60g per wheel saved with double butted spokes and because they are stronger, the number could be reduced (unlikely as the front hub is custom)
If you order a 1000 or so tires and rims, manufacturers will build the model you want, rather than being limited to "stock" models. And seeing as 507 is a rare size, Helixs production numbers may be sufficient for their own spec now.
All totaled, a pound (450g) can be shed on the rotating weight alone. And we all know how important that weight is.
