06 470. 200k miles. Air bags bad. So replace. The 470 is stock. It mainly gets used to take the parents to doctors appointments. Seat height. Went with Metal Tech rear delete with springs. Bilstein shocks. Trying to keep approx stock height. Back is raised about 2" from the middle height of the bags. Getting ready to do the front. I would like to raise the front about 1". What notch would you use on the Bilstein 5100 struts to get that?
