we put a 3 inch in our grand vitara, with no diff drop brakets, and as i did with our trackers when they where still ifs, i used a smaller top bolt to get the camber back, i just tried different sizes till i found one that worked....

ps: dont go calmini, it will ride like a 1940's jeep
oh ya, and a 2inch will net almost 3 inches of lift on the gv's and vitaras, in the front anyway
