^^ it's not that bad man

I don't know bout tanabe, but w/ my tein's, I just take the tires off an I can raiser lower them w/ my hands if I wanted to, or you can use the tool. it is a pain tho w/ the tool only bein able to do so much at a time.
if you're doin it for car shows, then get air bags/cylinders, but if it's at all for anything else, then I'd stick to coilovers, you can get the height you want and you'll improve the handling as well
