I had a set of EBC Redstuff on my GSR. They did take a bit of heat in em to reach full strength, but they were still fine for driving around town when I wasn't pushing it.

One thing you want to watch out for is that if you use pads with too high a coefficient of friction they tend to feel grabby in normal driving.

Also with that graph, it says nothing about the operating temp ranges of those pads. Once you get into the more aggressive compounds (which is not the case here, I know) there comes a point where your pads won't work right without being heated up first. My EBC Reds weren't extreme in this nature such that I had to make sure they were heated up or they would be unsafe, but the temp range is something worth considering.
