I have the longer damper rods in the forks, and when I had the springs out (and no oil) I found I could push the wheel up till the lower fork parts would hit the lower triple tree or close to it. So I made the top of the tubes (caps) about flush with the clamps, they had been up an inch at least. The new springs allow more travel and more sag and I did not want things to hit. With oil I think the hydrolock bump stop comes into play. With the progressive springs the forks would sag about 3/4 and inch to an inch with me on the bike, but the travel never went past about 4 inches. With the TW springs, static sag is an inch, sitting on the bike is another inch roughly, and travel from there is about 5 inches (so far). So the bike sits at about the same height but I have more and softer travel. The progressive springs really seemed too stiff to use much of the travel even under hard braking and big bumps. I have big speed bumps in my area and the forks now absorb them much better, I can fly over them and the forks just soak them up. I still have a lot of ground clearance and have not come close to grounding anything and I have run to the edge of the tread on the tires (no chicken strips).
