Stock height adjustable coilovers?

Are there such things as this? Adjustable coilovers that go from stock height to a 3 inch drop?I would love to find some because whenever my family comes in I pack my car full of suitcases and people(large asian family:D thats why we bought the max:) ) so when they all get in I notice my wheels almost tuck into the wheelwell. Ever time I consider lowering my car i think about how many peopel sit in my car during the holidays and how many shopping mall speed bumps I need to pass:(


.....ouch, ironicly the Integra across the street just scraped while backing out of his driveway:p

Thanks in advance
