Spring smashing 5th coil

[Crash101]

Anyone smash there fifth coil to the centers? What's a good weight to be at? Any good dirt here would help. We've always got the car to ride height and run the nut to the spring and add a turn. My center are 18 3/8. Thanks

I just smashed to the travel indicator and wrote down the center to center and the load, put on my stack and locked it out to where I got the same # on the stack as I did with the standard spring. I could tell a big difference just by doing that. I think that was with a 300 on top and 800 on the bottom, it's been a couple years.
