I seen those. Those are clamps that keep some of the coils together and bring the car lower. Pass on those.
Shims or donuts are round hard rubber pads that the springs sit on. They come in 3 different sizes. The shortest one has a non-functional half round nub or bump on it. The next size has two bumps and the biggest three nubs.
