Unfortunately fixing [returning to] oem speced Camber with shims [between upper link mount and body] or adjustable upper links or arms, doesn't correct the camber gain curve.
Same problem with toe or caster, lower changes the angles DESIGNED by oem at normal right height.
Those of us with very mild lowering [1" or less] get by somewhat because the vehicle was designed to have a full load of passengers.550 pounds of passengers correctly positioned will lower the body 1" [146 x2 + 123x2 =538 pounds per inch]..........and most passengers weight more than 135 pounds as does the driver.
With Eibach's the extra 15% stiffness [in the first inch] actually help with FAT Americans allowing up to 155 pounds per occupant before that extra inch of lowering occurs.
Japan uses 135 pounds for typical passenger and driver, hopefully you see how weird this is in TODAY's US.
An interesting concept might be to actually lower the 4 mounting bolts to restore the camber angle from shock tower just as one uses shims to restore the toe [inner/outer tie rod] angle. Same with Caster mounting holes by making a new bracket to level the static postion.
