If the car looks correct in the rear then I would lower the front with the thinner pads.
Rule of thumb on ride height; if the alignment checks( ft & rear camber) out & the rocker panel molding is level(measure to level surface) then you don't have a problem.
Again at dealer we have angle gauges for the control arm angle & this is how we check for ride height PROBLEMS.
