Why did you cut your lowering springs? Lowering springs, or any spring for that matter, shouldn't be cut if you want to retain some comfort.
Lowering springs will always lower comfort to some degree depending on the application and type of spring. If you want the most comfort from your spring, opt for Progressive Rate lowering springs.
Progressive Spring Rate Definition: A spring with an increasing spring constant. For example, if the first inch of spring motion requires 100 pounds of force, the second inch would require more than an additional 100 pounds, and the third inch would require still more. Progressive-rate springs become stiffer as they are compressed, unlike single-rate springs, which have a fixed spring rate.
This means you'll still retain comfort on the little bumps.
