OK, I did it. I got a set of 12" SAW coilovers for the front. Now I've been playing around charting various (more like numerous) spring combinations, and I have some questions. Ed?
I know I can figure my corner weight once I get the shocks mounted up, since the used coilovers I got already have springs, even a few extra sets (none, I'm afraid, that I can use). But, I'd like to have an idea ahead of time, and maybe at least get one spring that could possibly work. What corner weights have you guys come up with that have already done coilovers?
I've searched some, but haven't found conclusive answers. Who remembers the spring rates for RE 4.5" ZJ coils, or 8" Skyjacker coils? I'm trying to compare to determine the spring rate I think I'll like at ride height.
So far, here are a few of my thoughts. I want 5" of compression left at ride height. I want the secondary rate to kick in after 1" of compression from ride height. I want the primary rate to be as close as I can to get the desired ride height, so the preload at full droop is minimal. I want the total spring force to allow full articulation at 10.5" of compression, the last 1.5" is for the fast stuff.
I don't have Excel at home, so I can't play with Ed's spread sheet, but I've charted a bunch of combinations by hand, and the biggest problem I keep coming up with is blocking on the lower coil at full compression when it looks like I get the spring rates close. Now, I've been using 1200 lbs as a corner weight, because I have a bunch of stuff on the front of my rig, and going from what SeanP posted as his corner weights. As I've looked back through previous threads here, the couple of times corner weights are mentioned it's much lower than I'm figuring.
