Anyone run this? We run a 3400 lb car and for some reason we are getting excessive body roll and need to tone it down. We run 250 on the LR and 200 on the RR right now. What would happen if I swapped those? They are the same length. We are running about 51% rear and 55% left right now. I don't know if I can get a 300 lb spring or a 275 or something before Friday. Thanks.

we run the heavyer spring on the right side.Our body roll improved when we removed the biscuts between frame and body and replaced them with bolts and washers.Suck that baby right down on the frame.

The body is already welded to the frame. The roll is in the suspension.

mod75d took the words right out of my mouth. I had the same problem last year. I took the junk shocks out an replaced them with som proshocks and it was night and day....

Do you have any lead mounted high on the chassis? If so, you can try lowering it which will lower your center of gravity and will decrease body roll. Just a thought.

Lead is mounted on the trunk floor right above the rear end pretty much, about 51% rear right now. The shocks are brand new carrera stock mount shocks, and they are in good shape. I didn't check the amount of travel. I will check soon. Thanks.

My personal opinion is on that heavy a car I would run a heavier spring on both sides in the rear....Like I said everybody likes a different feel....Towman

It should be cheap to try running the sway bar(s)I took it off mine to get the body to roll easier.The real name for it is anti-roll bar.

debates about "real" name aside ......
if it helps some folks to understand the function ... we can call it an anti-roll bar as well.

sway bars are often available in many sizes from different stock applications ... for example, if you wanted to fool around with various bars on the back of a Camaro, they can be found (on various models of Camaros and Trans ams)in the following sizes:

9/16,
19/32,
5/8,
11/16,
3/4,
& 13/16

keep in mind that sway bars(anti-roll bars)
vary in rate in an amount directly proportional to it's diameter to the 4th power.... so a 3/4" bar while less than 50% thicker than a 9/16" bar has a rate that is 215% higher (a hair more than 3 times the rate).
