Well, I don't own a 10 sec
stang, but I have been around a lot of 10 Sec cars.
First off, Consider getting a spare set of rims for track use in 15" diameter if they will fit over your brakes and the world will open up on options for Drag tires. Also, if you have the power to run 10's anythign DOT will have a hard time sticking. Consider soft sidewalls. Even a 16" Rim will have more options.
Also, have you done anythign with your spring and shock rates? Some drag springs and adjustable shicks would help a lot to plant better by assising the weight transfer. Speaking of this, have you done any suspension work at all? There is a lot of ET in that alone.
For your transmission. Once you get going fast enough nobody can shift as fast as a nicely built auto. It is somethign to consider and you will be more consistant run to run. Plus your launches will be more accurate and reliable. Not to say it can;t be done with a manual, just its more difficult.
With power to run 10's I am assuming you have a pretty high revving motor that would require a high stall converter. If you go auto you might want to look into a
trans brake.
