Actually very few people, or none, have pointed to a stock wrx post 2008 with failed ring lands. Andecdotes , which is all we have, to me suggest that STI fails much more often in stock form than the wrx. Are the AFR so bad on stock wrx vs known lean on STI? It would be interesting to hear from stock wrx failures. since presumably , at least post 2009, many more wrxs are sold vs STIs one should "hear" about more wrx ringland failures, but i've noticed the failed ringland threads seemingly always entail an STI sometimes in stock form. I'm thinking of ordering a '13 and for this reason (well, speculation) I'm leaning towards wrx.
