Car vibrates when braking, more at higher speeds, less at lower.

Almost 100% sure it's not rotor warp, because rotor warp just doesn't happen. Try bedding in your brakes again. Most likely when you were hard on your brakes, your rotors at one point came to a dead stop before they cooled down, resulting in uneven pad deposits. By bedding your brakes in again, it can possibly remove these deposits.
Stop Tech has great reads about brakes if you want more info.

Simply re-bedding on top of an uneven pad deposit usually does not work and makes the issue worse.

Car Info: MY04 STi some call it a race car
We primarily only stock the StopTech SP pads and use them for our daily brake pad replacement pads
I have them on my wife's car (97 LGT), on my car (02 WRX with front/rear StopTech BBK), on our fathers car (98 forester), on my brothers car (97 Outback), on his wifes car (05 LGT), I also have them on my mom's car (02 PT Cruiser), we have installed them on a G35, etc...You get the idea, we put them on everything that comes through our shop that needs brakes and isn't for track application.
we only stock what we would/will run ourselves and this is why we are comfortable selling them/installing them for our customers daily...

The warped rotor "feel" is usually uneven pad deposits in my experience. Often time you can simply take off the deposits with a sanding wheel without actually turning the rotors. Then you have a fresh surface to re-bed the pads.
Simply re-bedding on top of an uneven pad deposit usually does not work and makes the issue worse.
