I *think* the OEM inner tie rod has 70mm of total thread length, the OEM jam nut takes up 10mm of thread length, the thread diameter is 14mm, so its ideal to have 150% of diameter as thread engagement as minimum into the tie rod(aka steering rod), which is 21mm of thread engagement. So in my opinion if the inner tie rods have near 40mm of thread length showing then its too close to danger zone. Which is why for the more aggressive track setups we make longer outer tie rods(aka steering rods) shown in images below.

It looks like my LCA inners ran out of thread at only -2.4 degrees camber up front. Does it sound like something is off or is that just how my car is built? Can't recall if there is an eccentric bolt that can also affect camber.

There is some adjustment at the top via the front strut tower slots. There's no eccentric bolt at the front. We make longer LCA inner to extend the camber adjustment range for more track focused setups.

Thanks. That’s a bummer. Maybe the easier thing to do in my case is then to max out the shims and then go for camber plates. Or just live with -2.3 to -2.4.
