They're statically balanced, but when it's spinning at over 200,000rpm, dynamic balancing IS important, you have to balance the assembly as a whole...
You can't balance an assembly as a whole with only one part... Especially with the tolerances required at over 200,000rpm...
Hence yes, replacing wheels is all nice, but unless you VSR it, it's likely to end up with your engine eating a compressor... Especially since GTs run seriously small shafts to reduce inertia...
I think that pretty much sums it up, its a ball deep situation unless you're VSR ing the complete assembly!
