the vibrations i had were the steering wheel shaking 5 to 10 mm in my hands from side to side on flat freeway, all wheels balanced, wheel alignments done and wheel shims in. back on stock rimms, still feel the same shake but no physical shake any more. toyota cant find anything wrong, or professionals either physically but can feel it. no fix so sell the car, unless someone can tell me how to fix it. maching rotors didnt help either (shake was not under braking, just normal driving)
