Hey All, first time posting to this site.
I too installed the Curt Hitch #11286 on my 2012 Impreza Sport Limited. However, I didn't use the supplied hardware so no drilling is necessary as we fabricated a larger carriage plate to better distribute downward forces. Also, modified the hitch to have a 2" Receiver
Please note... I do not intend on towing anything. I only did this modification to so I can use my old bike rack which requires a 2" receiver.
>Curt Hitch #11286 $150 shipped
>Curt Receiver $30 (don't have a part number, but here's the part on etrailer.com -> http://www.etrailer.com/Hitch-Access...Curt/E-11.html
). I had purchased the 12" length, but the 6" length will work and is cheaper.
Additional info. Curt was cool enough to create a page on their site regarding a question I had about their hitch. http://www.etrailer.com/question-39798.html?fb=yes

This approach requires the removal of the rear bumper and bumper reinforcement thingy (not sure what it's called).
Fitment test with the original Curt hardware. The 12" receiver shown for size comparison.

Used a band saw to cut the Curt hitch and TIG welded on a Curt 2" receiver
When all was said and done, we sprayed on primer and painted the sucker gloss back. Initial load test shows that the hitch is fairly stiff. We noticed more flex in the bike rack than the hitch itself.
