Agreed w/both the suspension & tire choice impacting the 'stance'.both have to be taken into consideration lastly when you have your ride height where you want it measure for shocks
If the suspension is stock height, there's not much need of 'measuring for shocks' because spec replacement parts will work. IMHO, the need to measure for shocks comes into play when you start lowering, raising, or altering the suspension pieces/parts.
