i have american racing outlaw 2s that are pretty deep dish
in that case, you are probably going to rub the firewall
you can probably find an ifs lift pretty cheap used
you can also do a body lift ( i recommend
www.4crawler.com )
sway-a-way or downey upgraded torsion bars
www.sdori.com balljoint spacers
you can do a good amount of lift pretty cheap if you want to
also, if you trim the firewall, or tub it, you will be able to fit a larger tire than stock easier....
going from stock gearing to 33s is going to suck though
