So I was reading on 6speedonline. Apparently the 09+ LSD equipped Cayman's differential is garbage. Matt Monson took it apart and there are 4 fiction disc plates in (2 on each side) the diff.
One would assume that this means there would be 3 instances of frictional interfaces on each side of the diff (2 on the outside and 1 between the two friction discs on each side). However, those geniuses in Stuttgart put the 2 fiction discs adjacent so there are only 2 frictional interfaces.
Not to mention there is no preload on it since it has no belville washers.
I would say that while it is not likely a Super Stock overdog, those that run them in SS are going to need new diffs yearly because soon as you get any wheel spin those friction pucks are going to be glowing red
