Keep in mind that the sprint kit includes braided lines, so some of the feel is coming from there compared to stock if you are going from OEM to Sprint.
I was running CSG C1 pads with OEM rotors on the front and I switched to AP Racing Sprint w/ DS3.11.
I wouldn't say they are worse than the stock setup I had, but they aren't appreciably better either. I didn't say that they didn't work, I just said they're a waste of money.
There is talk of this being cheaper in consumables, but I don't see how that's going to work out. The AP rotor rings are not cheap and there are no third party options. OEM sized blanks can be bought very cheaply. And while the pads are slightly thicker for AP, since the setup weighs less overall you're putting a lot of heat into the system.
The spreadsheet you referenced doesn't list brake setup so that's neither here nor there. A lot of people might run the sprint kit, but a lot of people go to McDonalds everyday, that doesn't mean the food is good.
At the end of the day it's your money, spend it how you see fit but in hidsight I would have done Brembo BM4 or maybe the Stock Brembo setup or maybe AP endurance, but not Sprint. It just doesn't deliver enough value over the stock seutp for the price. YMMV.

Myself and my group of friends have been tracking these cars since 2013, on OEM brakes originally, then made the move to the AP Sprint kit. Of the 5 in our group, 3 are dedicated track cars (not used on the street), 2 are dual use (Street/track). All now use the AP Sprint kit. This weekend will be my 38th & 39th days on track in 2023.
It is important to note that most people that are still running the OEM brakes have also switched to braided lines so that is a moot point. Pad choice and heat dissipation are larger determinations of bite than braided lines are. You didn’t list what rear brake pad you are running, that alone could make a huge difference in bias and actual feel as well. The wrong rear pad choice will upset the balance of the car, not enough rear bite and the fronts are overworked, too much rear bite and the ABS over activates.
AP Kit discs have a larger swept area which results in less heat and better heat dissipation than OEM, the AP Kit also has less un-sprung weight than OEM, both of these are a performance benefit of the AP kit.
As far as costs, once you get past the initial investment of the AP Sprint kit:
Centric Front Rotors (2) - last 1-2 events - Cost $62.96 = $47.22 per event
Front CSG Spec C1 pads - last 5-6 events - Cost $509.18 = $93.35 per event
This averages $140.57 per event
AP Sprint Rotor Blanks (2) - 10-12 events - Cost $409.74 = $37.56 per event
Ferrodo DS1-11 Pads - 5-6 events - Cost $307.77 = $56.43 per event
This averages $93.99 per event
All prices listed above include shipping, # events they last is based on my personal experience.
There are hundreds of pads available for the AP caliper, from multiple companies in multiple compounds to suit your needs and wallet. Also, there
are 3rd party options for rotor blanks for the AP kit, Coleman Racing Products rotor blanks are even cheaper so the cost per event drops even more…
While I'm not knocking the the OEM brakes, they are good for what they are, however, they simply do not match the performance or cost benefit of the AP Sprint kit for track use.
