Slicks to Leaf Spring Space?

Well the only reason I´m start testing the narrower rim, is be cause this was how the SS/B cars ran back in 1968.
Possibly was the slicks more stable back than, but not much... If it ain´t gonna work, I add an inch at a time. But the fact still is, the Landy Dart pictured in post #4 was running 125 mph on 6" rims 10,5" slicks just over 10 psi. I will start with this combo, and work my way up, an inch at a time, till the ride is "safe".
Thank you for your input.

You want to kill yourself on the big end have at it.

Fact is the people who make the tires know what's right for them and reinventing it with 1960 ideas does not sound like a sound idea.

I just watched street outlaws last night and seen two cars jumping the guardrails and barrel rolling because they lost the back ends

I would go with two sets of tires. One for show/pictures and another for the track if you going to race it if your dead set on the look

IMHO
