It is very rare for a wheel to have the proper center bore for your VW or Audi from the factory. The vast majority of wheels are designed as a universal type fitment, which means they need a hubcentric ring in order to safely and snugly fit your vehicle. With it becoming more and more popular to search old old wheels, and wheels that weren't originally sold for VW or Audi cars, these hubcentric rings might be the final piece of the puzzle for a complete installation.
