Considering a Cobra have some questions

[Detroit Bill]

A couple years ago I was able to live out a life long dream and get a Porsche 911S 2012,(991). It is an awesome car, fast and handles like a dream.
What I found over time is that to get a thrill out of it I need to be near the edge. The problem is that the edge on that car is way out there. You have to be going very, very fast and doing something pretty crazy to find it.

That leads me to consider selling it and getting a Cobra. I am looking for something that is a little more weekend machine and more raw obviously.

First question (I have several). I am going to guess these cars are a bit squirrely. Short wheel base, light, lots of power, stands to reason. I am good with squirrely but how squirrely is it?

Second question. If it is a handful does swapping out to 17 or 18" rims with modern rubber make a dramatic difference? I understand it is not period correct but it still looks good.

I'll start with thouse two questions and see how it goes.

Thanks

Bill
