter.
