I currently have bilstien 5100's all around, removed x-reas and 2in spacers in the rear. I picked up a set of 2012 fj springs with less than 1k miles for $45 and want to install them. How much should I expect a shop to charge me for installing the springs and adjusting the bilsteins to 1.75 from .85 and keeping the spacers in the rear? This isn't a job I have the tools for to do myself. Thanks for your help. Love this forum.
