Adjusting springs corner to corner seems vital, especially on the 05. Adjusted mine when it was misbehaving and it was 100% better immediately.
In 07 news, I ordered a super shorty pack, because returning to a full size lipo feels like de-evolution to me. I'm may be wrong, as I often am. The upshot is it was only $20 after discounts. The downside is I still don't get to drive the car until end of September.
