- 2011 M3 convertible
I went from an STI to an M3 because my ringland on #4 cracked. It's significantly different, I'm speaking of AWD to RWD. While I don't have a Mustang the weight of my convertible and power is similar to a 2015 GT.
I had a pro-tune stage 2 and you could just mash the pedal even in the wet and it would hook up, it would push more in turns but you could put the power down much easier. Also there is about a 400+ pound difference which you will feel in any turn.
You just have to be more selective in applying power, even with snow tires on on cold dry pavement I'm triggering traction control at anything past half throttle in 1st gear.
Money-wise you are going to get murdered. Personally I'd wait until late spring unless you are in the deep south.
One note on performance of the STI to the Mustang, stock to stock the GT will put a hurting on an STI at a track. Here's the thing where you may see a GT with and exhaust switch and a tune the average buyer of a GT will probably keep the car stock. Almost no one will keep an STI stock so expect every STI you see to be making 20%-30% more power and Torque than stock numbers and be 400lbs lighter while on traction limited public roads.
