Which diveplanes are on your car? Did you notice more front-end grip or was it more cosmetic?
That isn't mine, I believe it belongs to someone at Rockstar Garage.

Street version is available. Also, the race kit can be easily converted to a street kit with the conical hardware pin kit. Brad at Stoptech was mega helpful when I was putting my kit together.
Here are the part numbers that will be of great help;
309.80210 - StopTech Sport Pad Sport Pad - Standard in SPORT 333.8021.21.0 - StopTech SR33 Race Friction Race Pad - Standard in RACE STP89.000.0021 - Pin Kit, RACE STP89.000.0015 - Pin Kit, Street 28.001.1118.CT.87 - 309x32 (12.19x1.25) Pillar Bi-Slot Replacement rotor WITH race drive pins 28.001.1118.CT.99 - 309x32 (12.19x1.25) Pillar Bi-Slot Replacement rotor WITH street drive pins
I'm currently running the race kit on my car. The SR33 pads were really noisy, so I switched out for winmax W4s. Theyre still quiet noisy for street driving but I dont mind as my car isn't a daily driver anymore. I love that the calipers take a really common pad size.I will probably switch out for for Project Mu's Club Racers (which are less noisy in comparison to the SR33 and W4, after a few track days.
The SR33 are definitely not street friendly, but they work ungodly well. I have about 20hr on my kit right now, the pads are roughly half way through the material. I was doing 6-8hr per set of DTC60s on the OEM calipers prior, along with experiencing extreme pad fade.
When I received my kit, I got black anodized rotor hats. I was just wondering if my hats we're the same part number as yours. Also do your rotor hats have the aero fins for additional cooling? Mine are just blocks and do not have the cooling fins.
Here is a good pic of what the cooling fins look like on stoptech rotor hats.
Hello. Is that the part number for the rotor hat that your kit came with? When cross referencing it is for a BMW with a C43 kit. If that is accurate we may have found a potential solution for the lack of s2k rotor hats from StopTech right now...

Thanks and I look forward to your response.

Not the OP you quoted, but the part # for the hats on my kit ended in 94C5 instead of 9415.
Hey. I have a c43 bbk on my s2k, and I was wondering what street option pads people are using? The race pads that come with the kit are way too noisy on a daily use application. Lol.
the stoptech pad 309 that comes with the street kit are completely silent
they are chamfered on the leading edges, try adding a little chamfer to the leading edge of the pads and it may keep sound down
