I have Utlimates on as my street setup. The same pads I had on in OH. There a great pad. I haven't had the chance to really put the heat to them, though. We all know OH wasn't very taxing on the brakes....lol.
I'll use these as my rain setup in GA, if need be. As Mcarp mentioned, they remind me of the HP + pads in terms of feel and friction. Like most pads in this category, they dust quite a bit and squeal on light braking.
