Are the lowering springs lighter and/or shorter than the stock springs? My suggestion is to put the struts in without any springs, set it down on the ground, and measure everything. Unless you already did that at the beginning of the project and I missed it. Then take a set of stock springs and cut off 1/4 coil [use a chop saw and do not worry about how they fit in the strut], install, measure, remove, and repeat until you have the 2 inch drop. It may well take four or five tries to get the required drop. NOW send that spring to intrax and have them make a new spring that is that tall but has the ends in the right places to fit the strut. I have only seen coil-overs to replace standard shocks and springs not for struts. Hope this helps, Kenny
