Maybe I’m missing the point however I don’t see how some cheapo alloy collars potentially corroding in the oversized holes of the alloy subframe makes any difference provided the bolts themselves move freely. A good smear of copper slip should ensure that. The subframe itself can be easily replaced off ebay in a worst case scenario.

If you say so.  Alloy collars in an alloy subframe.  Really good for preventing galvanic corrosion, not.

The collars are anodised - so there is some corrosive protection between the bolt and subframe / subframe to body.
