Play with this suspension calulato to see the effect of arm length and mounting points at the frame and spindle. Try to get negative camber change throughout suspension cycle. Try minus 1 to 2 at full droop and minus 1 to 2 at full bump. If it gets to zero as it swings up or down it whold be all right. Positive camber is not good.

Hi Gene
Thanks for the link! i've put in the measurements for the front suspension ( well i've shortned them both by 4 inches (100mm) cause they wouldnt fit in the window. heres a link with my settings :
linky
As you can see from link, the upper a arm is actually 2" shorter than the lower.
