Just browsing the bay like you do and came across this rear brace for the E85/6
http://www.ebay.co.uk/itm/Ultra-Racing-Rear-Strut-Brace-BMW-Z4-E85-2-5-2002-2008-RE2-1176-/301035835358?&_trksid=p2056016.l4276
Now where it is located I cannot believe this can add any additional stiffness as I would have thought the rear panels which are attached at the same point are doing the same job. If it was on the rear suspension it might be a different matter.
Anybody agree/disagree?
