I have yet to make up my mind. "Speedway Motors" is local to me. In the catalog, the QA-1 do not have a name like "Proma Star" and the counter guy's did not know either. It just Say's, "12 position, adjustable street rod coil over shocks" So, I have no idea if their the Proma Star. The good thing is, if I pick the wrong springs, I can take them back for a different pair. They are $400 + tax.
I would appreciate you guy's that use these to look at them on-line, or if you have the catalog, and see if their the same shock you have.
