How can I put this?

With stock springs you want to keep it at the higher setting do to the spring rates.

Why? mainly for damping reasons, what using the lower notch does is shortens the shocks compression stroke, which means that if you had a higher rate spring, (a lowering spring) the spring would be more agressive at managing load, or not as eager to compress as the stock spring would meaning the shock would do less compression, and more rebound which is where the adjustable part of the shock effects.

So the point? The stock springs will still compress, the same, only now that your shock body is moved up, it will have an 1-1.5" less room for compression stroke which means your shock will be spending more time in compression which makes the rebounding part work harder, which is not what you want.

Can this be measured? Will you notice a difference? Probably not, you want a lowered look? Get sport springs, don't let the dampers make up for weakened load bearing, that is the springs job.
