I have all BMR suspension so I would like to keep a constant.
Right now I have the stock rear sway bar and I know it is hurting my performance. My driver side front is like 4-5" off the ground and the passenger is like 1-2". The car also jerks a little to the right, right at the initial hit of the tires.
The only problem is, I heard all the drag bars like the BMR are really bad on the street and this car is driven on the street.
What do you think?

These drag bars do stiffen up the rear and if you run one of these it is a trade off, street vs. track.
We put a THICK sway bar on a another buddy's car and it helped his car out but it still uses stock end links. you could try that, get like the biggest rear sway bar you can find that uses stock end links. his car was squating and rolling over bad, now it still squats (function of the shocks) and it does not roll over nearly as much on the launch.

Shon, I'm suprised nobody else mentioned this. Loose the sway bar, LCAs, air bag, etc. Call Pete-Z and do what he tells you. Put his bars on, and fix the front of the torque arm like he says, it will leave straight and level. Look under the fast NHRA stock F bodys, you won't find any of the stuff under them. You will find Pete-Z bars. I did put a 6 cyl coil in my left rear to help it going to the right some when it is up a long way out there. (Like making the 1-2 shift in the air) With PeteZ's deal, if it pulls one way just shorten the upper link on the side to pulls toward. Seldom takes more than 1/2 turn, if any. Set them like he tells you, and you probably won't have to touch them again. Mine goes 1.31 to 1.35, on 9" tires, depending on weather. In good weather, it has gone low 1.30s breaking the 60' beam on the rear tires.
Good luck, Ed
PS: I think Madman maybe makes a similar set up. Probably at least as good. I would ask him.

I am a bit "skidish" of the Pete Z's b/c when they first come out no one was having luck with them. I am sure that now that they are being used by more folks and more support is there for them they might work well on some cars.
I am not messing with my current suspension set up, other than maybe some adj shocks for tracks that might not be sticky.
Pulling 1.59s with a bolt on LT1 is pretty good if you ask me. There is no way putting any other suspension style on this car will help the 60's at my measily power level.
Now we add more power or change the trans ratios it might help the 60's.....or even less weight...

I was going to have Neverlift Racecraft install an Anti-Roll bar but it was expensive and I am sure it will be very bad on the street.
I am not sure what the Pete-Z set up is, that Ed talking about above?
After doing a search on rear Sway Bars I am only more confused.
I don't have scales or any of that stuff.
So if I were to preload my stock sway bar (just to get by for now)
I would have to shorten the link on the passenger side?
Thanks

We did not put mine on scales to preload the bar. Actually we followed Spohn's directions that were sent with the bar and it was perfect, I did not have to make any adjustments...
PM and I will see what else I can do for you.
