## Description

These Girodisc D1-156 front replacement braking surfaces (410 × 36 mm) allow you to replace the braking surfaces on your GIRODISC bowl-style rotors for the Porsche 911 (991.2) Carrera with carbon-ceramic rotors (2015+), Porsche 911 (992) Carrera GTS (2019+), Porsche 911 (992.1) Carrera S, 4S, and GTS with carbon-ceramic rotors (2015+), Porsche 911 (991) Turbo and Turbo S with carbon-ceramic rotors (2013–2019), Porsche 911 (992) turbo (2019+), Porsche Cayman (981) GT4 with carbon-ceramic rotors (2015–2016), Porsche 718 (982) Cayman GT4, Boxster Spyder with carbon-ceramic rotors (2019–2023), while retaining compatible brake calipers after inspection. These cast-iron tracks maintain the floating mounting’s functionality and facilitate maintenance of a braking system subjected to repeated stress. Sold in pairs, without brake calipers.
The curved internal cooling fins channel air through the rotor to dissipate heat during repeated braking. The floating mounting limits stresses caused by thermal expansion differences between the rotor and the caliper housing and helps the rotor center itself between the brake pads, maintaining consistent contact even when hot.
New brake pads must be installed with new rotors or brake discs. Their shape and compound must match the mounting configuration, cast material, and intended use; follow the specific requirements for this part number and perform the prescribed break-in procedure.

Brake Pads and Brake Systems for Compatible Vehicles
Choose brake pads whose shape is compatible with the calipers and the D1-156 track, and whose compound is suitable for sport driving or track use. The Endless, Pagid Racing, or Ferodo Racing ranges may be considered after verifying the appropriate part number.
For intensive use, we recommend compatible aviation-grade hoses and a high-performance brake fluid that meets the vehicle’s specifications, along with proper bleeding and fluid replacement. This recommendation complements the mounting, which is compatible with the original hydraulic system.
Maintenance of the Girodisc mounting on compatible vehicles
When worn, replace the pads with the part number compatible with your existing rotors. Reusing a rotor for up to three pad replacements is subject to inspection of its condition, its mounting components, and the mounting instructions; this number does not constitute a guaranteed service life. Use a new mounting component each time you replace the pads.
FAQ — Girodisc D1-156 for compatible vehicles
What are the sizes of the D1-156 tracks for my vehicle? The part number shown measures 410 × 36 mm and mounts to the front axle. The track height, mounting bracket, and cups must also be compatible with the mounting.
Is the product sold in pairs? Yes. It includes a left and a right component for the same axle. The brake shoes are not included.
Do I need to replace my vehicle’s brake pads?Yes. Always install new brake pads with new rotors or new braking surfaces. Use a compound suitable for cast iron and your intended use. Use the GT3/Turbo (991/992) brake pad shape intended for cast iron rotors, with a reduced sweep height.
How do I identify the left and right sides? Girodisc rotors come with a label attached to each rotor: LEFT for the left side and RIGHT for the right side, as viewed from the direction of travel. On a left-hand-drive vehicle, “LEFT” corresponds to the driver’s side and “RIGHT” to the passenger side. Follow these labels and the instructions. On models with curved internal fins, the rolling direction depends on this internal ventilation; the surface grooves alone are not sufficient to determine the side.
How do I break in this mounting on my vehicle? Follow the Girodisc procedure and the brake pad manufacturer’s instructions to build up an even transfer ply. The PDF documents below detail installation and break-in.
PDF Documents for Mounting and Break-in
We have included two PDF documents below: an instruction manual for installing and running in the discs, and an instruction manual for installing new tracks on existing bowls. Consult the document that applies to your specific task before you begin.
