Played with the alignment more today as it was easy to see it had too much positive camber even after maxing out both cam adjusters. I was running the jba ball joints mounted to the bottom of the control arms to keep spring contact from happening. This of course kept the arms higher thereby causing the camber issue. I switched them back to the top, the way jba intended which fixed the camber issue and it drives way better. I figured I could have spaced the suspension cradle to compensate, but figured it'd be better and easier to move back towards stock height than adding more complexity. I'll be reducing clevis lift later this month when my cv boot arrives. Who needs 3.75 inches of lift anyway.
Also learned something else I forgot to mention earlier. The rear IRO uca allows 2 more inches of axle droop over stock measured at the spring seats. And even more flex when one wheel is stuffed and the other unweighted. So much so in fact that I'll have to extend or lower rear brake line. And my rear springs (948's) 2 extra upper iso's reach a point of zero tension. Not enough to fall out but more than I like. It's unlikely I'd ever see this situation in the real world, but I may do a temporary shock mount mod to limit extension. I'm currently running bilstein 33-185859 (be5-a702) which have an extended length of roughly 25.25 inches compared to the more popular 24-185240 that aren't quite 25 inches fully extended. If I had the later I probably wouldn't be even considering messing with it.
Thanks for sticking around. Loving the 4.10's, IRO, and all the other fresh bits and pieces so far. However I have very limited drive time on it.
