brake vibration at higher speeds
UPDATE
Another update. Changed out the rear rotors and pads. Used Centric rotors w/ akebono pads. It is now smooth as butter. If you feel vibration in your *** its the rear haha. steering wheel front. Thanks everyone for helping out. I am so happy it finally got solved!
UPDATE
So I changed out the front pads with AKEBONO (heard great reviews) and front OEM rotors. I still have the vibration problem. A little bit about the car: 2007 GS350, 30,000 miles, no accidents or anything. HELP!! This is bugging me. Could it be the rears?
hey I wonder if anyone can help me out. I have some slight brake vibration when braking at speeds of ~50+. New front pads, just resurfaced rotors, just got new tires, balanced and all. And I'm still getting the vibrations. Any help is appreciated!

99 percent of time it's the front rotors. You can cut them but if the are warped too much it will not fully eliminate the problem. Not always that is. Especially with big rotors.
I'm afraid changing the rotor might be the only way.
Worn out suspension components will amplify the problem. But with your mileage I doubt that's the cause.

could it be an improper brake pad bedding? when i replaced my pads i read that if break-in isn't done correctly it could cause an uneven transfer of pad material on the rotor surface which will make the car feel like it has warped rotors.

If the rears weren't changed, and no issue before now, highly unlikley to be them unless pads or disc are shot.
As above, did you bed the pads in properly (many a "how to" on Google)?
Do you tend to put the transmission into neutral or park when stopped, or sit with your foot welded to the brake pedal?
If the latter, then there's a good chance you've warped the discs.
But before presuming the worst, find somewhere quiet(ish) and perform a number of high speed (60-70 mph) heavy braking slowdowns (10 mph) then drive steadily for a while to let them cool fully.
Any deposits causing the problem should be gone.
See how that goes before committing to further skimming or replacing the discs.

Discs are a consumable item too, so no warranty unless you could prove they were in some way defective.
Bottom line, don't sit with your foot on the pedal after long and/or hard braking.
Best to judge speed to coast to lights or put tranny into neutral on flat ground.
You also don't burn the retina out of the driver behind you with your brake lights on full blinding mode!
