[EL PAALO]

215/40 17 up front

rears should be okay with just a roll and negative camber since you aren't past the fenders by much.

Max out camber with the pillowballs (I assume the megans have pillowball uppers?) for clearance and then get back to something reasonable with crash bolts (toyota bolts slip so I'd get something eccentric - I think ingalls (sp?) makes some) while still maintaining most of the clearance the strut tops gave you.
