Caution for jacking up a lowered z using ramps

azn370z

When I Jack up my z I drive onto two 4*8 so I can fit my low profile floor Jack under the z. I usually leave the 4*8 under the front tires unless I remove the wheels. I put the wheels back on and lowered my z back down without placing the 4*8 under the tires. I usually slowly lower the z back down but this time the handle was stuck and as I twisted the handle to lower the z, it came down quickly. The handle completely bent the sport lip back and the floor Jack was stuck under the car. The first thing that came to my mind is the oil pan is crushed and the second was good thing my varis lip isn't on yet because it would of been broken.
