Is the offset the camber/caster measurements?
If it is, I have no clue what the offset is. All I know is when I got an alignment, I told the shop that the car is lowered and they will probably have a hard time getting the measurements to stock specs. After the alignment, they said that they got it as close to stock as possible.
Also, do you think the spring seat on the KYB AGX shocks are slightly lower or thicker??
