M/T ET STREETS At The Track!!!!!

I Just bought a set of 275/40/17 Mickey Thompson Et Street Radials. I am goin to the track this week end with them to see what i can run. Here is the run down of my car.
1996 SS
383 Stroker putting down close to 450 to the wheels N/A
6 Speed with Street Twin Clutch
Stock Rear and front suspension.
Strange 12 Bolt w 4:10's
Cam range is 2500 to 6500
Zr1 rims on all four. 17"/9"

What should i do to get the best time out of my car???
1. What should it launch at???
2.Should i take the front sway bar off???
3.What PSI should i run them at??
4.How long should i do a burn out?? ( Bleach box????) (I have Line Lock so i can hold it all day!!)

Or anything else i should look at.

THANKS FOR THE HELP!!!!

Goodluck! Front sway bar is dead weight. Do you want dead weight? No experience with that exact tire, sorry. I'd shoot for 4000rpm clutch dump and see how it feels. It might want more but It's trial and error@!

take the sway bar off.... more body flex in the front and less weight.

tire pressure/launching you have to play with. general rule of thumb that I use is use the most psi in the tire without spinning. reason behind this: generally the less psi you have in your tires, the less mph you are going to trap, but you are going to hook better. more air in your tire = less traction but more mph. I use that rule of thumb with slicks b/c they grow the faster you go. I believe it should still apply to radials

and a good burnout. hold it for about 4 or 5 seconds on the first pass.

psi/rpm to launch: start at around 16 psi and work your way down/up. don't just dump the clutch either. that's a lot of drivetrain shock and will hurt your 60' time.
