I have an 05 Sti (actually for sale). My car with a tune full exhaust, external wastegate, and a frontmount(with stock turbo so prolly hurt me), and intake went 12.6 at 111.9. Mostly stock on the street vs a good driver i dont think you have a chance....at the strip if he can drive once again not a good chance. Ive got an 01 Z06, Ive had a 98 SS, my girl has a 06 GXP, and i have an 05 STi so im not prejudice either. Just facts, theyre amazing cars really. Bone stock runs 13.2, you get 25+mpg highway, and can drive it literally anywhere you want through snow over the hood. But to each his own.
