So I’m out looking at used WRX’s. Thinking 2017-2018 because of price. I’ve driven both and was curious about something. The clutch in the 2017 is much stiffer than the clutch in the 2018. Is this the way it supposed to be or has the clutch been replaced? It almost feels like one is cable and one is hydraulic. Did they change the system from 17-18?
