Totally resurrecting this!
Has anyone found and answer to the "TCS off button = open front and rear diffs on 08+ WRX" question? I tried to get Cobb to let me put mien up on the dyno with 2 wheels jacked up to test it... they weren't having it lol.
Also would be intrested to hear about anyone else with LSDs on the 08+. What they used/impressions. Would be nice to find a good replacement for the center diff as well.
