Old thread, but figured I'd post for anyone else that may be curious.
I'm a big fan of HAWK. Their ceramic pad option will be the quietest and produce less dust than their HP and HP+ options.

I always prefer to get the same type of pads on all 4 corners for the best result. Also, I'd recommend some good brake fluid for when you take it to the track, such as Ate Typ200. I've used it for many many years as a daily and track fluid with great results.

I also complimented my pads, rotors, and fluid upgrades with SS brake lines, which you can check out here

If anyone has any questions let me know.
