12.25 @ 115mph - 100% Stock Non-PP C63
Ive drag raced my SRT8 before but this is the first time at the track with the C63 and first time on street tires. I found these stock Conti's like a decent burnout, RS wasnt worth a darn, and learning to feather the throttle took a few runs - but at the end ran a 12.25 @ 115mph w/ 1.93 60ft.

The first 4 were terrible. Wheel hop, spinning, etc... It took some time to figure out the right combo of air pressure, amount of burn out, and most difficult was the rolling into the throttle (I'm used to 325/45/17 drag radials where you could just mash the gas off the line and dead hook). These 255 Conti's took some "finesse", and the right amount of gradual throttle "roll on" application.
The last 2 runs of the night were the best. 2nd to last was a 12.34, and my very last was a 12.25.
I have a wedding to attend the next day, and I really wanted to stay longer and get a few more passes in as I really thought I could of got a 12.1x pass or better.... but alas, I had to leave at like 9:30.
Next time... was a blast.

I always heard on street tires you just want to clean them off so that's what I was doing for the first 4 runs. As cold as it was, the tires really seamed to like a good cook.
Per a few racing calculators like these:

In the air last night I was putting down around 436hp at the wheels (515hp flywheel 15% drivetrain loss). Not bad for an un-tuned stock C63

I used it about 3 weeks ago and it was "okay", but it was 70 degrees out. Last night, 45 was working against launching, but deff helped once you cleared the line.

The Best of Mercedes & AMG
If I could of managed a 1.7x 60ft, I would of been in the 11.xx easily in last nights DA.
And I can vouch for 11's stock in good air, my best stock runs were at Atco this past March, like you said figuring out how to launch was the trickiest part but 1.8-1.9 60fts are doable on stock rubber.
It totally sux that after my best pass of 12.2 I had to leave. DA kept dropping and I could of probably got in 3 more runs... bah!!
If I did this, would I be the first non-P31, completely stock C63 to get an 11 second pass?
Whats the record?
With drag radials and k&n filters I ran 12.16@115.8.
This is all on pre face lift c63 with 7G trans Tq conv.
With MCT u should be able to get into high 11's stock.
All done at Atco
