2024-2026+ BMW i7 M70 (G70) Carbon Ceramic Brake Kit — OEM-Size Replacement
The G70 BMW i7 M70 puts 650 hp and more than 6,000 lb of EV mass through a brake package that sees high thermal load in repeated highway-speed stops. This StopFlex OEM-size replacement kit keeps the i7 M70 rotor format—395mm front and 398mm rear—while replacing the iron friction rings with carbon-ceramic rotors, matched pads, hats, and floating hardware for lower dust, reduced rotating mass, and repeatable heat behavior without changing the factory brake layout.
- Built for the 2024-2026+ BMW i7 M70 (G70) with the 395mm front / 398mm rear rotor setup listed for this page.
- Carbon-ceramic friction rings reduce brake dust on the i7 M70’s large open-face wheels compared with the factory iron rotor and pad wear pattern.
- OEM-size hats and floating hardware are supplied with the rotors so the kit matches the factory caliper position instead of converting the car to a larger brake package.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | BMW i7 M70 (G70) |
| Model years | 2024-2026+ |
| Front rotor reference | i7 M70: 395mm |
| Rear rotor reference | i7 M70: 398mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 20" (for the 398 mm rotor) |
For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
This setup uses a 398 mm rotor, so the minimum wheel size is 20". Wheels under 20" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
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.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
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 fit every 2024-2026+ BMW i7?
No. This page is limited to the BMW i7 M70 (G70) using the 395mm front and 398mm rear rotor sizes listed here. Do not order it for eDrive50, xDrive60, or any G70 with a different brake package unless StopFlex confirms the rotor dimensions and caliper fitment.
Does the rear electronic parking brake and auto-hold system still work?
The kit is designed as an OEM-size replacement for the i7 M70 rear brake package, so the rear hats and hardware are built around the factory rear brake architecture. Before production, confirm your VIN, rear rotor size, and parking-brake configuration so the supplied rear components match the car.
Why switch an i7 M70 from iron rotors to carbon ceramic?
On a 6,000-lb-class electric sedan, rotor temperature rises quickly during repeated deceleration even with regenerative braking. Carbon-ceramic rotors handle heat with less fade, produce much less visible dust, and remove rotating mass at all four corners while keeping the factory 395mm/398mm sizing.
Is this for street use, track use, or both?
It is an OEM-size replacement kit for i7 M70 owners who want cleaner wheels, lower unsprung mass, and more stable repeat-stop performance without changing calipers. If the car will see track days, confirm wheel clearance, tire setup, and pad choice with StopFlex before ordering.
