Is the car you are running a dirt car or an old asphault car. The reason I ask this is you are almost running our asphault setup with everything but the ride heights. If it was an asphault car there are a few more things you will need to do but this should get you started in the right direction. First is your panhard bar mounted to the drivers side of the frame or the passengers side. It shoud be on the drivers side. I have seen this keep a car loose everywhere, we switched the side and he won the next heat race running away.
The 95's on the rear seem a little stiff, we only go up to 94's on a rough track. We use 95's on our asphault car. we usually run 92's or 3's. Your rear springs seem a little light. We run between 175 up to 250. With the light springs the car may be rolling over to far. We run light springs on our super late model on a paperclip track and we drag race them out of the corner but there is NO way we could drive it through the corner on the pedal. A stiffer left rear will help with the left rear bite. A softer right rear shock will tighten up the car going into the corner. You can also work with wheel offsets to help the car run through the corner.
The springs on the front seem stiff also we run between 500 and 750 and only get above that on asphault or the front may not be rollng over enough.
As for bar angles remember the chassis moves in opposite directions in chassis roll. (drivers side goes up and passenger side goes down) You want the rear to help steer the car out of the corner if you need it to. It will be faster straight if you can run them that way but it is almost impossable but the straighter you can keep it the better. You want the left wheelbase to shorten when the chassis rolls over, the right rear should open slightly or stay in place, this will induce rear oversteer to help forward traction throught the corner. The lower bars angled up approx 5 degrees and the top link angled down at about 20 degrees to start. If you need more rear steer angle the left bar more up at the front. The steeper the angle on the top link the quicker the chassis gets traction but the sooner it looses it on the straight away. Make sure the rearend is square in the chassis and the right rear tire is about two inches inside the right front to start.
We keep our weight mounted about at sholder height in the car to assist rollover, if it is to much we move it down. Also keep in mind that you can use lighter weights if you move them farther out but try to keep them between the wheels as much as possable so it dose not act as a pendulem.

I would try moving the weight to different places until you get it to where you can get the numbers you need. Also keeping it concentrated to one area and not spread out all over with let the car react faster, but thats not possible all the time depending on your space limitations. I would add eight to get approx 52% left and 58% rear. If your track is always tacky and hooked up you could bump up the left a little and drop your rear. Try to keep them about level with the camshaft to start with and if you need more sidebite or roll when its dry you can move them higher and to the right to help get more sidebite.

You will prob need to bump up your rear spring rates as those sound a little soft especially if you get up to 57-58 rear. 200,175 or 225/200 might be better.

As for bars I would even out the bars on both sides or put the left bar a little higher to start with. Id try to line up your left side tires and have th RR stuck inside of the RF and inch or 2.
