How low can I go with inner fenders?

[MONTEZ]

I want to know the best way to get as low as possible when aired out while still running the factory fender wells up front. I am still gathering up pieces for my suspension and need advice on what to get next. So far for the front I have Upper an lower strong arms and d2600 bags. I am planning to get a set of McGaughy's 3" drop spindles next. As for the rear, I am currently undecided on what I want yet. I just want to get my stance in front figured out first and move to the back next. I am not opposed to running 18" wheels with smaller tires it it will work out better than running 20" wheels. I have no plans for 22's. I have a pic of a truck I found on the forum, which is maybe a little lower than I can get, but I doubt he has any inner fenders. Can anybody help me with a combination?
