No lock up in the rear and the car just jiggles left/right, just like the Cayman would
Actually it is a "wear item" just like the rotors, so normally they don't replace them under warranty. However, with so few miles they thought it is appropriate, which I agree and am pleased. I asked them if they can actually replace the clutch pack with the motorsport one, they are going to check and let me know.
A friend of mine had the very same issue with even less miles on it with his GT2 that already had GT internals. So, from a durability perspective, that may not be the solution either, although the GT2 puts out a lot more torque than the GT3. So, I will see what I can get from the dealer, and I will also talk with Levitas as he is an expert on diffs IMO. Mike will be out of town next few days though, at VIR with Bman and Trakcar
Their gonna have fun, while I am waiting at home for a diff
