So I'm curious, do you even bother balancing them the old fashioned way if your going to use Centramatics?
My truck would be a real challenge for them. I've had a vibe at a very specific speed for years. I posted here about it but short story, I've changed wheels and tires and had everything checked out. The only thing that helped was going to a much heavier tire but, it still does it slightly. We've even run it with all fours off the ground and it's smooth as silk.
