Does Hoosier make a compound for your usage? The only problem I had with TD's was circumference differences, giving stagger. Adjusted by over-inflating the small side and heat application. The runout was always less than G'years.
Possibly yours can be trued by that's a lot to shave.
Japanese tires are always very true but I don't know what you can use.

They allow Hoosier TD's but they are much smaller and may not have the grip of Goodyears I don't know for sure just what I have been told. They also allow an Avon vintage tire but again I don't know much about them other than I believe they are smaller than the GY. The GY tires did really well in an autox I attended. I beat an experienced guy in a Z06 on Hoosiers or Kumho's and a GTR on Hoosier A6's so I am happy with their handling just not max acceleration. I agree with you about the Japanese tires, their quality control is excellent, only Hoosier A6 and R6 are better and of course any Michelin.
I will see what AVON has available in vintage legal sizes. I wonder if this problem is similar to what the drag guys get when tire shake occurs.
The drive shaft joints might not have been clocked correctly when they welded the yoke. I am going to take a hard look at that tomorrow.
