For an H-Stock Yaris you can:
1. Use R-comps without a class change, or
2. Use 140+ treadwear and run RT supplemental (but not the 195/50-15)

For me, I have a lightweight crank pulley. That puts me in STF by itself. Aftermarket shocks and springs also put me in STF. ST classes do not allow R-comps, and require minimum 140 treadwear. I have aspirations of further mods (gearbox, flywheel, LSD, etc.) that would put me in some kind of Mod class, but that's probably going to have to wait until after graduation.

Flywheel and LSD are ok in FSP, once you change the internal trans gearing you are hosed.
