Greg the best bet is to do the simple mod to the genuine GM brass part. To answer your question, proportioning does not begin until a certain pressure is reached, then it is a percentage reduction to counteract the self energizing forward shoe characteristics. But per Dave’s article it was not utilized in the steel assembly line part. GM service parts switched to brass because they knew about the rust issues. But by then GM no longer supported TZE as all that had already been bought out by Cinnabar. Personally knowing of the corrosion issues, I would only want brass and made in USA
