Rear axle Caster setting

[RJacobsen]

I have been trying to find the rear axle caster setting for the Jag IRS without any luck, my guess is that it is similar to the front setting (1-2 something degrees positive) but need to have some verification before I continue with my current project.

Rod:

According to page 20 of the manual that came with my kit the specs are as follows:

L & R FRONT CAMBER SPECIFIED RANGE:
0.3 DEGREES NEGATIVE TO 1.3 DEGREES POSITIVE

L & R FRONT CASTER SPECIFIED RANGE:
0.1 DEGREES POSITIVE TO 1.6 DEGREES POSITIVE

L & R FRONT TOE:
1.5 MM

FRONT CROSS CASTER:
0.7 DEGREES NEGATIVE TO 0.7 DEGREES POSITIVE

FRONT TOTAL TOE:
3.0 MM

L & R REAR CAMBER SPECIFIED RANGE:
0.5 DEGREES NEGATIVE TO 0.5 DEGREES POSITIVE

L & R REAR TOE SPECIFIED RANGE:
1.0 MM NEGATIVE TO 1.0 MM POSITIVE

REAR TOTAL TOE SPECIFIED RANGE:
2.0 MM NEGATIVE TO 2.0 MM POSITIVE

REAR THURST ANGLE SPECIFIED RANGE:
15.0 DEGREES NEGATIVE TO 15.0 DEGREES POSITIVE

I suspect that if your plans are to race the values will differ.

Thanks for the info Stan. But I may be using the wrong word here. What I am looking for is the alignment of the rear suspension control arm in relation to level front to back. I am trying to determine if the rear axle (which hangs from a top mount) needs to be tilted forward or backward from a "level to ride Height" position and thus changing the direction of travel of the rear suspension from straight up and down to slightly forward or backward.
