The guy probably didn't heat them up enough. One of our local guys (Mark) has pulled 1.7s on nittos with a M6. I pulled a 1.6 last time out on stock RSAs but my converter has alot to do with that. Was his car an A4 or M6? I ended up running a 12.222 @ 111.48 with only the mods listed below with the spare and jack removed. No suspension mods or anything else. I'm bolting on some ET streets tomorrow to try and squeek into the 11s.
