I received my AR330535 steel turnbuckles yesterday! These were listed by Tower as "upgrade parts...order pending" for the Mega 4x4. This plus the link end sets I bought when I ordered the Granite, and now I have adjustable turnbuckles and camber links (on the front, anyway. I'll need one more set to do the rear camber links). Now my front wheels are toed-in slightly (instead of being toed-out kinda significantly), with about 1degree of negative camber (tilting in ever so slightly). Big difference? Nope, but it does seem to track a little straighter/better at high speed on pavement than it did before. This in spite of the fact that the steering is a bit sloppy on these kits (even after doing what I could to tighten it up a bit). Anyway, if these really are "upgrade parts," how far behind can the other more important upgrade stuff be?
