Drop spindles are a great way to lower the front of your Bug, and these 2.5" drop spindles are no exception to that. However, normal drop spindles can also add track width to your car too, thats where these ones are different. They are specifically made to be zero offset, meaning they don't add or subtract anything from your track width but do give you all the lows.
These spindles are for Drum brakes at the front, not discs
These spindles are to fit ball joint car from 66 onwards, however pre 68 cars have a smaller track rod end than cars 68 onwards, so if you have a 66-68 car you will also need the later track rod end for these spindles.
