This. I run Swift Spec-R lowering springs and RBF600 with no issue. I was on 18x9.5 +45 with 265/35/18 tires.Nothing wrong with tracking the car with just lowering springs. The most important thing to do before any track day is to change your brake fluid to high temp brake fluid such as Castro SRF or Motul 600.
You will not rub unless you run wheels that sticks out too much to the point that rolling the fenders are required.
