This is the description from the website
These spacers have been designed and manufactured especially for the VAG brand of cars. These hubcentric spacers have the VAG 57.1mm centre bore on both the internal and external face. The existing wheel bolts on your current car will be sufficient to bolt these to your car no need for longer bolts.
The spacers are made out of a single block of 100% aluminium.
These spacers are hubcentric meaning they will sit flush on the hub. We dont sell universal spacers or floating spacers as they cause too much fitment issues and vibrations. The spacer will seat securely onto the wheel hub and then directly into the alloy wheel centre bore. This ensures that there will be no issue with steering vibration caused by an unbalanced wheel and hub assembly, which is almost always present when using universal or floating spacers and will inevitably lead to irregular, excessive and expensive tyre wear.
If you have upgraded your brakes with our Porchse/Brembo brake adapters chances are these will be needed to clear the caliper from the wheel.
