Shouldn't I be in the 12's with my mods???

Your times will vary depending on temperature, tire grip, and the track itself. Normally i'd include elevation there, but altitude is doesn't really affect a turbo motor since they make their own atmosphere inside the motor. What kind of tires are you using? Did you lower psi? From what you posted up on the post it seems like your biggest improvement would come from your launch and 60 ft times.

DRs should drop you to the 12s, but there's something else up with your car.

Only trapping 108 is well under what a down pipe and jb4 n55 should be running. I'd expect you 111-113 at least. Unless was it one of those really hot days, high elevation (can't imagine you could find that in stl?

Continental ContiSportContact 3 @ 30psi, pretty worn out. I'm definitely having trouble figuring out how to launch the car with the DCT.

Should I be short shifting 1st gear to get into 2nd faster?

Temperatures for all those runs, because they were done on a few different nights, were between 40 and 70 degrees. Elevation is pretty low I would imagine, the track is right next to the Mississippi River.

I would like to get a set of 17's with DR's in the near future.

Also, important to note that the meth was not installed during these runs.

So upgrades are:
- 4" DP
- BMW exhaust and midpipe
- Charge pipe
- FMIC
- JB4 Stage 2, Map 2, standard settings
- Ran the Injen intake, recently uninstalled and installed stock intake for last two runs
- Lighter trunk, hood, battery
- Lighter wheels than stock
- KW V2's, damping setting on full-hard front and rear
- Stock RFT's in front, 245/35, 50 psi, fairly new
- Continental ContiSportContact 3 in rear, 255/35, 30 psi, pretty worn

Lower your psi to around 25psi for more grip in the rear....and that weather was cold. Summer sport tires don't really like temps below 45 degrees as their grip will fall off hard. Launching the DCT isn't easy b/c with upgrades it's too high and will cause wheel spin. Also you want to soften the rear shocks. You want some weight to transfer back there and help push those wheels down. Try leaving the shocks in the back about 1/2 way.
