Lets talk spikes and racks

After seeing ER308L's rack. How important is it to spike everything? I am guessing that the most important spikes would be on the floor, is this true? I have this thing https://smile.amazon.com/gp/product/B00004U8A0/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Do yooz think it would be worth it to try replacing the leveling feet with spikes? They are something like 1/4" coarse thread, where do I look for such spikes? Most spike that I have seen cost as much as the shelf, so only cheapos need apply.
Thanks
