back ground info...

05 g35c 6mt
lowered w/ Esplier GT springs w/ Tokico D-spec shocks (fronts 2.5 turns away from firm, rears 1.75 turns away from firm)

after i got my car aligned i had -1.5 camber all around
and yet after like 5k miles i noticed uneven tirewear...

i would understand if my inner tire was wearing more, but its the opposite...

theres more tire(meat) left on the inner side of my rear tires
i'm experiencing more outer tire wearing

any body have had the same problem?
and what do i need to do to fix this problem w/o going back to stock shocks and springs?
