lowering frontier, lower this time!! need help!!

well i had my frontier lowered last summer w/ cranked torsions and 3 inch blocks. This isnt enough and it rides like shit from the torsion bars. I am gonna go w/ 2inch drop spindles in the front w/ torsions cranked a lil bit. What can i do about the back to go lower than 3 inched w/ the blocks??
