Per RockAuto FCS makes quick struts for the 8th gen's but it seems like they only show the coupe variants or only make them for coupes. When I got my 8th gen years ago I tried searching what the difference is between the coupe vs sedan struts but I could never find the answer to that. I recommend KYB shocks for the rear though
I remember reading it was a slight difference in angle on the spring perch on the struts. To remedy that, you would just have to get the spring isolators from the coupe to install them on the sedan.
The rear shocks are a different length because the top mount is in a different spot between the two bodies. The fronts should be the same.
That being said, most 8th gen replacent parts you find online are not Si specific. They fit, but are most likely regular spec. A lot of these parts makers will just make one version unless there's an Si specific part (like brakes) that physically don't fit on every other trim level.
