These adjustable height rear spring platforms, designed to work with 60mm inner diameter coilover rear springs mounted in the stock spring location at the rear of a BMW E8x (1 series) or E9x (3 and M series). The thread used is self locking once any load is applied.
Made from 6061-T6 aluminum, these are anodized to prevent corrosion. These can be adjusted from a minimum of 0.5" thick to a maximum of 2.75" thick. These can be adjusted independently of each other and is great for corner balancing of your BMW.
Designed to ride on the stop of the spring in an E8X/E9X. The locating stub fits in the factory location and replaces the bulky factory locating stub/hat, which inhibits ride height adjustment with other similar rear ride height adjusters.
