2020-2026+ BMW M235i Gran Coupé (F44/F74/F78) Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2020-2026+ BMW M235i Gran Coupé (F44/F74/F78) Carbon Ceramic Brake Kit — OEM-Size Replacement
The 2020-2026+ BMW M235i Gran Coupé uses a large OEM M Sport brake package for a compact AWD sedan, with 360 mm front rotors and 330 mm rear rotors on the M235i fitment listed for this page. This StopFlex OEM-size carbon-ceramic kit replaces the iron rotors with carbon-ceramic rotors, matched pads, hats, and floating hardware to cut brake dust, reduce rotating mass, and improve repeat-stop thermal stability without changing the factory brake layout.
- Built around the M235i Gran Coupé 360 mm front and 330 mm rear OEM-size rotor references, not the smaller 2 Series Gran Coupé brake packages.
- Designed for F44/F74/F78 M235i Gran Coupé fitments using the listed M Sport-size brake package, so caliper position and brake balance stay based on the factory rotor diameters.
- Carbon-ceramic rotors reduce iron brake dust on the M235i’s open wheel designs and reduce rotating unsprung mass at both axles compared with same-size cast-iron discs.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | BMW M235i Gran Coupé (F44/F74/F78) |
| Model years | 2020-2026+ |
| Front rotor reference | M235i: 360mm |
| Rear rotor reference | M235i: 330mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 15" (for the 235 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 235 mm rotor, so the minimum wheel size is 15". Wheels under 15" 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 kit fit every 2020-2026+ BMW 2 Series Gran Coupé?
No. This page is only for the BMW M235i Gran Coupé F44/F74/F78 fitment with 360 mm front rotors and 330 mm rear rotors. Confirm your trim, chassis code, and rotor diameters before ordering.
Do I need different calipers or coding?
This is an OEM-size replacement kit, so it is intended to work with the factory M235i caliper layout for the listed 360 mm front and 330 mm rear brake setup. The kit includes carbon-ceramic rotors, pads, hats, and floating hardware; it is not a caliper-conversion kit.
Will the electronic parking brake and auto-hold functions still work?
Yes, when installed on the compatible M235i Gran Coupé rear brake configuration listed for this page, the rear service brake hardware is replaced while the vehicle’s factory electronic parking brake control strategy is retained.
What should I confirm before ordering for wheel clearance?
Confirm that your car is the M235i Gran Coupé F44/F74/F78 with the listed 360 mm front and 330 mm rear rotors, and verify wheel clearance against the factory M Sport brake package. BMW’s 360 mm front brake package is associated with 18-inch-or-larger wheel clearance, but aftermarket wheel barrel shape can vary.
