I've been tracking my 0-60 times with the AP since I had my 2011 WRX. I just got the transmission rebuilt, replacing a broken interlock arm, adding new synchros to 2 and 3, and also replacing 2nd gear. Man is this transmission WAY better now.
I always had problems getting into 3rd at high RPM (drag launches), the previous owner(s) had definitely left their mark on the trans. Now that its back, it's a piece of cake to shift it.
Pulled my best 0-60 (based on the AP) with the new rebuild, I think there's a 10s run in her
