Rear Adjustable-Height Spring Adjusters - E30

replacement/performance/race. These are our new style rear spring adjusters for the E30. The lower sleeves have an inner diameter which is machined to mount flush over the existing spring guide. This setup allows the rear ride height to be adjustable using any range of 2.25" ID springs. (Call us to discuss what spring rate and height would be right for your setup) Included is a urethane upper spring mount. Includes mounting bolt and nut (for various mounting options). SPRINGS are NOT included; but are listed separately (see "related items" below). Machined from billet aluminum T6061 right here in Southern California. Bottom view showing the beveled edge.
