In Reply to my Exedy Hyper Stage 4 - Twin Disc Clutch Kit - Brand New/not used - $1250 that I have posted for sale
I don't see why it would work for your 2011WRX, looking around the internet looks like it works for all EJ257 motors. (2.5L 2458CC H4 GAS DOHC Turbocharged).
It's still available, Shipped to Seattle would be minimal since I'm in Portland, OR. like around $30 3-5 day shipping.
Let me know soon since I've got others looking at it too.
I can easily send you a paypal invoice.
Just need your email address.
feel free to contact me as well,
