I don't know if any model of Mustang comes with an open differential. You should have a posi traction or limited slip differential so you get power to both wheels. That and a good set of snow tires and your set. I use a F-150 4x4 for my daily vehicle. I used a rear wheel drive vehicle for many years though. 340 dusters and darts. I used snow tires on the front wheels also.
the summer tires are good down to around 40F. And at that they probably provide less grip than a decent All Season. If it were me, I would find some all-seasons with good consumer reviews, such as found on tirerack, and put those on.I'm in the same boat. Been driving FWD cars forever. I'm pretty intimidated to drive in the rain right now. But I have the PP Pirelli tires on it, sadly.
Was thinking to swap out to Michelin Pilot AS/3s immediately. Make a big difference in rain?
For winter, that's why I have a daily driver Toyota.
I wouldn't exactly call it "re-learning" . . . what you need to be doing as you drive a higher performance car than what you've been accustomed to driving is making ALL of your control inputs "smooth". Ideally, you should learn to tell from the way the car feels that it's getting close to coming unstuck - there is a little warning before all hell breaks loose if you're paying close enough attention, so this can be learned . . . if you aren't blowing through that little warning so fast that you can't pick up on it.
Generally speaking RWD cars will have better weight distribution vs a FWD car however, weight is good thing on the drive wheels in the snow/icy condition so a FWD will normally have more weight on the drive wheels than a RWD. But RWD also allows better weight shift than FWD because FWD when accelerating tends to lift the front where RWD shifts the weight to the back for more grip.
