If the shocks are still attached, it definitely won't lift, but I've found that the 1.2's are very thin.

Moving the roll bar arms as you have mentioned changes the tension on the roll bar, you might as well fit a thicker roll bar.

i'm talking about with shocks not attached i cant get them to lift anymore it .

question is will it still do the job its put there for or is it a must i get arms to move with shocks detached

If they are attached they are doing their job, it's just that the effect of a 1.2mm is less pronounced so to your eyes, it appears to be doing nothing.

Try removing it and see.

If you use outer bar position on the arm, the arms do not have to lift with 1.2 bar but it does not mean that bar is not working. Try to drive without bar and you can immadiately see the difference. You can see that front arms are moving because front bar is harder.
