Front Floating 2-Piece Slotted Brake Disc Kit – 350mm x 34mm and 350mm x 28mm
Sold as a set of 4

This high-performance front and rear brake disc kit features two-piece floating slotted rotors designed for Porsche 992.1 Carrera S and 992.2 Carrera models. Engineered as a direct replacement for factory steel brake discs, this upgrade delivers improved cooling, durability and braking performance for both road and spirited driving.

Fits:

  • Porsche 992.1 Carrera 2S 3.0L 2019-24
  • Porsche 992.1 Carrera 4S 3.0L 2019-24
  • Porsche 992.1 Carrera 2S Cabriolet 3.0L 2019-24
  • Porsche 992.1 Carrera 4S Cabriolet 3.0L 2019-24
  • Porsche 992.1 Targa 4S 3.0L 2020-24
  • Porsche 992.2 Carrera 2 3.0L 2024>>
  • Porsche 992.2 Carrera 2 3.0L Cabriolet 2024>>

Not suitable for PCCB (Porsche Ceramic Composite Brake) conversions.
Designed as a direct replacement for vehicles equipped with 350mm steel brake discs, including centre-lock wheel configurations.

Each assembly consists of a precision-machined aluminium hat paired with a high-carbon cast iron rotor ring, providing optimal heat management and reduced unsprung weight.

What This Brake Disc Kit Does

Brake discs convert kinetic energy into heat during braking. This upgraded system improves heat dissipation and braking consistency under load.

It helps:

• Improve braking performance and consistency
• Enhance heat dissipation during repeated braking
• Reduce brake fade under high temperatures
• Improve pedal feel and braking response
• Increase durability compared to standard discs

Advanced Two-Piece Floating Design

The floating disc construction allows the rotor ring to expand independently from the hat under heat, reducing stress and preventing distortion.

Key benefits include:

• Reduced risk of warping under heavy braking
• Improved thermal stability
• Minimized vibration and brake judder
• Enhanced performance during repeated braking cycles

High-Performance Materials & Engineering

CM-250 High Carbon Alloy Cast Iron Rotors
Manufactured using a formulated high carbon alloy for increased strength, durability and heat resistance.

72 Cooling Vanes
Internal vane design maximises airflow through the disc, significantly improving cooling efficiency.

Heat-Treated Rotor Rings
Stress-relieved during manufacturing to prevent deformation and vibration under extreme conditions.

CNC Machined 6061-T6 Aluminium Hats
Lightweight yet strong, precision machined and hard anodised for corrosion resistance and durability.

Slotted Disc Surface
Improves pad bite, helps remove gases and debris, and enhances braking performance in all conditions.

Key Specifications

• Disc Type: 2-piece floating slotted
• Disc Size: 350mm x 34mm
• Cooling: 72 vane internal design
• Construction: High carbon iron rotor with aluminium hat

Why Upgrade Your Porsche 992 Brake Discs

Factory brake discs are designed for general road use. Under performance driving, they can suffer from heat build-up, fade and reduced efficiency.

Upgrading to a two-piece floating system provides:

• Better cooling and heat management
• Increased resistance to brake fade
• Reduced unsprung weight
• Improved braking consistency under load
• Longer service life under demanding conditions
