Not sure how many of you are aware of this, but StopTech has two great brake upgrade options for the FR-S. One is the inexpensive "Sport Kit" and the other is the powerful "Big Brake Kit". Here's some info and pics on both of them. If you have any technical questions about anything here, just let me know!
---StopTech Sport Brake Kits---
StopTech Sport Brake Kits offer an inexpensive alternative to a true Big Brake Kit. For about $550, you can cover all four wheels with new pads, rotors, and brake lines. Plus, the rotors are available in drilled and slotted/drilled if you want a more aggressive look.
The kits represent a pretty good savings over buying the parts individually as well. Everything works with all your factory equipment, and there is no need to purchase bigger wheels if you don't want to (this is because you retain your factory calipers). The kits are available as front or rear versions as well, if for some reason you don't want to upgrade all four wheels.

---StopTech Big Brake Kits---
StopTech big brake kits for the Scion FR-S are all about extreme looks and stopping power. The front kits start at about $1995 (MSRP) and have two different rotor sizes available: 328x28mm and 355x32mm. The rear kit is priced at $2495 (MSRP) and is only available in a 345x28mm rotor size, but this is huge for a rear application on a car of this weight. Talk about stopping power!!! You'll probably have to upgrade your tires to take full advantage of these kits. I can only imagine the eye-popping g-forces that these big brake kits will provide.

Hope people find this info useful!
