Yes its probably not great quality but there's loads of it to account for that.
so very true, i fink teh amount of material i removed compared to teh amount of material there already is there iwll deffinitly be a difference in strength but its a very smalll amount
usually standard cheaper cast wheels bend on the inner banding where there isnt any spokes, so id probably say there weaker but no where near as weak as the inner banding so shud be ok
