Welcome to the site. Its good to see someone giving some attention to the Yaris, its a nice car.

I would like to ask what is the reason for 'performance' valve springs? From an ecomodding perspective, stiffer valve springs will only increase drive train losses. If you're not increasing your rev limit, I'm not seeing the point to it.
