Their price seems pretty low for a set. Not sure how their quality would be due to the price. I am steering toward the Brembo cross drilled or EBC dimpled and slotted:

Don't get the drilled/slotted was easy to crack as my opinion.
OEM was the best, because i don't think you will take the car to track! Am i guest right?
There are two kind of Brembo rotors, one kind of rotor was made in china too.

Default Good Luck...and don't panic stop!

You may be sorry...those things may look like tacos after a serious stop from speed.
I bought a set of Brembo blanks (OEM replacements) for my 96 from buybrakes.com for about $360.
My OE rotors were rumbling after 106K and getting worse.
The new Brembos (made in Italy BTW) smoothed out the braking action very nicely!

I've heard bad things about rotors that are cross-drilled or slotted...namely, their performance in rainy weather (or puddles). Water instead of air, gets trapped in between the holes and the brake pad decreasing brake efficiency causing it to slip...is this true?

I'm gonna bite the bullet and buy Brembos when I get some $$$ after I get my timing belt and water pump done. Of course, now I've been eyeballing some UCF20s/21s in my area now, so I'm weighing my options.

One other aspect to consider about warping rotors, is how hard you stop and let the pads sit on that one area. The rest of the rotor will cool while that area will take longer. If I have to get on the brakes, I'll let the car roll forward so that the area will cool. If I don't have the room, I put it in neutral so the pads will not be exerting force on the rotor. Engage the parking brake if on an slope. It doesn't take long for the heat to dissipate under normal conditions.

YMMV but that's my technique.

Well they are on and wow what a difference. Just had a near fender bender that stock rotors would not have saved me from but these did. The rumbling in the rear is gone and it stops on a penny and a half. LOL. Waiting on it to raid to see if I have any issues. But on dry surfaces these kick ***. I dont drive like a bat out of hell that much so I dont think I will actually have a problem with the warping thing. So yea, the tacos look and taste great. LOL.
