There were aluminum "bushings" being sold for the WRX to be pressed in place of the rubber bushings.
There were threads back in '02-04 about people installing these and it was difficult....
It is also possible that an early '04 Sti may still have rubber bushings and only an '05+ Sti is guaranteed to have metal spacers.
From what I recall from those early threads, they do make a difference, just like subframe lock bolts do.

So, when you say rubber bushings are you referring to the outrigger bushings or something else?
If it is the outrigger bushings, then it would be easier to simply replace them with the TiC race outrigger bushings, which are almost a solid bushing, Shore95A on a scale of Shore100A, and/or add the subframe locks.
I'm just looking at it from a workload/financial viewpoint.
