Spacers are used when lowering the front of the car. They sit between the Knuckle Arm and Strut to preserve the original roll steer angle. By correcting the angle of the lower control arm they will restore the original suspension geometry. Sometimes called Strut Spacers or Bump Steer Adjusters, but the purpose is not actually to do either.

Overview

When the car is lowered significantly over standard, the suspension arms are closer to parallel with the ground and the tie rods are inclined up instead of down. Additionally, the steering linkage is no longer optimal.

Roll Centre Adjusters space the steering arms and LCA to their original position.

R31/S12/910 spacers are 80mm but use a large 54 mm locating ring.

These offset kind will also widen your track by moving the strut outward (you could alternatively reverse them to move the strut inward):
