I've been *very* happy with Porterfield R4-S carbon-kevlar pads for street use, but they are NOT cheap (2x-3x the cost of most other pads). They seem to wear very well, much better than I expected, with fairly low dust. While I really like the feel (good initial bite, good modulation), they may need a little more muscle for hard stops when cool... doesn't bother me a bit but if your wife/girlfriend drives the car, they might notice it.
