McCall, with the double adjustable QA1 coil over spring and shock package I have, like pictured on page 2 of this thread, there is ride height adjustability from 0-3" inches depending on the spring rate you choose.
I went with 450 lbs/in and I can adjust my ride height from 0-2" inches in the front.
For a strictly street driven machine, I would recommend the 550 lbs/in which would allow ride height adjustments of appx 0-3" inches.
I also have a set of 350 lbs/in springs which only give an adjustment of 0-1.5" inches. The 350 springs are a little light for our Montes but were purchased for drag racing.
This is the easiest setup I know of for multiple ride height adjustability. - Dave
