Im planning on doing the same on my 06 E.G. Progressive kit. I have a 21 up front and wanna get the bike as low as possible. Im short as well. Im already having issues with the rear. Im running a matching 18 out back. streetglide 12" shocks. tried the lowering blocks and no bueno. Trashed a rear tire. had 25 pounds in the rear. Have an Arnott air ride set up coming. My concern for the front is that I dont want it to sit lower than the front when I install the lowering kit.
