Hi Dan,
Well as Dopogue, mentions those spikes are no longer available. Also my stands are different than the stands you see on the Stein Audio website. They are of my own design, that I asked Scott to produce for me. My stands are larger than the stands on the website. They are 1.5" taller and 4" wider and deeper, so even without the outboard spikes the footprint will be wider still. My design can be seen here...

I also contacted another member here who made his own outriggers, and I may make some similar to those. We'll see.
