easiest way to get a lot of clearance is to jack up the front of the car and put it on stands. then jack up the rear and put the back tires on cinder blocks or another set of stands under the rear.
then go back to the front and jack it up higher by putting a block on the jack and using large jack stands like they sell for trucsk under the front.
if you do this right you cna have enough room for kasey to walk under the car......ok.....bad example
