Tucker,
Have you got the exact URL to the ARB links i can not find them on LMF.
As for tracking, once you have got it all done take it to a speacilist and get it fully laser aligned, it isnt that cheap. I had mine done after havong all my bushed changed to poly ones at a rally place. Some higher tuning companys also offer it but check out the price as it can vary from £60 to £200.
