Transform your braking performance with these genuine OEM Porsche Akebono 10-piston front ceramic brake calipers (part numbers 9Y0615123AS / 9Y0615124AS), engineered specifically for 440×40 mm front discs. Developed for Porsche high-performance ceramic brake applications, these ultra-high-performance calipers deliver exceptional stopping power, outstanding thermal stability, and lightweight construction for maximum confidence on both road and track. The advanced 10-piston Akebono design provides strong and even pad pressure distribution, helping improve pedal feel, braking consistency, and fade resistance under repeated high-load use.

OEM-grade performance & fitment

Specifically engineered for 440 mm front ceramic brake discs (440×40 mm), making them an excellent solution for Porsche ceramic brake systems and premium big brake conversions.
The 10-piston Akebono layout is designed to provide highly balanced clamping force across a large pad surface, improving initial bite, pedal modulation, and high-speed braking stability.
OEM Porsche engineering ensures premium manufacturing quality, proper thermal control, and dependable performance in demanding street, autobahn, and track-day conditions.
Lightweight caliper construction helps reduce unnecessary mass while maintaining the rigidity required for precise and repeatable braking performance.
Compatible fitment always depends on the correct rotor size, disc offset, caliper carrier/adapters, brake lines, and wheel clearance for the target vehicle.

Porsche and performance-platform compatibility

White calipers are specified as:

9Y0615123AS – left
9Y0615124AS – right

Yellow calipers are specified as:

9Y0615123AC – left
9Y0615124AC – right

Acid Green calipers are specified as:

9Y0615123AD – left
9Y0615124AD – right

These calipers are best suited for:

Porsche 440 mm front ceramic brake applications
OEM Porsche ceramic brake replacements
High-end brake conversions using Porsche Akebono calipers with the correct 440 mm rotor setup
Custom premium performance builds requiring OEM Porsche braking components and large-diameter front brake systems

With the correct mounting solution, disc offset, and rotor hardware, they may also be considered for selected VAG, Porsche-based, and exotic performance chassis in custom conversion projects. As with all brake conversions, vehicle compatibility must be confirmed by platform, knuckle mounting pattern, rotor offset, hat/backbone dimensions, and wheel spoke clearance before installation.

Customization options

Color and logo customization is available on request at additional cost, including custom caliper finishes and model-specific branding for OEM+ or bespoke builds.
Sold as a complete front caliper set (left + right) for 440 mm applications.
Ideal for use with 440 mm ceramic rotors or other properly engineered high-performance disc setups designed around these calipers.
A strong choice for customers building track-focused cars, high-performance street cars, luxury performance SUVs, and show vehicles where OEM heritage, visual impact, and braking performance all matter.

These Porsche Akebono 10-piston calipers are the perfect solution for enthusiasts and builders looking for factory-level engineering, premium appearance, and serious braking capability in one package.

Rotor & Wheel Fitment Guide

Minimum wheel diameter guidance by rotor size. Always validate final fitment using a physical template and measured clearances.

Rotor Size (Diameter x Thickness)	Minimum Wheel Size	Technical Fitment Notes
280mm - 300mm × 20/28mm	15-inch	The smallest workable upgrade size, and only with compact low-profile callipers. Requires at least 340mm of clear inner wheel barrel. Steel systems only - carbon ceramic is not produced in this diameter range.
310mm × 22mm	16-inch	Fits most 16-inch wheels. Installation on 15-inch wheels is possible only with specific low-profile callipers and is not generally recommended.
330mm × 28mm	17-inch	Standard entry-level size for performance brake upgrades. Fits comfortably within most 17-inch alloy wheels.
345mm - 356mm × 32mm	18-inch	Common mid-range size. Requires 18-inch wheels with standard barrel clearance.
380mm × 32/34mm	19-inch	The industry standard for Carbon Ceramic (CCB) and heavy-duty steel systems. Fits most 19-inch wheels; verify spoke clearance for wider callipers.
390mm × 36mm	19-inch (Tight Fit)	Fits 19-inch wheels with high-clearance barrels (flat inner bed). 20-inch wheels are recommended to ensure adequate air gap for cooling.
400mm - 405mm × 36/38mm	20-inch	Requires 20-inch wheels. Ensure the wheel barrel does not taper significantly near the mounting face.
410mm - 420mm × 38/40mm	21-inch	Standard fitment for 21-inch wheels. Can fit select 20-inch motorsport wheels with specialised flat barrel profiles (template verification required).
440mm × 40/42mm	21-inch (Minimum)	Extreme fitment. 21-inch is the absolute minimum requirement. 22-inch wheels are strongly advised for safe operating clearance and heat dissipation.

Essential Clearance Requirements

To ensure safety and prevent damage to components, please observe the following industry-standard tolerances when measuring your wheels:

Radial Clearance (Barrel): A minimum gap of 3mm is required between the top of the calliper and the inner wheel barrel to account for heat expansion and wheel deflection under load.
Axial Clearance (Spokes): Ensure a minimum of 3mm clearance between the face of the calliper and the rear of the wheel spokes.
Balance Weights: Ensure wheel balancing weights are positioned so they do not foul the brake calliper. We recommend placing weights outboard of the calliper zone for tighter fitments.

Important Fitment Disclaimer

The wheel sizes listed above represent minimum technical requirements based on standard barrel profiles. Due to significant variation in alloy wheel designs, particularly spoke curvature (X-factor) and inner barrel contours, meeting nominal diameter alone does not guarantee compatibility.

We strongly recommend verifying clearance instrumentally using printable fitment templates rather than relying only on visual estimates or stated wheel specifications. Please ensure at least 3mm clearance in all directions to account for thermal expansion and dynamic wheel deflection.
