Ill chime in here:
Ive had both the ST40 and was offered to test the C43 kit. Zero performance benefit C43 vs ST40
C43 is LOUD. Like distractingly so. Removed C43 and went back to my ST40 which is in my opinion the best brake kit you can buy for the S2K.
FWIW my ST40 kit has nearly 400 (that is not a typo) track days on it. Ive changed rotors 3x. If thats not a winning consumable ratio youre asking too much.

@anorexicpoodle just curious is that with or without brake ducting? Roughly how many pad changes per set of rotor rings are you doing?
I also have the ST40/ST22 setup with no ducting and I am still on the first set of rings and pads after roughly 10 track days. I will need to swap front pads soonish but everything else looks good still.

@Hondahero10 No ducting, stock rear brakes.
Im getting about 25 days on pads (approx 1 year) and about 80-100 on rotors.

@anorexicpoodle nice, major usage! Seems like you've extending both front and rear life significantly and no form of rebuild on either front or rear?

Jakob pretty much said it - it really depends on how you're using the car and what you prioritize but all else equal either stoptech kit will have more thermal mass and be able to shed excess heat better while also using substantially larger pads (in terms of volume). If you're looking to reduce consumables cost as much as possible the C43 has been proven to be an excellent option but if the car is mostly street driven and you're looking to reduce the frequency in which you have to replace parts then the ST40 is likely going to be worth the weight penalty for you. The difference between the standard ST40 and the trophy kit is a bit of extra machining to take an additional ~1lb out of each caliper without reducing stiffness and they are hard anodized instead of powder coated for greater finish durability when subjected to extremely high heat. I believe we have all options in stock and ready to ship if you're interested.
