Bilstein sport install question
 

Quick question, the bilstein sports come with 2 front rubber bushings/bump stops? Do I use both or any at all? I included some pics.One has a groove in it and is larger than the non-grooved smaller one. Thanks.

You should check the exploded parts diagram for your car on the free, online Electronics Parts Catalog . . . and how your OEM shocks are currently fitted.

In the future it would help to know the year, chassis number and engine of your car to respond to questions.

Those are bushings that mount the top of the shock to the body. The one on the right goes on the shock, then the shock goes in, then the one on the left goes on top side, then the large washer and nut.
