I'll add, drop blocks are an easy way to get additional drop. But there are consequences if getting aggressive. Drop blocks beyond 1" in height can put the rear axle scrub-line below the wheel lip if using 15" wheels. In the event of a serious tire failure, the U-bolt ends can make contact w/the road surface. Like dropping an anchor, it's not a big deal if moving unless it catches something or digs in. Wheels w/a larger diameter change the scrub-line dimension offering more wiggle room for a taller block w/o the possible contact concern.

This is just something to be fully aware of when it comes to different lowering methods.

Thank you, So a larger wheel may help as I go lower.

Yes (when using lowering blocks =/>2").

If a 15" tire goes flat but stays on the wheel w/1.5" blocks, it will still roll depending on the thread extended after the nut under the arm that secures the axle tube. It will also likely make some contact & damage the threads @ the end.

Beyond that 1.5", those U-bolt ends are making contact. Larger diameter wheels simply increase the scrub-line dimension allowing use of taller blocks w/o issue.
