2017-2026+ Audi Q2 / SQ2 (GA) CCB Big Brake Kit — Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper Front + TTSPORT EP4 4-Piston Caliper with EPB Rear Setup
The 2017-2026+ Audi Q2 / SQ2 GA has a short wheelbase and front-heavy braking load, so repeated hard stops can overwork the factory iron setup and fill open wheels with brake dust. This StopFlex kit moves the car to 380mm carbon-ceramic rotors with a Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper up front and a TTSPORT EP4 4-Piston Caliper with EPB at the rear for higher thermal capacity, lower rotating mass, and retained parking-brake function. Each kit is built for the confirmed Q2 or SQ2 trim, with brackets, rotor-hat offsets, and caliper mounting matched to that exact car rather than treated as a generic MQB fitment.
- 380mm front and rear carbon-ceramic rotors require 19-inch or larger wheels on the Audi Q2 / SQ2 GA; wheel spoke clearance is checked before production.
- Front braking is handled by the Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper, paired with StopFlex carbon-ceramic rotors, pads, hats, hardware, and lines.
- Rear braking uses the TTSPORT EP4 4-Piston Caliper with EPB, so the Q2 / SQ2 retains electronic parking-brake operation while adding rear thermal capacity.

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 Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper gives the Q2 / SQ2 GA a six-piston front layout that spreads pad pressure across the rotor face for stronger clamping control and a firmer, more consistent pedal under heat. Its value is the OEM-derived Akebono provenance: this is a genuine Audi RS-family caliper architecture, not an unproven universal casting. StopFlex engineers the caliper mounting, bracket geometry, and 380mm rotor-hat offset around the buyer’s confirmed GA trim and wheel package.
Rear Caliper (Balance)
The TTSPORT EP4 4-Piston Caliper with EPB adds real rear-axle braking capacity instead of leaving the rear as a cosmetic match to the front upgrade. It uses four hydraulic service pistons for braking plus a dedicated EPB actuator piston, preserving the Q2 / SQ2 electronic parking-brake function.
Front & rear, engineered together: This kit is engineered as a front-and-rear system so the 380mm front carbon-ceramic rotor and six-piston Akebono caliper are matched with rear thermal capacity, rear torque contribution, and EPB retention. StopFlex sizes brackets and rotor hats for the confirmed Q2 or SQ2 trim so the car does not receive a front-only bias shift or a platform-assumed rear fitment.
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.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |

FAQ
Will this 380mm kit fit my exact Audi Q2 or SQ2 GA?
Fitment is confirmed per car, not assumed from the GA chassis name. StopFlex verifies your model year, Q2 or SQ2 trim, hub and knuckle configuration, wheel diameter, offset, and spoke clearance before producing the brackets and rotor hats.
What wheels are required for the 380mm carbon-ceramic setup?
The 380mm rotor package requires 19-inch or larger wheels. Wheel diameter alone is not enough; the Genuine Akebono OEM Audi RS 6-Piston (8N) Caliper also needs spoke clearance, so StopFlex checks wheel specs before the kit is built.
Will the electronic parking brake still work?
Yes. The rear TTSPORT EP4 4-Piston Caliper with EPB uses hydraulic service pistons for braking and a dedicated EPB actuator piston, so the Audi Q2 / SQ2 keeps factory electronic parking-brake convenience.
Why move this Q2 or SQ2 from iron brakes to carbon-ceramic?
Carbon-ceramic rotors reduce brake dust, resist heat fade better during repeated hard stops, and lower rotating mass compared with similarly sized iron hardware. On this kit, the payoff is tied to the 380mm rotor package and the front six-piston Akebono caliper rather than a stock-size replacement.
