Zip ties from shock cup to spring won't do any good. The spring has an open end and will work it's way out of the zip tie.
You need to close the opening in the spring cup. If your cup don't have slots or holes in them, make some. Then run the zip tie from one hole to the other to close the opening in the cup and you won't lose the cup unless the zip tie breaks.
Or you could just unass some money and buy some hi quality C cups."thumbsup"
