I'd go with 4* shims up front. That will put you at over 7* total (a little over spec). Even if the springs sag a little more, you should still end up at about 6* which is about perfect IMHO. Just make sure to get some good steel shims that bolt to the spring pack.

From the 84-86 FSM;

Mine handles best around 7 degrees, so I'd go with the 6 degree shims, as RaiderFan (aka Gmakra) said.

Help me follow this print out. The top two boxes show a 3.1 pos. degree caster on the left and a 3.3 on the right. But when it (I assume) combines them into a "front" reading, they become a -2, and what is a "cross" caster. Not following this printout.

I don't understand the combined reading either but you just made me realize I need 4* shims and not 6. So thank you lol! I need to get ahold of quadratrac ASAP

It says -0.2 not -2. I assume that "Cross caster" is just the difference between left and right caster (3.1 - 3.3 = -0.2). Seems like a fairly useless piece of information, but it makes the printout look impressive

Oh yeah duh! Guess I shoulda looked closer. Then I would suggest a 2 degree shim. That would put you within the range at 5.2 and closer to the target of 6 degrees.

Update: I've had the shims in for a week and I'm pleased. I've been in many-a-CJ and I don't recall a smoother ride. Between the new springs and the proper caster it still a jeep, but handles very well. I also have new TRE' s that are going in soon along with a drag link flip
