Going to the 18" compomotives would also be one of if not the most expensive mod one performs to their D4. It's considerable $$ hence the focus.
If the rims where cheap we wouldn't be having this discussion we'd just buy them and move on to the next mod like other makes.
Unfortunately for now we're stuck with one solution. (We don't speak of the other)
A premium rim from a premium manufacture at a premium price.
I'm keen to give the 980's a go, but I know in the end I'll probably end up going to the compomotives.
