Oops, I quoted the spec for my STI, not your WRX. But the that doesn't change anything in my answer. The +55 is the most significant number.

Actually a 9.5 inch wheel with the same offset as a 9 inch pokes out 6 mm farther. So actually the 9.5 +38 pokes out 3mm more than the 9 +35. It is the tire that will rub. The shape of the tire on a 9 vs 9.5 could vary by more than the 3mm.

Both your choices are very close in all aspects, both performance and fit. They are both at the limit of what will fit without rubbing. It may come down to actual tire chosen to determine if it rubs.
