Pulsation while braking..
Pretty much self explanatory... I've changed lower ball joints, axels, brakes, rotors, yada yada yada... Havent changed any operating systems yet, MC or BB nor have I changed Calipers... While driving above like 40 if I put my foot on the brakes my car has a slight vibration and if I'm going about 90 and do the same, it's almost an irratic shake of the front end.. Any ideas.??? Car has stock suspension, but im ordering new setup sometime within next couple days.. I thought maybe it was my suspension, an even though now I think otherwise I still think its a good idea to lower betsy a lil bit.. But anyone have any clues about braking issue..??

you took warped rotors off and replaced with new warped rotors.
YES, they sit on the shelf for long periods of time and will warp, i see it a few times a day, have them resurfaced.

honestly, i thought about that an was like hmmm naa its gotta be something else, but maybe i was wrong.. is pulsating while braking only a rotor issue it wouldnt be like failed caliper or something??

Re: (JDM_SOHC)
Do you have a run out tool? You can use it to verify if the caliper is warped. Or you can have them resurfaced at a local shop.
Have you had your wheels checked for balance? It may be a stretch in such that your shake occurs at 40mph and above. If the tire/wheel were out of balance, it would probably show up at lower speeds. Unless the balance was off where it required enough speed to show itself.

My Rx-7 had a wheel off balance that would only vibrate between 60-80mph. I'm willing to bet you have the same problem. Have your tires checked at an alighnment shop.

Maybe the wheel bearing. My car would shake only above 60, but i felt a pulse in the pedal all the time. Just got the new bearing and now theres no pulse whatsoever.

an out of balance wheel wont cause a SHIMMY WHILE BRAKING.

this is very true, but you would hear the bearing while driving, and since you didnt describe a noise i would rule it out.
