2017-2026+ Porsche 718 Boxster (982) Carbon Ceramic Big Brake Kit — Brembo Porsche 911 GT3 6-Piston

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.

Front Caliper

Front clamping is handled by the Brembo OEM Porsche 911 GT3 6-Piston Caliper. The six opposed pistons give consistent pad loading across the 410mm rotor, so pedal feel stays firm through repeated hard stops.

Rear Caliper

The rear uses the Brembo OEM Porsche 911 GT3 4-Piston Caliper on a 390mm rotor, adding rear thermal capacity to balance the larger front and keep brake bias predictable under heat.

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.
