If you are looking at an ST as your user name suggests, it's worth it to get a 23. A good deal of 21-22s have inferior rear subframes. To me, getting a 23 with the correct one like the 2020's is worth $1000 to me. Then again, you may be kicking yourself if 24 brings in the midcycle refresh and 23s get slashed towards the end of the year.
