Zimmerman makes a very good product. Did you torque the wheels properly? If so this vibration could be coming from the wheels/tires or something in the steering. You can check for rotor runout with a dial indicator to be sure. If you need help from a shop here is a link to find one local to you. https://repairpal.com/repair-shops Alex
