Stoptech C43 Competition Front BBK Review
Rotor rings are cheaper to replace by a large margin, pad material is considerably thicker and shares the same backing as the Essex CP8350 and Wilwood superlite calipers. A nice 50mm depth lasts a long time. The weight is one of the idealogical factors but Im not scientist enough to know if thats going to be detrimental to a long session for heat capacity for a typical driver.

I know im quite satisfied with the Trophies and wont be going out of my way to change them out for something else. But for a new buyer, seems like worth looking into certainly.

Thicker pad material is good and cheaper rings is great, but seemed like the Trophy's kind of hit the sweet spot with reduced caliper weight and increased stiffness and durability, at least over the base st40 caliper. Wonder if this new caliper accel's further again in both arena's, or if it sacrifices some aspects of durability for the sake of lightness. The cost seems right in line with the Trophies. Typically a company adds a option to their line up to fit another facet, rather then sacrifice a current for a new, but maybe this makes the trophy absolute in this case

But for a new buyer, seems like worth looking into certainly.I feel like any other differences besides price/wear of consumables between the trophy and c43 would be nitpicking or not felt by 90% of people with the remaining 10% being those that push hard in w2w or long 30 minute sessions testing the thermal capacity of the kit that the trophy kit probably has the edge in based on mass. I too have the trophy kit and dont plan on switching but it makes me happy that big companies are still making high end parts for the S and Im keeping that new rear bbk in my peripherals for when people start posting reviews.
Does anyone have a comparison of what the SR33 / SR34 pads that come with this kit are like? When you start doing the math it seems like a no-brainer to go with this kit over the ST40 given that rotor rings are less than half the price and replacement pads are also something like 30% cheaper. You're throwing the pads that come with the ST40 kit in the trash so you need to add that to the purchase price when comparing them.
Also, how different is wheel clearance?
edit: The SR33 pads are great, they make the DTC60 in stock calipers feel like a toy. They are significantly less streetable in terms of noise and the rise in friction from being warmed up is substantial

Well, I did the legwork myself today -- the results are... not great.
I made this C43 template by scaling the small one Evasive has on their website and verifying measurements by hand after printing. This is probably where people screw up using the printable templates. I am not linking it inline with the post because it is xbox huge.

So..... what do you get when you lay the ST40 caliper template ontop of the C43 caliper template?

Overall width of the caliper is not the issue, the difference is about 1.2mm in that respect for spoke clearance, but how the caliper begins 105mm from wheel center compared to 114mm from center. I laid the ST40 template in my 17x10 +55 SA72R and found it is fine clearance wise. The C43 template clears by something like a millimeter. Probably need to run a 2-3mm spacer to be safe, but we will see, I am going to order them anyway since the wheels clear the fenders by a country mile.

RSG test fit the 17x10 SA72R on a car with the C43. Was able to confirm it does clear but it looks really tight.
Also, Stoptech sent me the official fitment template, I've attached it to this post. VERIFY YOU PRINTED CORRECTLY BY MEASURING AN X AND A Y DIMENSION WITH CALIPERS / RULER
