Case summary
The Nissan R35 GT-R utilizes an incredibly strong factory brake foundation. For this specific build, replacing the calipers was unnecessary. The objective was to improve thermal consistency during repeated hard braking while enhancing the wheel-view appearance behind the spokes. The solution retained the OEM Brembo multi-piston calipers while upgrading the heavy iron discs to StopFlex carbon-ceramic rotors.

What usually becomes the limit on a Nissan R35 GT-R
The R35 GT-R is heavy, weighing approximately 1,740 kg (3,836 lbs), and carries massive twin-turbo V6 power. The factory 6-piston front and 4-piston rear Brembo calipers provide immense clamping force. The primary bottleneck is not stopping power, but heat capacity.
Factory iron rotors handle street driving without issue. However, during fast canyon runs or track use, heat stacks rapidly in the iron rings. This leads to brake fade and an inconsistent pedal. Visually, standard iron rotors produce heavy, abrasive black dust and develop a dark, worn look over time.
Upgrade recommendation (Nissan R35 GT-R-specific)
For an R35 GT-R originally equipped with steel rotors, the most efficient upgrade path is retaining the factory Brembo calipers. Swapping to StopFlex carbon-ceramic rotors and matched pads directly addresses heat saturation, reduces unsprung mass, and immediately brightens the wheel-view aesthetic.
What we changed and why
- Retained OEM Calipers: Kept the factory 6-piston front and 4-piston rear Brembo units. They offer excellent structural rigidity. There is no engineering requirement to replace them for this specific thermal upgrade.
- Rotors: Installed StopFlex carbon-ceramic rotors. This replaces the heavy, heat-soaking iron discs, significantly raising the thermal ceiling and pulling rotating unsprung mass off the hubs.
- Friction Material: Installed CCB-specific brake pads. The compound was matched to the owner's specific street and canyon driving profile for optimal cold bite and operating temperature range.
OEM steel vs StopFlex carbon-ceramic (case view)
| Metric | OEM Steel Setup | StopFlex CCB Upgrade |
|---|---|---|
| Thermal capacity | Street limits; prone to heat soak under heavy load | Exceptional; maintains friction targets at extreme temperatures |
| Repeated hard braking | Pedal feel drifts as heat builds | Highly stable and repeatable |
| Rotating / unsprung mass | Higher baseline weight | Significantly lower, aiding steering response |
| Wheel-view appearance | Produces heavy dust; darkens over time | Cleaner, premium technical visual presence; virtually dust-free |
| Disc surface finish | Standard iron grain | StopFlex proprietary coating formula improves smoothness and reflectivity (final look depends on wheel design, lighting, and photo exposure) |
| Performance variables | - | Total performance still depends on pads, fluid age, tires, and driver inputs. |

FAQ
Can I keep the OEM front calipers on an R35 GT-R?
Yes. For R35s originally equipped with steel rotors, the first and most effective upgrade target is the rotor material and pad compound, not a caliper swap. The factory Brembo calipers are highly capable and rigid.
Is this upgrade path for OEM steel-rotor R35 cars only?
Yes. If your vehicle is already equipped with factory carbon-ceramic brakes (such as specific Nismo trims), you must use a direct-replacement CCB path engineered for that specific factory hardware package.
Will carbon-ceramic rotors alone fix brake fade?
No single component eliminates fade entirely. While high-capacity carbon-ceramic rotors drastically raise the thermal ceiling, the overall fade resistance still depends heavily on brake fluid condition, proper pad compound, cooling airflow, and driver inputs.
