The new caliper is a monoblock just like the OEM rear caliper. The new caliper is made to accommodate the bigger and thicker CCM rotor. If you didn’t know all Brembo CCM spec calipers are painted yellow. So when you see a Porshe or other make with yellow calipers, you find CCM rotors under them!
Notice the CCM caliper has a forging that more tightly follows the pistons for less weight.
You can see some of the differences in contours here. The little bracket on top of the CCM caliper is for a wear sensor the US market cars don’t have. The brake pads are hung in much the same way as the stock caliper.
The calipers are installed on the car, the bolts torqued down, pads installed and lines and sensors hooked up. The system was bled with the Endless RF-650 fluid, first with a vacuum bleeder to flush the system of the old fluid, then hand bled to finish the bleeding.
You can see how the modified backing plate now clears the thicker rotor and how the internal vanes now have direct access to cooling air not shrouded by the dust shield.
The rear brakes look pretty damn sweet!

As always, great content. Thanks for all the info on parts I can only dream of having. I feel I can’t even afford to read the article. (I’m one of your IG followers and long time SCC subscriber)
I personally don’t think they are cost-effective but they sure are cool!
did you guys weigh the rotors? kinda curious about the actual weight difference over just the generic 30% lighter…
Yes on the last page, we saved 40.4 lbs over the OEM brake system.
With such a difference in rotor diameter and a greater difference front vs rear, does the brake bias change at all? 40lbs of rotating and unsprung mass saved is crazy. Makes the price seem realistic if you’re chasing the absolute best feeling possible.
No, it doesn’t change, it’s factory-engineered.
I had always been told that larger rotors on a street car are actually detrimental, since it takes longer for them to reach optimal temperature for good braking. Does the same apply to carbon ceramic rotors?
That’s not true at all. Bigger brakes allow you to run streetable less aggressive pads on the track. Race pads will literally eat rotors on the street in a few hundred miles. Big brakes allow true dual-purpose use. More brake power is typically also easier to modulate.
Just out of curiosity, can you recommend any places to source these on the used Japanese market like you guys did?
I used google to find a set and had a Japanese friend ship them to me.
There’s a website called, Croooober.com, that you might want to check out.
