These urethane bump stop spacers can be used to fine tune the bottoming out of your Super Beetle. For example, if your car were bottoming out with the tire rubbing the fender occasionally, install one spacer per strut rod. These spacers are designed to be used with our “lowered” bump stops #87-0258. In some extreme cases, you can use two pairs of the 87-0258 bump stops back to back, with one spacer in between. These spacers are sold by the pair.
