I currently have a 2.5in level in the front, shocks seem shot after 90k miles. Just delivered were Bilstein 5100 ride adjustable front shocks plus 5100 rear shocks. Looking to replace current level with Bilstein fronts set for 2.5in level, will this make the ride rough? Also looking at add 1in or 1.5in rear block while 5100 rears are being installed to help with the occasional tow. Any recommendations? Does this seem like a viable option?
