That's a great choice on the brakes.
The 6 piston setup has better total heat capacity, leverage and more availability on track pads. Go for the C7 Corvette ZO6/GS iron calipers which have vented pistons. That is what I have and it slows the heat transfer into the fluid. I repainted mine with G2 caliper epoxy and applied ebay decals. A little bit of aero helps evacuate the ducted air out of the wheel/wheelhouse better, I have the ZL1 fender deflectors and my own extensions to create a low pressure area at the outside of the wheel.
I also run Girodisc titanium shims to help slow heat transfer into the caliper. Yes, the rotor will see more heat, but the correct choice of pad that has a high limit on temps will keep fade away.
Get some air to the rotor, find a more aggressive pad, sweat the details, keep fresh fluid in the calipers, and lay eyes on everything before every track day.
I run the ST43s on the street and track. They are well known for their durability. And, as demonspeed mentioned, their noise on the street, haha. They are one of the more expensive choices, but Porterfield and Raybestos-Racing.com both offer discounts. When you take into account that they wear excellent, then their cost is easier to accept. Their wear won't be quantified in just two events. They'll go longer than that. My observed rotor wear shows the ST43s are easy on them. You'll toss a set of front rotors due to heat checking before they reach minimum thickness. Non-corrosive brake dust, high temp limits. Very good torque. On the street, even when the transfer layer is wiped off, they have excellent cold bite.
You'll get alot of opinions on pad choice. See what the more experienced Gen 5 and 6 owners are running, like Jeff9962, or even the fast Mustang guys. Look for similar weight cars to bring the opinions on an even level.
