Yes Studio 27 do do a decal sheet for the 2002 Subie. However it isn't that good since the yellow graphics are printed as plain yellow not fluro.
Much better in that regard is the AMS set but Rainbow 10 are all out of them at the moment (just checked).
I've got both the above decal sheets and will someday get around to using the best of both to build Tommi's Monte 2002 winner.
Just checked and MediaMix have one of the S27 sheet in stock, follow this link
