i very much doubt you will be able to move the hub out 5 inch without mods to top mount position , just cut the top off and plate it with adjustable top mounts that way you can also set it up for road or track etc.
it all depends on budget etc but you could use mk motorsports wrc stuff front and rear as most of the equipment is fully adjustable , or you could use the cheaper adjustable tca from comp brake etc .

if you can weld you could built your own set up with laser cut parts etc
