So it's listed as having an Electronic Limited Slip Diff, which is what I think you're describing, although you're not calling it that.It does not have a Limited Slip diff. It has a virtual LSD where the ABS system applies the brake to the wheel that is spinning in order to move traction to the other wheel.
OK. So Wikipedia describes the different types of eLSD, and one is the "brake type", which is what Jim910 and silver06hemic describe. May I ask - how do you know that this is what the 2015 300 uses?So it's listed as having an Electronic Limited Slip Diff, which is what I think you're describing, although you're not calling it that.
As I google eLSD, I'm becoming increasingly confused because there are differing descriptions... (?different types of eLSD)
I purchased it through and had it installed by High Horse Performance in Smyrna, Delaware. I live in New York so it was about a 2.5 hour drive down to their shop for me. They did it in less than a day. Actually I had headers installed the same day and they look longer than the diff install.I know this post is old, but do you remember where you got it from? I may look into getting one for my 2013 300S 5.7.
