my old mazda was shaking like crazy with 5 inches of blocks (a 4" and a 1"....i didn't do it, was like that when i got it)
so i took out the 1" blocks and left the 4" blocks and the problem was fixed, so i would say you would be safe with a 4" block....but dont hold it against me if you have bad pinion angle problems....
also, i had about an inch of suspension travel with NO bumpstops......so im not sure if leaves were removed or not...
i know up front, i had about an inch of tire-fender clearance with (i think) 195/45-14 tires......so it was pretty low....about 3 inches of ground clearance under the frame i think.......
GOD I MISS MY MAZDA
