Before I set my eyes on the Enkei Raijins 18x9.5, I have (I haven't changed since the raijins are giving me a hard time) the spacers that perrin sells.

These are similar to the Ichiba V2, and are thick enough the OEM studs are fully inside the spacer. so any wheel will fit without issues.
If you want to stay with the stock wheels, check them out. they have pics of the OEM wheels with 25 mm spacers and the fitment looks great.
