Well, I own an EVO, but from what i've read in forums... there are many evos that have run 12.9-- with perfect conditions. It is possible from what I've read, I have yet to see it. Most that I have read are along the lines of 13.1-5.
Though I wouldn't use the C&D reviews...they are kinda slow. Thier first review of the EVO had the car running a 14.4 quarter mile.
On the note of the first paragraph, replace just about everything that says EVO with STi and that's basically what I have heard about STis myself.
