You can get the NX brakes which aren't much larger in diameter than the SE-R brakes but much thicker, or you can get a kit from someone like fastbrakes.

I recently helped install the FastBrakes kit and it is high quality.

Both are good option, but it depends on what you plan on using your car for.
