Having problems getting car to roll on right rear!!!metric stub 4bar car... 600 lf 700rf 200lr 175rr... 4 1/2 split in jbar mounted just below pinion. Cars seems to lift completely on both sides instead of only on left... Any suggestions?

First off your front springs are way to heavy for an A mod. You need to be running around a 550 and 500. There are quite a few things it could be. What are your bar angles?

Another question, what is the car doing? My first thought is that you have too much angle in your rr bars causing the car to hike on the right side. With that heavy of spring on the rf you wont get enough weight transfer to come down on the rr as well. Let me know what you find. Where are you running (what state)?

for metric frame front springs look good to me. Chevelle needs much lower. Your right rear bars, especially the top must be too high to get raise on right like that. Plus jbar at or above pinion by 1 1/2" works for our metric with 3" maximum split.

It seems to be hiked ng up both sides in the rear... I was told to soften up front to 550lf 500 rf, change rr from 2" to 4", and raise jbar on frame to 6-7 split

Here's full set up
49.1% cross
55.2% rear
52.1% left
Upper left bar 56*. Upper right bar 22*
Lower left bar 67*. Lower right bar 15*
18 1/2 length jbar with 4 1/2 split
1 3/4" stagger on rear
2" offset all the way around

your cross needs to be around 50-51%, try to carry around 40-50 lb more on the lf than the right front which should get you there.
Are you measuring the bar angles while it is static on the ground or are they measured during hike?
I would pull your rr lower bar down to 5-10*, you have too much angle in the rr which is probably causing the hike. (measured angles are static while the car is on the ground)
I always liked to run at max 0.5" of stagger, you let the rear steer in the car pull you around the track. It takes a variable out of the equation that would enable wheel speed going down the chute.
If you pull the rr offset into the car you are going to get the car to tighten up (it gets on the rr faster) and it will allow the car to bury onto the rr harder.
Let me know how it goes!

If the car is raising up evenly under throttle, there is too much angle in the RU bar. Put a limiting chain on the RR. This will keep the RR from raising up and help with drive off the corner. If the track is dry and smooth, set it at 1/2" to 3/4" drop. If it's heavy or rough, add to that.

If your bar angles you gave us are at ride height (static) then the left side seems awful aggressive. That kind of angle would only allow for about an inch or two of lift. I would lower your Left Rear bars down 35-40 degrees and see if that helps
