The sizes should work, but you may need or want to consider spacers. Most guys run 9.5s with low-30s for offsets in the rear on LCIs. Just as an example, these would give you 21mm less clearance on the strut side than the stock 193m-sport wheels. I'm sure someone will chime in to tell you if that is ok.
Personally I'd only spend money on wheels if they were lighter & or stronger than the stocks (maybe 20-23lbs max for 19s). I don't like adding weight for aesthetics, but its all just personal preference...some guys do 30+lb 20s & others do 16lb 17s. I tend to lean toward the latter, but like many compromise with 18s/19s that are light and strong.
