I have '99M3/2 with NO engine mods (only some brake mods). I am running S-02 (with 6 track days and 12000 miles on them). The temp was about 74 degrees. For those in the bay area, I was on that strip of Mary ave in Sunnyvale, just North of Maude (very empty and wide).

As you can see, I went in both directions on the same road (N->S, S->N). I tried launching with little to no wheelspin (2500RPM), and seemed to get consistently slower results. The 3000RPM launch's had some wheelspin for about 1 second. I did a few practice runs before the recorded ones, and I was consistently get in the 5.3's w/wheelspin.

FYI...
