I've got axis ultimates and am pretty happy with them. minor squeeks here and there and they dust like cray cray. I wouldn't recommend them with light/gold wheels if you plan to keep them looking clean.

??? I have used Hawk HPS on many cars,and one of the things I like is that there is almost no visible dust. Also,the dust isn't greasy and it dusts off.

Go for Baer (or GiroDisc) 2-piece rotors.

The dirtier pic is about 4 months, with some clean parts because the wheels were recently rotated at America's Tire Co.

The cleaner one is about 3 weeks.

I wish my pads didn't dust.

FYI - there is ZERO advantage to drilled/slotted rotors. If anything they are less durable than a good solid rotor.

Why is it zero? I always thought it was for cooling the rotors down faster... or gripping the brake pad more =P

The original reason for drilled rotors was not for cooling, but to allow brake pads to out-gas when they got hot. For some early brake pads, they would vaporize and form a small barrier of gas layer (for lack of a better term) between the pad and the rotor. The of porting rotors allowed this gas layer to dissipate
The good news is that pad compounds have improved vastly in the last 30 years and out-gassing is no longer really an issue.

The term cross-drilled is somewhat deceptive. Real world applications are forged or cast with the holes in place. Drilling a standard rotor actually creates stress points which can eventually lead to cracking. Next time to see a Honda Civic with cross drilled rotors, take a close look and you'll see tiny spider cracks forming around the holes.
The Slotted rotor was created to address the spider cracking issue with drilled rotors, the slots do not have the same stress point issues of a drilled rotor. But still, where's the upside?

You rarely see ported brakes on a hi-end race car

I'll throw in another vote for Axxis Ultimates, I paid something like $110 I think for a full set of front and rear pads for my 02 wagon and so far have experienced no noise and very little if any fading. (I'm talking about spirited driving up in the Santa Cruz hills, Highway 9, Highway 35, and that kind of stuff. Haven't taken it to the track yet.)

That said, they dust up my rims to the point where you can't see the original color in about 150 miles (maybe ~20% of those are highway miles). I don't mind too much because the brake dust color matches my car better than the bronze rims
