Red,

I just want to add that there's more to it than just too much rubber (with 18 and 19" wheels) and relatively low power without LSD for such a good chassis like that in the Cayman which leads to understeer.

The fact is that you can't switch off the DSC (Dynamic Stability Control) permanently, which is a petty!

When the system detects a wheel speed difference, right and left, above a predetermined threshold it will actuate making the Cayman to understeer. Thus, a LSD would be of some assistance here too by retarding the DSC action.
