2006-2013 BMW 3 Series / M3 (E90/E91/E92/E93) CCB Big Brake Kit — Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper Front + Genuine Brembo GT4 Rear Setup
E90/E91/E92/E93 3 Series and M3 owners usually shop this kit after repeated iron-rotor heat issues, heavy brake dust on open wheels, or the need for a larger track-capable front brake without dealer-level carbon-ceramic replacement costs. StopFlex builds this package around a 380 mm front carbon-ceramic rotor with a Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper, then matches the 355 mm rear carbon-ceramic setup to the selected Brembo V4, GT4, or GTS4 4-piston option. Each kit is engineered for the confirmed trim, not the chassis name alone, so M3 upright geometry, standard 3 Series hub offsets, and wheel ET/spoke clearance are checked before brackets and hats are finalized.
- 380 mm front carbon-ceramic rotors require 19 inch or larger wheels on the E90/E91/E92/E93 chassis; spoke clearance is verified against the GT500 6-piston caliper body.
- Front braking is handled by the exact Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper paired with StopFlex carbon-ceramic rotors, pads, hats, hardware, and lines.
- Rear 355 mm carbon-ceramic rotors are paired with the chosen Brembo V4, GT4, or GTS4 4-piston caliper package so the rear axle is not left as a stock-iron thermal bottleneck.

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.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses the Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper, giving the E90/E92 platform a six-piston fixed-caliper layout for more even pad loading and a firmer high-temperature pedal than the small factory sliding-caliper packages. Its OEM Brembo provenance matters because the caliper was engineered for a high-output production performance car, not an unbranded universal brake conversion. StopFlex pairs it with a 380 mm carbon-ceramic rotor, vehicle-specific hats, brackets, pads, hardware, and brake lines for the buyer’s confirmed BMW trim.
Rear Caliper (Balance)
The rear axle uses Brembo V4 / GT4 / GTS4 4-Piston Caliper Options on 355 mm carbon-ceramic rotors: V4 is the Genuine Brembo OEM Cadillac CTS-V 4-Piston Caliper, GT4 is the Genuine Brembo GT | M4 4-Piston Caliper, and GTS4 is the Genuine Brembo GT | S4 4-Piston Caliper. The rear package is selected and sized to support brake balance and rear-axle stability rather than simply adding front torque and leaving the rear system unchanged.
Front & rear, engineered together: A 380 mm six-piston front upgrade changes torque capacity, heat storage, and pedal response, so StopFlex engineers the 355 mm rear 4-piston package as part of the system. Matching brackets, hats, pad compounds, and hydraulic line routing front-to-rear helps avoid the front-heavy feel that can come from a standalone front big-brake conversion on an E90/E92 BMW.
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.

- Custom caliper logo
- Custom rotor hat color
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 kit fit my exact E90, E91, E92, or E93 trim?
Fitment is confirmed by exact model, year, body style, trim, and wheel data before production. A standard 328i/335i and an E90/E92/E93 M3 are not treated as the same fitment because knuckles, hub geometry, brake offsets, and wheel clearance can differ.
What wheel size do I need for the 380 mm front rotor?
The 380 mm front carbon-ceramic rotor requires 19 inch or larger wheels. Wheel diameter alone is not enough; StopFlex also checks spoke clearance against the Genuine Brembo OEM Ford Shelby GT500 Mustang 6-Piston Caliper.
Does this BMW need EPB-compatible rear calipers?
No. The E90/E91/E92/E93 3 Series and M3 use a manual cable handbrake system, so there is no factory electronic parking brake motor to integrate into the rear caliper package.
Why convert this BMW from iron brakes to carbon-ceramic?
Carbon-ceramic rotors reduce rotating and unsprung mass, cut visible brake dust, and tolerate repeated heat cycles better than standard iron rotors when the car is driven hard. On this kit, the 380 mm front and 355 mm rear rotor sizes add thermal capacity while keeping the package engineered around the confirmed BMW trim.
