Freed Engineering in Millersville, MD did the install. I think they ended up charging $1200. They originally estimated $800 but the diff took longer than anticipated. The $1200 was for installing the OS Giken LSD, BC Racing coilovers and FIGS Engineering lower bushings. If you had to break down the cost, it probably would have been $700-800 for the diff by itself. While Freed Engineering did a good job, I would have preferred to come to you guys, but the price I was quoted was simply too high. I called your shop and was quoted about $1300 just for the diff (10+ hrs labor).
Just an FYI, in the future I would love to use your shop for all my installs as it is probably the most streamline and professional shop in the area. I will not use it though if it costs 1.5x what I can get at another shop that will do very good work as well. I am mentioning this just for your awareness as a business owner. BTW, please continue to keep up the good work with the ISF parts. Thanks.
