In other words, if you were to use your micrometer to measure the thickness of the rotor, it would be exactly the same along the annulus of the rotor?
Have you read the article that I linked to?

Everything I've heard and read from reputable person(s) agrees with Steppin Razor and I've done quite a bit of research on this, because this is the only issue I have with my RS.
I put EBC Greenstuff pads on the front and had my stock rotors turned 2x before purchasing cross-drilled Brembo's. I'm having the same issue again with the EBC's on the cross drilled Brembo's and I'm not sure what to do about it.
I'm using Valvoline Synthetic brake fluid and have ss lines at all four corners. I do brake for hard and short bursts, but I use the e-brake at stop lights and even down shift to 3rd gear normally when coming to a stop. I do not have any other symptoms that I have noticed.
I'm open to other suggestions if anyone has a good one!

The single recurring theme with all your problems is EBC. I'm not saying that because we don't sell them, I'm saying that because I have personal experience with the compound. While it MAY be okay for very passive road driving, it is absolutely not to be used for any type of performance-oriented driving.
Either clean your current rotors up or get a new set, and as long as you use a decent set of pads and bed them in properly, your problems will be solved.

"Warping" Is a loose term, what I was understanding was that brakes can be extremely hot (to the point of blueing) and then you can stop at a stop light and have the brakes applied and make a low point in the rotor. To me that is warping but maybe it is another term.

my L shakes like a bastard while at "high" speeds (60 mph). the L has never been over 90 before. still shakes really bad. the dash and glovebox rattle around. its quite annoying. i checked the pads and they seem ok. looks pretty normal. my brakes also squeak a lot when im going really slow (like in parking lots and such) and then i lightly apply the brakes.

svek, you might want to get an alignment done or get your wheels reballanced if you haven't in a while... Any sort of unballance motion becomes exponentially exagerated at high speeds.

get a stage 2 upgrade kit from stoptech.... i just did, and it is AWESOME. the difference between warped stock rotors to the slotted stoptechs is amazing! and at about $100 a pop if all you wanna do is front rotors (the rears were fine, the stock pads still had plenty of material on them and im at 73000 miles!) and pads your looking at $300 and an evening of getting brake dust all over you. Not bad for such a huge difference in braking. Oh and Axxis Ultimate pads roxor your boxors
