With the ridiculous Stop Tech pricing continuing to persist I'm beginning to lean towards the big pot Wilwood/AP kit with RX8 retrofit.

Here are some notable braking systems depending on your budget. You will get more "endurance" out of any of these kits. I would see which one fits your application and wheel size the best.
Are you planning on upgrading the rear brakes as well? Love your car and hope to visit Tsukuba Circuit one day!

1. Mine were packaged very nicely and I had no quality issues. I did call them a few times and didn't have any problems getting in touch with them. They are a small company and are only available during weekly work hours. Bummer you didn't get the correct stuff the first time.
2. I don't have any issues with the parking brake stuff. I do have an 06 car and had to do some forum sleuthing to swap some brackets around to get it right. I do think their directions could be better about what goes where but it was fine. I have a few SBG products and I think their quality and packaging is generally great. Probably the nicest aftermarket stuff I've bought and why I have continued buying from them. My biggest criticism is the instructions. Maybe I'm dense but two things I've bought have been a little bit different with the 06+ car and I've had to do some forum searching to be aware of it. Also, more of a focus on better pictures to show which brackets go where and how some things fit together. Example would be the oil cooler kit... One bracket to mount the oil cooler goes inside of the cooler's mounting tabs. The other, it seems should go outside. I assumed both went inside and forced it a bit. Not a huge deal but more pictures would help a lot.
3. I bought some used calipers on Ebay for around $100. I bought a Mazda rebuild kit and did that part myself. I didn't want to risk aftermarket seals and such. I had never rebuilt a caliper but it was pretty easy. Then I repainted them to match my AP calipers.
My only gripe/issue with this is that my GLoc rear pads are hanging over the edge of the rotor a little bit. I have a lip on the back of the pad from it not wearing. I contacted SBG to confirm all my brackets and everything are correct. I'm using OEM Mazda caliper and OEM pad retention clips and hardware. Idk if this is a SBG tolerancing issue or a GLoc issue. Both my street (GS-1) and track (R12) pads have the same issue. It's happening the same on both sides of the car too.
Does anyone else have this issue with the Sprint kit with the Mustang rotor? Do you have the same issue with Carbotechs?

I have this same setup albeit a NA engine so not the same level of power as the OP. I think it's a good value and paired with proper track pads it's an economical way (if that's possible) to get a no-fade brake experience. I recently tried a set of Carbotech pads and the package is awesome. Easy to modulate and no fade at all. Plus Carbotech offers a thicker front pad for just a little more so the cost per day should be a bit more reasonable.
That said, there are a few caveats.
1. I have several SakeBomb products including an oil cooler and Ohlins coilovers and the RX-8 rear brake kit is not up to their usual quality. The kit came with two left sets of hardware and no right. The replacement parts also had issues. Replacement shipping was slow. With the delays from their slow email and shipping and multiple mistakes, it took over a month finish the install.
2. The fitment of the rerouting of the parking brake was not well thought out.
3. Unless you have access to someone with RX-8 caliper takeoffs, you're going to likely need to buy rebuilds. I got them through RockAuto and less than a year later both were leaking around the piston. Only one was still available and thus began the saga of returning failed products under warranty to RA where there is no way to communicate with live people. I paid shipping for the failed parts and shipping for the new parts. And I had already paid for shipping for the originals. I gave back the savings over buying at my local part stores to the shipping companies. Let me just say that this was the last time I'll buy anything from them that might need to be returned under warranty.
I still think this package was the right combination of performance and price for me, but getting things set up has not been smooth.

It should be mentioned that effective brake ducts can go a long way to solving overheating issues. I'm running 2 in. ducts to Giro rotors front and stock rear with the stock calipers and high temp brake pads. Ducting solved my overheating and pad wear issues. I'm NA so less thermal stress than you. I never see fade or excessive pad wear. If I did it again I'd probably go with 2.5in ducts. 3 in ducts are probably overkill and make for difficult routing issues.

For me the most significant consideration for you is supercharging but you note some reletively short durration sessions. Still, I would recomend a front caliper and multi piece rotor kit with ducting for any boosted car on street tires. Generally MPH is the greatest contributor to brake temp. You still make big numbers regardless of driver skill. I have no idea what setups are supported in your hemisphere. Motorsport brake manufacturers who offer a street configuration would be fine so long as you continue to run street tires and ducts. Rear kits save wheel bearings but most ppl dont need them. Running an uncommon package to stand out is not adviseable. Embrace the local S2K track comunity, identify the non-jokers, and absorb their experience. Buy from a MFR with motorsports in their resume.
That time attack car likely wants to create temperature quickly in the one warmup lap they give themselves but also wants the driver to have fine control. The Spoon aplication may have been developed for a series whos rules limited brake rotors to OEM type if I'm remembering correctly.

Brake application and upgrade routes are so user/use case specific. It's not cheap, but the best route will be some experimentation on your part.
Nothing I've ever read about Spoon caliper being poor quality or degraded experience.
The above links are great to review your options. Ensuring quick to grab replacement parts are key. Take a route and let us know your results.
(stock hp, 255 square, 30min track sessions, oe brakes, fade at 25min and I like it)
