It just like the Lambo doors, first you open them a little bit like normal doors then you push them up. If you look on Ebay there is a guy selling instructions on how to do it yourself, but i wouldnt do it. He says you need a hydrolic shocker, screws, hedges and a welder. If you would to do it yourself, best is to try on a shitty car or something cause you wouldnt want to stuff it up... Specially if you welded the wrong spot.
I know a place in Melbourne that fits them i think, try www.racingproject.com or something, cant remember.....Iv emailed them but they havent gottin back to me.... Ill let you no.
