First they came with the wrong clips for the front wheels so the wheels had to be replaced without installation, while waiting for the correct one to arrive I tried installing it the rear ones and found them hitting the wheels when I put them back on. The factory said I might have to move the wheel weights to make it spin and I couldn't get them to understand that it hit the wheel and not the weights and why would anyone need to move the wheel weights to get them to turn install were done correctly.
