8 deg. caster with 35's?

With the toyota axle swap complete I managed to drive the Jeep down for an alignment last week. Caster came in at 2deg (R) and 2.2deg (L). It's what I expected as the toyota's came with between 1 and 2 deg from the factory. When I upgrade the front axle shafts I'll cut and turn the knuckles but for now I'm just going to correct it with shims so I can drive the thing.

So, I can get 4 deg shims that puts the caster in the mid range of spec or I can go with 6 deg shims to put it around 8 deg. I've read several people suggest to go with a higher caster angle when running 35's or larger. Just wondering what the consensus is on that.

Thoughts?

The advertised position for a topless, dirty jeep girl has been filled......by my wife. Thanks to all that applied.

6-7 degrees works fine for me.

I want just enough caster for good handling. Good "return-to-center" and good tracking at speed. I've always been able to get that with somewhere between 4-6 deg or so. I'm sure there is such a thing as "too much" positive caster.. where the front tires flop side to side too much. Just not sure what that number would be.

Might try the 6deg shims and see how it rides.

Mike go with the 6 degree shims as things settle down like your springs and such you will probably see that shift into range.
Now the upshot Mike is you can claim your Jeep is acting squirrely and its not the Molsen Golden on your breath.

Thanks guys. And George, if only something so simple would convince the fuzz it's not the operator, lol.
