Last summer I purchased a used carrier from MustangEddie, because my spider gears were shot, and had a local shop install new carbon fiber clutches along with new axles, and axle seals. I provided all of the parts and soaked the clutches in friction modifier.

Shortly after I got the car back, I jacked up the left rear and was able to turn the left rear wheel/tire with a little bit of effort. I thought I read that it should take about 200 ft/lbs of torque to break the LSD loose?

I run several auto cross events each year and I'm still spinning the unloaded wheel around corners.

Is it possible to install wider discs or a stronger spring to tighten up the LSD?
