08 GT. Just recently changed my front rotors and pads and tie rod ends while I was in there. Then took the car directly to have 4 new tires and alignment done. Well, now I have a vibration, out of balance feel, and occasional brake pulsation that I never had before. Annoying as hell. I took it back to the tire shop and had them re-balance all 4 tires. Better, but still there. I believe its a static balance, not dynamic. Anyway, I may have blown it by buying cheapo rotors and Wagner Quiet ceramic pads from RockAuto. I had EB rotors and Hawk pads prior, and never a problem. Thoughts?

Just a thought but somtimes tire shop hacks use impact wrench on wheels and deform the rotors. I'd torque properly and see if the problem goes away.

Will give that a shot and let you know

Well, I turned the EBC rotors (plenty of meat left) and replaced the cheap ones from RockAuto. I properly torqued all for rims and so far (could only do 65 on local streets) the vibration is gone. I'll know for sure next week when I hit the highway again.

Cool. I always have tires mounted and balanced, then I put them on myself. I know that's not always feasible, so at least tell the shop not to impact them on. Watch them if they will let you, but most shops won't let you in the bay due to insurance concerns.

Did the pads come with any recommended pad/rotor bedding-in procedure? Uneven transfer of pad material onto the rotors can cause vibration as well.

These did not.
