The Cragar “trick” was spun aluminum. And that is why it was stated to not use on the street. It was fine in straight line use, but repetitive turning would pull the lug nuts through the wheel, along with stress cracks and bending or warping the rim. C-lines could run on the street and tubeless, I don’t believe tricks could run tubeless either?
Listen, I am no expert on these wheels. When I was 18, in 1979, I had the dream job of an 18 year old gear head. And that job was working in a speed shop! Between reading catalogs and talking to reps, I picked up what I know. I was a sponge for this information.
