Reverse-eye main leaves will get you two-inches in drop, Posies offers a "low reversed-eye" that will get you another inch. Model T rear spring will result in similar drop. If you want more, you can pull leaves out of the pack, just be sure to not pull a bunch of consecutive leaves as each leaf serves to spread the load. In other words, you want the "span" between the ends of each leaf to be as close as possible.

For example, if you pull the second and third leaf, the distance between the end of the fourth leaf and the spring perch of the main leaf is beyond the design of the spring pack and can put additional stress on the main, since each leaf provides support to the pack. Hope that makes sense.
