How the hell did you use this tool to pull your ST springs???
The tool bottoms out before it's even close to compressed.
Trying to use one coil higher or lower requires the smaller cup, and the tool won't seat level using the smaller cups on next to outer coils.
You can see the tool bottomed out. It's dumb that the retaining bolts face each other. That's what's butting together and preventing any further compression.
