And we have our first scan of the e39 touring rear suspension on the ground: https://s.digital3dcloud.com/space/f...lang=en&loop=1

I managed to get the full LCA, both diff output flange locations, lower shock mount location, sway bar position, and spring pad location. Packaging in the touring was unfortunately too tight for me to get the upper control arms completely in the scan - I think I'll need to scan a subframe removed from a car to really get it.

Well, some disappointing news. The e46 fuel tank lump on the passenger side that I was concerned about is in direct interference. And also the spring perch is a couple inches rearward on the e39.

All is not lost, there are options still. It’s just not easy now.

Did I miss it? Are you trying to fit an E39 rear subframe on E46 for multi link or otherwise? Couldn't this affect how Ackerman behaves as like, a line between the outer tie rod pivot point & front rotational axis (FCA outer ball joint) need to align with a specific spot of the rear suspension?

Yep, I’d like to make an integral link e46 rear suspension to correct for the inherent jacking problem and provide bump compliance without sacrificing toe control.

i don’t expect the rear suspension to have any effect on Ackerman as the rear axle locations and static toe won’t be changing. I do expect toe control will be better, so less unwanted rear steer, particularly to help with on-center steering feel and immediacy.
