I was told never use air bags with trick springs. Trick springs come with different spring rates. The passenger side spring is stiffer and shorter to compinsate for the hit on launch. {Car should leave level}. I just put Moroso springs in my wagon with Qa1 shocks. Haven't run the car yet but will see in the Spring!Malibu355 said:

But how hard are you launching and what spring are you running now..???
There is a difference in running a 13.0 car to a low 11.-10's..

i was told something similar about using bags with trick springs. the only reason i wanted to run them is to control how much it squats down as i don't have much tire clearance.
I ran mine at 12-15 lbs. in the passenger side with a 1.58 60 ft. My car pulls the left front about 4-6 inches and it was twisting pretty bad before the bag and the torque rod to keep the motor from beating on the stock motor mounts...
I've had the best results with 18-20 in the pass. side bag. 1.57-1.62 60 feets leaving at 1400 off the footbrake with a th350. The trick springs are already "compensated for" so should not need bags.
Dont know if it will really drop your 60 ft much... It might make you a bit more consistent and make the car a bit more predictable to launch. If you aren't running solid motor mounts a turnbuckle would be a good addition... If you want to drop your 60 ft. you could flash the converter from idle instead of loading it. Prob. a little harder on equipment but I pull in to my staging lights and clean up the idle to just about 1000 or 1100 (that way I use all my acc. pump shot on launch itself) and hit the converter just as the third yellow hits. Its hell trying to take up 2000+ rpms and be clean on the tree, gotta work on that next season once I quit changing the car up chasing a low 7 pass...
lol thats funny cuz i have been chasing a 7.5xx pass all year and finally got some. also has a few run ins with broken parts but it happens. im trying to run 7.50 index class this year and some summit brackets.
I believe that you're ready for a bag and some stiffer arms. The flimsy arms and mushy old bushings are not helping ya' at this level. You could also start to research altering the IC geometry. I would bet that with some suspension work you'd get your 60' around 1.50-1.55. That would knock 2-5 tenths off the et. Do one at a time (starting with the bag) to get to the 7.5 index you're after.
someone pmed me a IC diagram, but I seem to have deleted or buried it... Anyone got one to pm me??
