if i remember correctly, you have the toyota CV shafts in, along with the hagen front end widening. but i cant remember if you are actually using the stock vitara diff housing and centre, or if you changed to the toyota housing.
OME struts are 30mm longer in shaft stroke to stock vitara struts. on a normal vitara, a mount flip and the OME is as much as you can go before you start killing the CV joints. but with your front end mods, the toyota shafts should be able to handle the added movement, and the added angle. if not, then lower the front diff housing some more, and that should give you a bit of room to play with.
a OME strut, and maybe a 2"/50mm strut spacer will give plenty of droop, about 3" over stock, but because of the front end widening, and the increased leverage on the arm and coil, you may bottom the strut out on full compression.
maybe get some OME struts 1st, and then expreiment with them, and also, your front coils may be too stiff/soft for the front end mods. maybe look at getting some custom front coils made up.
