What type of track? High bank, flat, momentum or stopngo? Where is the pull bar on the frame and rear end left to right wise? Air pressures?

Hasben- Why would you make the same post on two different sites and not give everyone the same information? Call your chassis builder.

Agree with Lightning. Also if the car worked good with aftermarket lowers and a straight bar, go back to what you had. JMO

Some people do not monitor both sites. i broke our problems down into 2 areas. Within reason all of our problems start with body roll. we have tried everything that has been recommended at some point in time. We have been in constant contact with the car manufacturer. Bottom line is our problem persists.
We all agree that you have to get into the turn and through it. Driver has said car was good going in, but a little loose in the middle. We fixed that. We checked and found that rf was not planting as it should and that the rf shock was only getting 2" travel. Hence the question about body roll. The car also does not have the forward drive that it should have. When other cars are going forward - we aren"'t.

Switching from a straight bar to a j-bar will require more angle.
Body roll is a bi-product of weight transfer, not the other way around. Weight is still transfering without body roll.

I would soften both right side springs quite a bit. Assuming this is a chevelle stub I don't know why you would run stiffer than a 500 or maybe 550 on RF. We are significantly lighter than that and get tons of forward bite with our car. I would think a 175 would give you quite a bit more forward bite over what you have now also. Probably can't do that without washing the front unless you go softer up front.

I tell everyone its a real ballgame! Too many factors to just guess but if it wont hook off the corner there is no weight on Lt. Rr. tire. Swap ft springs, softer rf shock. 200lbs left rear with 60 plus rear percent. And hang on!

Unless I missed it in reading thru this, are you even on the LR Spring when you pick up the throttle? If you are up off the spring, adding LR Bite will loosen your entry, but isnt really giving you more bite coming off.
If you have an in car cam, put it on the car where you can see the drivers hands, and watch what hes doing getting into the corner possibly?

How experienced is the driver. Sounds like you guys are chasing five different problems and have a solution to all of them but when you try none of them work.

drivers are all experienced. The latest has been driving for probably nearly 30 years. The other 2 for quite a while -10 years.
