Your plan and thoroughness is great. I appreciate your taking time to post results. It's invaluable coming from guys like you that are pushing the car's performance envelope and very educational for us slackers. Morris' build and testing was of very similar benefit-but you're doing it with an original. If that's a limiting factor of your car's performance, it hasn't shown it yet. Great accomplishments from both of you. It's what I come here for.
Thanks from me.

Chas, I wish I could but the run out exceeds tread depth.
I took the tires in today and had them balanced on a recently calibrated Hunter.
left rear was 2.75 OZ off, Right rear was, 2.5 OZ off, RF was 1.5 OZ off and LF was 1.0 OZ off, so much for having them balanced at the track race shop.
Perhaps the imbalance coupled with the large torque load was enough to cause a stick slip in the tire and the resulting vibration, I hope so. At least something was wrong, I feel a little better about it now.
