Plywood is good for staying off the ground and not losing nuts or bolts that drop on the ground. Be very careful lifting the car or using jack stands though. I suggest using the largest paver(flat cement square) that you can find. You want a thick paver because thin ones will break easily if too much pressure is forced on them. I would also use a scissor or bottle jack over a floor jack and flat bottom jack stands if you can. Be very careful whatever you end up doing. I had a car almost fall on me because the jack stands had shifted. The jack stands were on plywood and had started to break through the plywood. I was replacing the rear axle on a car and the car started to move. I did the fastest crab shuffle in my life and not a second or two later after getting out, the whole car came falling down. I make a habit of placing a wheel or something solid and big under a vehicle when I'm working on them.
