Adjustable Strut Rods

I have a question. If you were going to run bias ply tires today, would the above settings still be correct or are there updated numbers for that? I would think (I could be wrong again) that even bias ply ties have gotten better since the 1970’s.

What do you think?

Honestly, I've never looked into it.

I would agree that even modern bias ply's are probably constructed differently than the original tires these cars ran. Radial tires have changed a bunch just in the last 10-15 years, and the new modern radials can take a more aggressive alignment than the older ones could. So it's totally possible that you could do better than the factory alignment specs with a modern construction bias ply tire.

But I haven't looked into running bias ply's on anything recently. I know Coker has some replica's out there for those looking for the original look, but I don't know enough about their construction to say much. Some of the drag race tires are bias ply's too, but I would think that if you were that serious about the 1/4 mile you'd be running drag race alignment specs too, which are closer to bias ply specs anyway. Mostly close to 0 for everything to keep the rolling resistance down.
