Slicks to Leaf Spring Space?

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

Actually two sets of tires is a good idea. But again, you just don´t jump in and nail it on all four gears. As always with a new build, you start with first to second gear and than let off. Even take slight turns to see how car reacts.
If nothing works other than 8-10" rims, well, that´s it.
But this build is a piece of history, and I will not give up easy.
Hopefully car is on wheels next summer. But finding 15" steel wheels and old school slicks takes time and I like to be ahead in planning.
Again, thank you for your input.
