Okay so I am looking to upgrade my stance a little bit and was thinking of adding 10mm spacers in the front and 15mm spacers in the rear. Along with the spacers I would like to get either H&R or Eibach springs. I'm definitely looking for a meaner look with hopefully a slightly more than 1" drop. Would this combination be safe to run on an otherwise stock Xdrive suspension? My car is a 2011 Lci N55 xdrive MT coupe if that matters. Any advice would be greatly appreciated as I am lost in this topic.
