The mounting insulator is located between the Upper Strut Bearing and body in the front, and the Upper Strut Spacer and body in the rear. If you notice a knocking or banging sound during sudden suspension travel, such as when you hit bumps in the road or go over speed bumps, these insulators may be the culprit.
**If used in the rear of a 280Z this will lower the vehicle approximately 1/2".** The original 280Z rear strut mount insulator is discontinued.
