I have always wondered if there was enough preload to cut a coil or two to get it down to 8fpe.

There's only one way to find out. It's easily measured. You should leave some preload. Too little can cause it to twang. Most Vortek kits run a lot less preload than factory and ARH and they still work well. That's not just length but also pressure. Vortek kits are more easily assembled without a spring compressor than the others.I have always wondered if there was enough preload to cut a coil or two to get it down to 8fpe.
