Front and rear adjustable wheel alignment

In order to bring back on factory specs the front right wheel camber and the rear right wheel toe on my E28, I have to install adjustable front strut mounts and rear trailing arm bushings.
The only products with good references I found so far are manufactured by a company called KMac, from Australia:

Has anyone on this forum installed them? Would you recommend them?
I wonder if there are similar products / solutions from a German / European company.

Thanks.
