This is common suspension knowledge, and while I'm not always the best at explaining things I'll give it a go.
The upper spring perch is fixed. The shock changes angle during suspension movement, while the upper spring perch doesn't. This loads the spring unevenly, which bows it, which is what causes the rubbing. Move the upper shock mounting further up, and the angle difference between the spring and shock increases, making contact more likely.
Both of my GC sleeves in the front have missing threads from the spring rubbing them.
As for the side loading, the same forces that bow the spring force the shock to bend. Stock, the shock's upper mounting location was already less than ideal. Relocate it further upwards, and you increase the wear on the shock's seals and shaft.
ahh, i see what you're getting at.

GC extended upper mounts, hence my sleeves missing threads
I thought I would need the upper mounts at one point (I've played with various parts and alignments). I have dented shock towers from the UCAs thanks to them. I'm not worried about my shocks, and would simply have them re-valved if the added stress kills them early.
I have extended tophats, Lotek short struts, and junkyard coils lol, eBay camber kit running about -.8 to -1 idk but my shock tower is cut open atm and when I drive the arms of the uca still hit in the upper wheel "well". It seems like it's going to hurt the shock with the sudden stop in suspension like that. And my ride quality is poo
My oil pan is about 2 inch from floor and I like that the suspension stops from scrape
