Opinions on a rear strut?

Okay so on german ebay a rear boot strut keeps popping up. I've searched and searche'd and can't find any opinions on this. So my question is, will this benefit the car whatsoever as it is fairly good at handling and have little body roll and also would I be best off getting a front one to that goes underneath where the windscreen is? Opinions please...
 
From experience I can say the rear strut bars that fit in the boot or across the rear struts actually do bugger all on these cars. The front strut bars and rear arbs make a massive difference though.

Do you have a link you could share to the brace? I can't really contribute to the performance of the boot struts, but I have been eyeing up the UR one for a while; interested more in form over function since removing the rear seats.
