You can now take a look at all the official upgrade parts that Toyota will produce for the GR Yaris. A video showing all the stuff is also available. Right now everything is in Japanese but at least translating the first site is no problem.

Prices are decent too. I know other manufactures who would ask a lot more for all of this.
There will also be an online event on September 16th in celebration of the GR Yaris launch.
