On the road test I notice a vibration and suspect a bad balance, Therefore removed ALL the wheels again haul them back to the tire shop to have it rechecked. Vibration STILL there! I then removed the spacer kit on the front and found that the two studs with the extended area were pushing on the back of the rotor disc so that it would not set flush against the hub. I can only blame Quality control on Ichaba's part (and myself for trying it anyway) If you purchase Ichaba, CHECK THE STUD'S Alot of misery for a simple oversight
