Hey, I see all those slammed cars with hydraulics to get them up to "driving height", but do they do this to lift vehicles? I would like to drive in town at the normal height but when I could use the xtra 4" I'd like to be able to press a button and bam! 4 extra inches. Is this possible? for a somewhat limited budget? Can the system be submegible? I'm just dreaming so let me know what you guys think. Maybe even an adjustable lift, now that would be cool!
