You could use those if you wanted the bolts to be visable (on the face of the wheel). Standard OEM bolts will be burired deep in the wheel, but work fine (Ronal R9's).

I was told the Ronals had a cone shank which would me they would not work with the stock bundt lugs?

I bought cone shanked bolts and they seem to be working good. Are some ronals ball shank?
