1999-2002 Nissan Skyline GT-R (R34) CCB Big Brake Kit — Genuine Brembo GT6 Front + Genuine Brembo GT4 Rear Setup
The R34 Skyline GT-R is heavy enough and fast enough that repeated high-speed braking can overwork conventional iron hardware, especially on cars used for track days, canyon driving, or sustained high-power street builds. This StopFlex Kit Upgrade pairs 380 mm front and rear carbon-ceramic rotors with Brembo V6 / GT6 / GTS6 6-piston front options and Brembo V4 / GT4 / GTS4 4-piston rear options for higher thermal capacity, lower brake dust, and reduced rotating mass. Each kit is built around the confirmed BNR34 GT-R configuration, including bracket geometry, rotor-hat offset, caliper position, brake lines, and wheel-clearance requirements.
- 380 mm carbon-ceramic rotors are used front and rear, so the R34 GT-R requires 19 inch or larger wheels and spoke clearance must be checked before production.
- Front choices are V6, GT6, or GTS6 Genuine Brembo 6-piston calipers; every front option is paired with a 380 mm rotor for this kit.
- Rear choices are V4, GT4, or GTS4 Genuine Brembo 4-piston calipers on 380 mm rotors, allowing the rear axle to be matched to the upgraded front instead of left as an afterthought.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 380 mm front rotor, so the minimum wheel size is 19". Wheels under 19" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |

| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |
Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses Brembo V6 / GT6 / GTS6 6-Piston Caliper Options, giving the R34 GT-R a stiff 6-piston clamping package for consistent pad pressure and pedal response with the 380 mm rotor. The buyer chooses among V6 = Genuine Brembo OEM Cadillac CTS-V 6-Piston Caliper, GT6 = Genuine Brembo GT | M6 6-Piston Caliper, or GTS6 = Genuine Brembo GT | S6 6-Piston Caliper, and each front option is engineered around the same 380 mm carbon-ceramic rotor. These are genuine Brembo caliper families, not generic castings, and the final mounting geometry is matched to the confirmed car.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options on 380 mm carbon-ceramic rotors to support rear braking contribution without overpowering the front axle. Rear choices are V4 = Genuine Brembo OEM Cadillac CTS-V 4-Piston Caliper, GT4 = Genuine Brembo GT | M4 4-Piston Caliper, or GTS4 = Genuine Brembo GT | S4 4-Piston Caliper.
Front & rear, engineered together: The front and rear packages are engineered together so piston area, rotor diameter, pad selection, hat offset, and caliper location work as a system on the BNR34 chassis. That matters on an AWD GT-R because a front-only mismatch can change pedal travel, ABS behavior, and rear stability during trail braking or repeated high-speed stops.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

FAQ
Will this 380 mm kit fit my exact R34 Skyline GT-R?
Fitment is confirmed per car before production. StopFlex does not treat every R34 Skyline as the same; the brackets, rotor-hat offsets, caliper mounting, line routing, and wheel-clearance checks are matched to the customer’s confirmed BNR34 GT-R configuration.
What wheel size do I need for the 380 mm carbon-ceramic rotors?
This kit requires 19 inch or larger wheels because the front and rear rotors are 380 mm. Wheel diameter alone is not enough; spoke shape, barrel profile, wheel offset, and caliper face clearance must also be checked against the selected Brembo V6 / GT6 / GTS6 front caliper.
Does the R34 GT-R have an EPB that must be retained?
No. The 1999-2002 R34 Skyline GT-R uses a manual cable handbrake, not a factory electronic parking brake, so there is no EPB motor or auto-hold function to integrate with the rear caliper package.
Why choose carbon-ceramic instead of a large iron big-brake kit?
Carbon-ceramic rotors reduce rotating and unsprung mass compared with equivalent iron rotors, produce less visible brake dust, and tolerate repeated heat cycles better when properly matched with the supplied pads. On a GT-R running open 19 inch wheels or repeated track sessions, those gains affect steering response, wheel cleanliness, and fade resistance.
