I was a bit suprised aswell how loose the bolt fit into the arm when my parts arrived and i test fit things while unboxing.

Went on with the install and seems fine.
I was lucky, Turner Motorsports had the full set TRW control arms, bolts and headline level link. Took a few weeks but I was not in a big hurry.

I suspect the bolts are mostly clamping the Frame against the bushing. I'll go ahead and swap everything out sometime during the Christmas Holidays.
