Ok, got a 03 GT vert and one of the first mods I want to do is the subframes. What type do you all recommend and what kind of shop do you recommend put them on? (auto repair, body, muffler?) Can I buy them from AM and have the shop put them on? I heard you want to have them use a lift that you drive up on and not a 4 corner frame lift. This makes sense, is it recommended? Thanks in advance guys.
