Air ride setup under the flooring sir. Level of ease to access is subjective; some people may not mind removing the floor, others may find that to be way too much work. I think it's fairly easy to remove, but a little tedious to get it to line back up perfect when installing. You could glue them all together with a backing and make it a looser fit and then it will come out super easy, but since this is a show car it needed to be seamless. You can't be fashionable and comfortable at the same time ;)
