We were now able to remove the two main and one secondary radial caliper mounting bolts and big rotor adaptor spacer.
The rotor and caliper can now be removed from the knuckle. Normally when installing big brakes, we remove the dust shield. However the R35 front dust shield is minimal, doesn’t interfere with cooling airflow, and protects the sensor line, brake lines, and tie rod ends from heat. Since the CCM brakes radiate more heat, we thought it would be a good idea to leave it in place. We did have to bend it slightly as it lightly rubbed the much thicker rotor.
You can see how much bigger the CCM rotor is compared to the already much bigger Brembo big 405mm rotor. Also, note how wide the annulus is on the CCM rotor compared to the wide annulus Brembo performance big diameter iron rotor! When compared to the OEM 380 mm rotor the swept area of the CCM rotor is over 2x greater!
The 38mm thick CCM rotor is much thicker than the thicker Brembo big rotor 34mm thick rotor. OEM rotors range from 32 to 34 mm thick.

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.
