hi i have 2008 s6 avant about to do front upper and lower arms seems to be easier if take struts out so thought i would replace them got bilstein B8 was hoping to keep original springs on it if they fit has anyone done this ? Thanks Rab,
I would say yes. I’m actually in the process of finishing almost this exact same job - upper and lower control arms, new struts also Bilstein B8s and also with factory springs. All seems well so far although it’s not quite yet on the ground. Hopefully by the end of the weekend though. Also not sure if you’ve ever taken springs off before but I cannot recommend this tool enough

I had first tried using a rental from Advance that had two pieces to it, one on each side of the spring, and not only was it prone to scratching the springs (which are freshly powder coated) but it was a total pain in the ass because I could only get a box wrench on to turn the tool which took forever. With that device above I can use the gun on it and literally get the spring on or off in seconds.
thanks for that will check out tool for springs before starting job hopefully end off week
cheers
