I’ve got stock, non cup struts with lowering springs on a 197. Would they work with those? I’d like to be able to add some camber and these seem as cheap as power flex camber adjustable bushes (if 1 unit price means you get 2 top mounts). What’s the catch? I was thinking about replacing the top mounts anyway as part of my suspension refresh (just ordered all new swivel joints) so will have everything apart anyway.
