Wobble bolts have a moving collar allowing for Audi and Volkswagen vehicles that have a 5x112 bolt pattern to run wheels that have a 5x114.3 bolt pattern. Wobble bolts allow for the proper centering and securing of the 5x114.3 wheels which open up the possibilities when looking at wheels for your car. 

Before installation it is important to check the following:

 - Proper Center bore of your vehicle and the new wheel

 - Proper shank length for the new wheels on your vehicle (Lug Bolt Safety) 

 - The new wheels take a 60-degree cone seat bolt

Note:

 - Audi and Volkswagen factory lug bolts are 27mm Ball seat lug bolts.
