Very subtle drop in the front. Dinan claims 1/2", I'm seeing a little less than that, but it's only been 250 miles (photo below).
I am very happy with the performance of Stage 1; it was part of the S Package installed by my dealer. The shocks and springs work perfectly together; body roll is reduced and stability is vastly improved. It is also super-tame for daily driving, not harsh at all. Exactly the combo I was looking for.
