Jaguar IRS Trailing Arms

Unless the front end pivot of the trailing arm is in-line with the lower control arm pivot axis, you need some compliance somewhere. ERA accomplishes that by rubber mounts at the top of the subframe (that contains the rear suspension main assembly).

So the body mounted side of the trailing arm has to be in line with where the LCRs mount to the Axle?

I actually have trailing arms installed, one end has polyurethane bushes and the other has a hiem joint.

LCR?? The inner axis of the lower control arm should ideally project forward to the front mount of the trailing arm.

LCR (Lower Control ARM)

"The inner axis of the lower control arm should ideally project forward to the front mount of the trailing arm"

Thanks for this, that how I understood previous comments.

I am actually only a few inches out, I can build some brackets that lower the trailing arms so the body pivot side is at the same level as the LCR inner pivot.

Yea, thought about a watts linkage, that's allot of work. Here is another Watts option, this would be easier to fabricate.

Made adjustment to the trailing arm mounts, I welded on two tabs that allowed me to lower the fulcrum point to be at the same height as the LCR inner fulcrum point.
