Suspension suggestions??

OK...The engine build is underway. The heads and intake are off being ported and polished, along with 2.0"-1.56" Manley valves, and CC double springs.
The cam going in is a CC 305 with CC 1.6 "Pro Magnums"
Other mods are a 58MM throttlebody, 30# injectors, AFR "hydra-rev", MAC headers, Aeromotive AFPR, Fluidampr, CSI water pump, and a few other little things plus a 150 HP NX kit with progressive controller.
The car went 12.82 last year with a bone stock engine with exhaust manifolds, and stock suspension, on M/T 26"x10.5" M/T ET Streets.
I've stepped up to 26"x11.5" ET Streets this year, but the rest of the suspension is still stock. What are the first logical things to modify to harness the new power? Are adjustable lower control arm really needed? Are HAL's really needed? Torque arm? Air bag?
I'd appreciate all input, especially if you're in the low 11's/high 10's.

frank,
from what i've been reading-
HAL Q1 shocks are the way to go with some slicks
LCA, SFC and airbag help a ton. Pretty general statement, but thats just what i've read here.

I agree...Hal's are sweet ( i got them all around) and i have SFC and LCA. i say get some re-location brackets as well

I woudl definitly get the QA1's, adjustable LCA's, and relocation brackets. BMR seems to be the way to go. A torque arm will help out but you will have a greater chance of snapping your rear end. I would suggest getting a 12 bolt(Strange). I would get some BMR weld-in SFC's to help with the chassis flex.

Maybe I should have mentioned earlier that the car is getting a 6 pt. cage, so the SFC aren't neccessary...Especially since this is also a hard top car.
The reason I specifically asked about the QA1's is because I've seen some people that have installed them and not 60 fted any better. I've also seen people install relocation brackets and LOSE traction!
Does anyone have back to back 60 ft. times proving the stuff their installing actually works? If so, how much did your 60 ft. drop from the modification/addition?

Hey Cheese? You have any track time on your set up? (Hal's) I will someday set up my suspension for the strip & get rid of the stock stuff. Just wondering what your expierience's have provided in effort for my plans....
