Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2017-2026+ Audi Q2 / SQ2 (GA). This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2017-2026+ | Akebono OEM Audi S 6-Piston (8N) Caliper / 380mm | TTSPORT EP4 4-Piston Forged Caliper integrated with EPB / 380mm | 19" |
Fitment here is bespoke: brackets, hat offsets, and caliper mounting are engineered for your exact model and trim rather than copied across the platform. Two trims with the same chassis code can still differ in knuckles, hub geometry, and wheel ET clearance — which is why we confirm your trim first, then build the matched system of calipers, pads, rotor hats, floating hardware, and lines for it. Modified knuckles, uprights, or non-factory suspension points require review before ordering.
The 380 mm rotor sets the minimum wheel size at 19" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.
| Wheel Size (Standard) | Disc Range |
|---|---|
| 15" | 260 mm – 285 mm |
| 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 |

Why Carbon Ceramic — and Why StopFlex
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Winter & Cold-Weather Braking
A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose Street Spec.
Caliper Overview
Front Caliper
The front caliper is the Akebono OEM Audi S 6-Piston (8N) unit, a six-piston monobloc used on Audi S-line factory brake systems. Six pistons spread clamping load evenly across the pad, which keeps pedal feel firm and predictable when you're hauling the Q2 or SQ2 down from speed on a 380mm carbon-ceramic rotor.
Rear Caliper
The rear is the TTSPORT EP4 4-Piston Forged Caliper with an integrated electronic parking brake. It uses four 28mm hydraulic service pistons plus one 27mm dedicated EPB actuator piston, so your factory electric parking brake keeps working exactly as it did while the rear axle gains real thermal capacity on a 380mm rotor. The forged two-piece aluminum body weighs about 4.50 kg per caliper without pads and carries a high-temperature gloss coating.
Choose Your Rotor: Street, Track-Day, or Motorsport
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.
Heat Management Note
Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.
Get Your Fitment Confirmed
Before ordering, tell us the exact vehicle, current rotor sizes, and caliper type. Nothing goes to production until the build is confirmed against your VIN-level configuration.
FAQ
Will this kit fit my exact Q2 or SQ2 trim?
Every kit is built to your confirmed trim, not the GA platform in general. The SQ2 uses different front knuckles, hub geometry, and wheel clearance than a standard Q2, so we cut trim-specific brackets and set the rotor-hat offsets to match your car. We do not sell this as a platform-wide bolt-on. Once you confirm your model, year, and trim, we engineer the mounting to that spec.
What wheels do I need to clear the 380mm rotors?
The 380mm front rotor sets a hard minimum of 19-inch wheels. Anything under 19 inches will not clear the caliper and rotor. Spoke design matters too, not just diameter, so a deep-concave or thin-spoke 19 can still catch the caliper. Send us your wheel model when you confirm fitment and we'll check clearance before anything ships.
How do carbon ceramic brakes behave in cold winter driving?
Honestly: an untuned cold carbon-ceramic disc bites less than cold iron on the first stop. That's physics, not a fault. We've tuned both the pad compound and the disc's ceramic coating specifically for cold starts, so cold-car braking feel now comes very close to summer feel. On the coldest first stops of the day, still leave a little extra following distance until the system warms up—then it settles into consistent, fade-free response.
Does the rear electronic parking brake still work with this kit?
Yes. The TTSPORT EP4 rear caliper has a dedicated EPB actuator piston separate from its four hydraulic pistons, so your Q2 or SQ2 keeps full factory electric parking brake function. You get the OE convenience—auto-hold, hill assist—plus genuine rear-axle thermal capacity on the 380mm rotor.
