6‑Piston Front Caliper Pair for Porsche 991 Carrera – 9P1615123B / 9P1615124B / 9P1615123C / 9P1615124C

Upgrade the front axle of your Porsche or custom big brake project with genuine Porsche 991 Carrera red 6-piston front calipers, developed by Brembo for the 991-generation 911 and shared across multiple modern Porsche sports car platforms.

These calipers are designed for the 350 mm × 34 mm front rotor package found on 991.2 Carrera S / 4S / GTS models, delivering strong and consistent braking performance with a compact body that also works excellently for front-axle carbon ceramic conversions.

Key Features

• Genuine Porsche/Brembo 6-piston aluminum fixed calipers for 991-series Carrera models.
• Factory red finish with white "PORSCHE" logo – ideal for premium street and track builds.
• Engineered around 350×34 mm vented front discs for high thermal capacity and firm pedal feel.
• Compact caliper body with large pad volume – a strong base for front CCB or big brake retrofit kits on heavier platforms.
• New OEM units, not rebuilt or refinished, supplied without pads.

OEM Part Numbers (Red Iron Caliper Family)

Porsche parts listings and dismantler catalogs associate the following references with this 6-piston front caliper family:

• 9P1615123B / 9P1615124B – front left / right 6-piston calipers for iron brake setup.
• 9P1615123C / 9P1615124C – later superseding numbers for the same calipers.

Related PCCB variants, for reference only and not included in this listing:

• 9P1615123S / 9P1615124S – yellow PCCB 6-piston front calipers for the 410×32 mm ceramic system on 991.2 and 992 Carrera / Turbo applications.
• 9P1615123K / 9P1615124K – earlier PCCB references listed as compatible with the same ceramic setup.

Porsche Applications

• Porsche 911 991 / 991.2 Carrera S, Carrera 4S, Carrera GTS – front axle, 350×34 mm iron rotor package.
• Porsche 718 Cayman (982) – front axle on higher-spec variants and related performance brake configurations.
• Also used as an upgrade front brake package on various 911 Carrera derivatives with the large 6-piston front system.

Because the mounting geometry is shared with other 991/982 platforms, these calipers are widely used in retrofit and swap projects on earlier Porsche models and other brands using custom brackets and rotors.

Rotor Size & Compatibility

• Originally designed for 350 mm × 34 mm front discs.
• Compatible with multiple aftermarket rotor options in the same 350×34 mm size.
• Can be adapted to 380×34 mm front discs in custom kits with appropriate brackets and pad annulus selection.

Ideal for Retrofit & CCB Projects

Thanks to the 6-piston layout and compact shape, this caliper is an excellent front-axle solution for:

• OEM-style upgrades on 991/718, including iron-to-CCB or higher-performance two-piece rotor conversions.
• Big brake kits for heavy luxury sedans and SUVs such as Rolls-Royce, Bentley, and Mercedes-AMG G-Class.
• Custom BBK projects on non-Porsche platforms using bespoke hats, rotors, brackets, and brake lines.

For non-Porsche vehicles, we recommend using these calipers only as part of a fully engineered kit with matched rotors, hats, brackets, brake lines, and proper brake-bias calculations.

What’s Included

• 1 × front left 6-piston caliper – Porsche ref. 9P1615123B / 9P1615123C or equivalent superseding number, red finish.
• 1 × front right 6-piston caliper – Porsche ref. 9P1615124B / 9P1615124C or equivalent superseding number, red finish.
• Factory hard lines and pad retaining hardware pre-installed.

Not included: brake pads, rotors, brackets for non-Porsche platforms, and brake lines.

Notes

• For 991/718 applications, please confirm fitment by VIN and existing rotor size before ordering.
• For Rolls-Royce, Bentley, G-Class, and other retrofit projects, these calipers should be used as part of a complete engineered brake kit tailored to the vehicle.
• Sold as a matched left/right pair; individual calipers may be available on request.
