Default 12.20's in a bolt on m6 car!

went to the track tonight. the da was low 500's. i lowered the psi down to 13 this visit, put the rear on 7 and fronts on 3, and hooked up the 2 step. first couple runs i had the 2 step at 5500 and clicked off a 12.40@109.43 and then a 12.352. raised the 2 step to 6000 and put the fronts on 1. the times went way down each run. i would hot lap the car 3 runs then let it sit for 20ish minutes. clicked off 3 more 12.30 passes then 4 consecutive 12.2x passes.
thanks goes out to butler for giving me some pointers and lining me up in the best groove possible

best pass:
r/t .187
60' 1.687
330 5.002
1/8 7.788
1000 10.209
1/4 12.251
mph 110.22

there was only 7 cars and a bike running at kcir. some spectator in the stands swore i had a bottle after he looked at my car and i told him it was a stock headed, cam, intake, bottom end lt1

thanks to everyone that helped me out my goal was 12.40's in this car and i surpassed it

car is the 96 formula thats on the right in my sig
my setup:
raceweight 3200
-qa1's all the way around (cut v6 springs out back)
-bmr extreme tq arm (with ds loop) and sfc's
-acpt carbon fiber driveshaft
-umi chromoly double adj lca' and panhard
-spohn 1" rear sway
-narrowed moser 9in (mini spool w/ 4:10's)
-26x11.50 et street (bias) w/ draglites all the way around
-bolt on's and all free mods (no emissions at all )
-ewp, 1.6rr's, manley springs
-msd 6al, 2 step, and coil
- true duals with delta 3.5in flowmasters
-t56 swap with a lt4 clutch

its pretty much a stock motor car with rr's and better springs

things i still need to install before the ltx shootout:
-grant aftermarket steering wheel
-pa racing chromoly k member
-msd cap and rotor
-battery relo kit
-holley 52mm throttle body


i should have some vids up soon that a buddy got when i ran it at kcir
