Body roll part 2....see!!!
 

Ok lets hear it....Will anti roll bar fix it? Mine is the Camaro someone was nice enough to send me the pics.. Car only has 4 point cage, I am welding in the door bars and re-enforcing the frame connectors this week, will that help?

Still got leaf springs?

Re: Body roll part 2....see!!!
 

Yup has Afco multi leafs on it, bout 2 seasons old..

Re: Body roll part 2....see!!!
 

Check your centering pins

Re: Body roll part 2....see!!!
 

Or the location of the new spring mounts. ..Better string line the rear before doing anything else. ..........Tom

Re: Body roll part 2....see!!!
 

You better build your own sway bar and build it super strong. Most antiroll kits are designed for cars that dont cork over that hard. I have a stock suspention malibu that used to leave on the passenger door handle. I looked at buying one but they were way too lightweight. I built my own and built it bomb proof and I still tweeked it. You car looks good with the mini tub and it would be nice to fix the problem but would it be possible to put the shocks back into the stock location and try it?

Re: Body roll part 2....see!!!
 

Chicks dig twisted wheelies. How about adding another leaf on the right side?

Re: Body roll part 2....see!!!
 

I checked the pins on the rear, they are good, also string checked it that is good. We put the shock back as close to the stock location as possible and angled the tops in a touch, it didn't help at all. I have installed the door bars as of last night hopefully that will help a bit and I will just throw an anti roll at it, I would love to see some specs and materials of one that you made for yours. Thanks for all your input.

Re: Body roll part 2....see!!!
 

Looks a lot like some serious frame and roll cage stiffness problems to me.

Re: Body roll part 2....see!!!
 

the car did only have a 4 point cage in it, I have this week welded in the door bars, the car does have frame connectors on it and I are in the process of beefing them up as well. Keep in mind the car was minit tubbed and the leafs were moved in about 5 inches on each side and the shocks were moved in about 3 inches on each side. I just want it to go straight again.

Re: Body roll part 2....see!!!
 

Ok so I took it back to the track this past weekend and as I stated I welded the door bars in and also welded the sub frame connectors solid, I also tightened the front shock adjustment and it helped quite a bit but still twists, I was wondering before I put the anti roll bar in it what you guys would think about adding another shock to the back of the car on one side. if you notice in the pictures I have 2 different mounting locations for shocks on each side, my question is if I do try this which side should I put it on. I guess I have thought about it so much I have confused myself, would I put it on the drivers side rear to try to slow down the body seperation on the drivers side or would I want to put it on the passenger side to help control the compression on that side? Some folks watched it and said its like it does nothing on the passenger side rear and its all in the drivers side rear. I have thought about it both ways and I guess it makes sense both ways, just wanting your advise as I will be trying it out one way or the other this weekend. Thanks in advance...Oh just to clarify I am saying i will be running a total of 3 rear shocks 2 on one side and one on the other

Re: Body roll part 2....see!!!
 

No. Have you pulled your rear shocks in and checked the valving? My car used to twist with QA1 single adjustables...Turns out 1 was bad. I now have AFCO double adjustables and the twist is gone.

Re: Body roll part 2....see!!!
 

Like Small Bock said, the shocks could be your cause. Did you change shocks from side to side and see if the car reacts differently. I am sure you have done this but have you extended the shocks and see if they stop short? I am taking a wild guess now. I have seen some nice roll bars from RJ race cars and even Competition eng. Good luck.

Re: Body roll part 2....see!!!
 

I have pulled both rear shocks and both feel exactly the same. i was just curious to see which side you would put the extra shock on. I have tried everything but puttin an anti roll on it, had some extra shocks so thought I would try it, just didnt know whether to try limiting the seperation on the drivers side or compression on the passenger side.

Re: Body roll part 2....see!!!
 

Eric, think of it this way. When you are under throttle, the rear axle is acting like a big propeller. Instead of the drive shaft and pinion gear turning, the ring gear and housing are trying to walk around the pinion.

So rather than the car rolling over, the axle is actually trying to turn. When the axle is trying to turn, it is trying to push the left tire into the track and trying to lift the right tire off the ground. You see this as body roll, extension on the left and compresson on the right.

The springs and shocks normally control how much and how fast the axle can move. But when you move the springs and shocks closer to the center of the axle, their effects become less because their leverage is less. A stiffer spring, air bag, and tighter shock compression setting on the right side will slow down the compression. But your only option for the left is to tighten the shock extension.

A roll bar is your best bet at this point.

Re: Body roll part 2....see!!!
 

It is intirely possible that one or both of your front shocks are toast. Try to borrow a pair of shocks for a buddy and see how they work.

Re: Body roll part 2....see!!!
 

It looks to me like it has no preload on the passenger side. It looks like its darting off to the right

Re: Body roll part 2....see!!!
 

Thanks for all the input, I am gonna try putting the extra shock on the right rear and see what happens, I know an anti roll bar will be the answer but now I am just seeing what will make it better before putting the anti roll bar on the car, got under the car last night trying to pick a spot I think its gonna be pretty tough to do but I think it can be done, can you run the bar welded to the rear end and run the heims up to the fram rails? Just curious. Thanks again..

Re: Body roll part 2....see!!!
 

Here is an update, I am going to break down and buy an anti roll bar, shocks have all been tested and are fine, leafs were inspected and all fine, I did run an extra shock on the back of the car made 2 passes with the shock on each side, it helped quite a bit when it was on the drivers side, and almost felt worse when it was on the passenger side. I have made huge improvements to it compared to the first week out as now it is only bringing the front left tire up about 12-14 inches and the right front is at about 6 inches, I didn that by adding door bars to the cage, welding the bolt in connectors, tightening up the front shocks to full stiff (koni spa1) and installing rear aluminum leaf spring bushings. Not sure which one made the biggest difference but the car is at least driveable and raceable now as it 60'd 1.45's all night within .006. Just want it to feel better when it leaves if you know what i mean. I will be ordering the DM Products anti roll bar this week and installing it as soon as I get it.

Re: Body roll part 2....see!!!
 

Eric, to say the least you are making good progress. I am glad that it is coming around. I am sure the sway bar will take out the rest of the roll. One question does the car "dart" or pull to the right what you take off? I don't mean a sudden move to the wall or tree but I mean a noticeable move to the right when you take off. You are leaving off a brake right? No footbrake? Thanks again for the update.

I have been following this thread with some interest. I find it hard to imagine that a sbc would create such a problem.
I think that if you go back to before anything was changed on the car-was there a problem with body roll? If the answer is no then-what has changed? You relocated the leaf springs and rear shocks and reused the existing parts. Now we have a problem-yes? Two shocks are not going to fix it-I doubt that a anti-roll will totally cure it! So,I think we are back to shocks and springs- maybe not in that order- I don't know how you checked those-but I think that is where the problem lies. I would suggest that you talk to the spring mfg and see what they think. I am of the opinion that replacing springs and shocks will take care of your problem. I have done the same on a bbc camaro and did not have that problem.Just my 2 cents-hope that helped with troubleshooting your car-good luck!

Here is a picture of how it left before. Straight as can be.

Re: Body roll part 2....see!!!
 

the problem most likely is not shocks. One time I got to the track and found I had a broken shock mount. I just took both shocks off of the back of the car. The car ran just as good with out the shocks as with. I had monoleafs and ladder bars at the time. Car ran high tens at the time with 10.5 tire. I would check for a twisted axle tube on the rear. There is definately something wrong with the car. I have not had to use a sway bar on my camaro.

Re: Body roll part 2....see!!!
 

Eric, you have a pm

Re: Body roll part 2....see!!!
 

I think you axle tube might be turning in the housing. Check the plug welds.

Re: Body roll part 2....see!!!
 

Wow....I dig a hairy ride, but the other pics well, I put a box of diapers and a roll of tp on the dash of the TR7 when it was together, I think I might have actually needed them on that launch. Then again if I can get the chally to launch that hard Ill be in heaven.....

Something changed somewhere. Simple, I dont know enough about chassis setup on a drag car but my dad always said, "Something Changed Somewhere" the trick is to find it, 9 times out of 10 for me its the thing I was sure hadnt. Breakage bent, even on something I just checked and voila......

There is an OLD trick used on bikes (yeah yeah) but frames with low torsional rigidity like the Kaw triples and Suzy trips we used a scribe mounted to a bolt touching a pad (usually a rearset plate) Not as fancy as electronic thingies but it works....maybe one on the rear housing 1 on the chassis ? see where the flex is occuring. Ive seen 2-3 inches of flex on a bike frame of a kaw triple, hence the nickname "Widowmakers" but you were good before, now youre not something changed right ? Grab a coulple nuts and weld on a scribe at a 90 deg angle and bend it so it touches a suface somewhere itll leave a mark behind.....?

Just guessing out loud here.....wow.......that looks like it would be fun to keep straight....

Re: Body roll part 2....see!!!
 

Ernie, I didn't get anything..

Re: Body roll part 2....see!!!
 

Here is a pic from this past weekend.. Its 5 times better than the first week out but still pretty bad, anti roll should be here this week and got a few more things to check out....

Re: Body roll part 2....see!!!
 

I just wanted to let everyone know that the anti roll bar fixed and solved my issues!! I went with the DM Products bar and it fixed everythinhg. Thanks for all your help!

Re: Body roll part 2....see!!!
 

Its amazing what that little bar back there can do as far as stiffening and keeping a frame from twisting.

Re: Body roll part 2....see!!!
 

Glad to see you got it fixed Eric ! Good luck this yr !

Re: Body roll part 2....see!!!
 

So here is a pic from this past weekend at Lyons raceway park. As you can see the anti roll healed it! Thanks for all your help!
