Here is what I am now planning to do and I would like your input. It appears that I will not be able to find an AX15 in the very near future. My BA10 is running strong but I will want to upgrade when I can. I was planning on the TNT Y-link but they are only set up for one or the other trans, sucks. So, I think I am going with the RE 5.5 kit and then maybe sell the DB & CA's and upgrade later. QUESTION*** Should I upgrade the Control Arms to the adjustable types? The kit comes with the drop brackets and I am not sure if I need one or both adjustable CA's, if any? Money is not the issue, so I will buy both if it improves the kit. Is anyone else running this set-up and how do you like it? Thanks, Rich
