Modification #1: Replace wheel locks with lug bolts!
All VW models come with one wheel lock on each wheel. The wheel lock is a special lug-bolt with a unique "keyed" head that cannot be removed with a normal socket. The theory is that this will prevent your wheels from being stolen - the reality is that this causes owners headache and added expense when they need to change their wheels. Finding a replacement key if the original is lost can be difficult or impossible.
At IDParts we recommend changing the wheel locks out for regular lug bolts the moment you receive the car. This kit includes 4 lug bolts and 4 new caps for the new lug bolts.
