My input here is this... I've watched enough crashes to see that alot of cars would benefit from anti roll bars. It seems the first thing guys do when setting up thier cars is remove the front sway bar. This is probably the worst thing you could do to a car that is traveling at the speeds we see. The problem gets compounded when you throw a ladder bar into the mix. A car with a ladder bar and no front bar usually will hit the wall. Stiffening the back without doing the same to the front may be fine when the car is in a straight line, but it can and does turn into meyhem when the car gets loose at speed. My advice is if you are adding a rear sway device, do the same to the front. This applies to "stock" front suspensions, not low/ strut cars. As far as what rear bars do for launch, I added one after a few years of going without on a 4 link. It calmed the car down on the launch to a much more manageable line down the track, although my best 60 ft was without the bar (1.28 vs 1.29 with) The car drove down the track like a caddilac. I wouldn't build a stockish door car without one

I will never run a four link again without one. Our car can be a real handful without it, and with it, just night and day difference.
We had some trouble setting up the four link. We finally got that set-up better, but still had some pretty good roll to the passenger side. It would roll to the passenger side on launch and then the other way on decel to the point your correcting with the steering wheel.
When we put the S&W bar on it, we rescaled the car, set the coil overs level, and adjusted the preload on the sway bar...Car leaves level, and goes thru the traps level. For me, its about safety. We had some aborted runs when the track was marginal, and since doing this, it seems like the car is easier to drive and handle.
I see even the dragsters steer to the right on the launch and have to correct all the way down the track...Do I have to have it to get down the track, No, but I will not do another without it.

I don't use a ARB. It leaves dead level. The car handles well at speed. Stock rear frame rails with ladder bar. 1.32-1.34 60 ft. Best of 9.25@147 on 10.5's@3340. Doug

With my car it seemed to be the length of the ladderbar, combined with where the front mount was on the neutral line. When in the bottom hole, the ladderbar straddled the neutral line and the body roll was severe. If I moved it up away from the neutral line it calmed down.
A short instant center that straddles the neutral line must allow the left side to rise above it and gain leverage upward due to torque roll from the motor which then forces the right side down below the neutral line, and the forces feed on each other to cause severe body roll. That seems to me why some have very little need, (high torque, two speed, long instant center above the neutral line) while others don't.
I am betting that the gains seen would be related to preload needed without the anti roll, and how much of the available traction a car needs. I can see where a smallblock car with a glide and big tires would not see anything at all in a lot of cases. A nose heavy, bigblock three speed car on the other hand may gain a lot.

Have so much trouble hooking up on marginal track (Irwindale) with radial slicks I don't even bother going there any more.
LOT'S of body roll, but the car drives straight and true when it hooks.
My car leaves like that too, and I have a bunch of preload in the upper right bar. Goes straight down the track though. I'm going to put one on mine too.
Suggestions for whose bar is better are welcome.

You should see some gains on your car with an anti roll, especially with radial slicks that are being over powered as it is. I had to go to less air to get some hook, and lost the 60 foot after about 25 passes. It went away by .06 to .07 almost instantly. I suspect I should have tried switching the tires side to side, but switched to a bias for safety reasons.

Note on mine we used oil lite bronze for bushings & drilled tapped for a grease zerk fittings to keep it lubed. It will bind with time if not lubed. This saves from having to take it all back apart to do so each time.
