BMW E39 M5 rear ARB retrofit & Arnott rear SLS bags review
Discussion
The ARB removal & replacement is an easy job to do; once you've undone the spinning-in-their-socket rear drop links 
Fitted this last week; fitted along with Powerflex purple poly bush bushes and new Moog rear drop links. Arnott SLS bags fitted also
The Powerflex bushes are a tight fit in the OEM ARB brackets; but they fitted fine with zero issues, just used mole grips to keep them in place as I did the nut up etc
The ARB has made a noticeable difference already; just driving along the country lanes local to me on the way to training and back; the car takes the bends much tighter and the rear end has lost its tendency to lean a bit too much, more so on the tight bends with weird camber etc The car just feels so much tighter; it didn't roll stupidly before I did this retrofit; but it was noticeable. That's all but gone now!
The Arnott bags are superb also; they've quietened the rear end down when it comes to overall road noise and bumps in the road etc. Although the bags on the car with the originals dated 2002; they were 'well used' and due a replacement, really glad I've done that! The car does sit slightly higher than before also, so may look to adjust that in the near future; but it's only a few mm really
If you've a Sport touring and haven't done these upgrades; I'd highly recommend it!
