Body roll

Not sure about the RF arm, my best advice would be to leave it alone if your frontend settings are good.

I'd go up on the LS weight, set the front ride heights level, set the rears about 1/2 to 3/4" higher than the front. Put the 200 back in the LR, try about 55left 52-53rear 50-51cross.

Shouldn't be any reason that won't work for you, as it is, you're working the RR to death.

flattop, disregard anything I suggested, ask Jeff J for help, he knows the only way to make it work.

Going to switch rf a arm. did not have any camber gain. 9 inch spaced 1 inch inside mount to 71/4 outside.mount.

Thanks for the info i am going to put ls weight. checking frontend settings. i think i got the upper on the right its a 91/2 spaced about 1 inch inside the mount. if i put a shorter arm would it move the roll point over an not roll as bad? thanks again.

What my question was about the upper arms was to ID if the inner mounts were above the frame by say more than 1 inch. To get a ballpark roll center on the metric frame you need the arms mounted close to the frame and tall upper ball joints as the rules allow. Roll center affects spring rating as well as other other things.
Shortening the arm length will add more angle in the direction you want, but will affect you roll steer, bump steer. I would'nt change that to correct your concern. You are in the ball park now.

You have done some work, but have not mentioned your shocks.

Check the shocks and tune with them, one or two number change will take out a bottoming. Drop the springs down 900 lf and 1000rf, you will increase you forward bite when you get weight transfer from the lighter springs. I cant imagine how you can drive a rough track if needed. A 1450 spring would beat your eye balls out of your head on our tracks. LOL. I tried a 16 and 20 inch LR springs and saw no advantage. I run 13 inch and my car has plenty of LR bite.

Went to 7" a arm to get 1 degree camber gain. my a arm is about 1/4 off the frame on the front an level to the back. 74lf 75rf 93rear.
