Check fitment for your specific vehicle, including model, year, brake system and wheel or caliper clearance, before ordering.
What This Product Does
The two-piece construction separates the braking ring from the bell, helping the assembly manage repeated thermal cycles. Internal ventilation and a track-focused slot pattern support consistent contact between the disc and brake pad during circuit driving.
Functions
- Renews both front brake discs as a matched axle set
- Uses internal vanes to channel cooling air through each disc
- Provides slotted friction surfaces for pad contact and gas evacuation
- Directly replaces the relevant original disc assemblies
- Supports braking systems exposed to repeated high-temperature use
Technical Details
- Manufacturer: Brembo
- Reference: 103.9020E
- Contents: two front brake disc assemblies
- Disc dimensions: 380 x 34mm
- Construction: two-piece, internally ventilated and slotted
- Cooling design: 72 vanes with a reduced air gap
- Slot layout differs from the standard GT eight-slot pattern
- Supplied without a homologation fiche
- Diagram reference: 99735140991; grey cast-iron brake applications also reference 997.341.901.00
Symptoms of Fault
- Vibration or judder through the pedal or steering under braking
- Visible heat marks, surface cracking or excessive disc wear
- Reduced consistency after repeated heavy braking
- Squealing, scraping or other abnormal brake noise
- Uneven brake-pad wear or glazing
- A longer or inconsistent pedal after hard circuit use
Why Replacement Matters
Brake discs subjected to frequent track use can develop wear, heat damage or friction deposits that affect pedal consistency and pad contact. Replacing worn components helps restore correct braking-system operation. Inspect the pads, calipers, fluid and associated hardware at the same time, and follow the recommended bedding-in procedure after installation.
FAQs
- Does this set include both front discs?
Yes. It contains two brake disc assemblies for the front axle. - What fluid should be used for track driving?
Use brake fluid with a specification appropriate for the vehicle and intended operating temperatures. Replace aged fluid before demanding use. - Will these discs clear my wheels?
Confirm the existing caliper, wheel and brake-system specification before installation. - Should the brake pads be inspected?
Yes. Check pad condition, compound compatibility, wear pattern and remaining thickness when changing the discs. - Is bedding-in required?
Follow the disc and pad manufacturers’ bedding procedure to establish an even friction layer.

Push your Porsche to the limit with Brembo Track Day (2pcs) Disc Brake Kits from Design911 - precision-engineered for high-performance driving and motorsport use. These two-piece discs combine race-proven materials, lightweight design, and superior heat management, delivering exceptional stopping power and control under extreme conditions.
What They Are & What They
Do
Brembo Track Day (2pcs) Discs are high-performance,
two-piece brake rotors designed for track-focused Porsche drivers. The
floating rotor and lightweight alloy bell construction reduce unsprung mass and
improve heat dissipation, ensuring consistent performance and fade
resistance lap after lap.
The slotted or drilled surfaces provide enhanced friction, better gas
evacuation, and improved pad bite, maintaining maximum braking stability
even at high temperatures.
Why They Fail
Under intense track conditions, brake discs can experience heat
cracks, glazing, or warping from repeated high-speed stops and extreme
thermal cycling. Poor cooling, contaminated pads, or excessive wear can lead to
vibration, noise, or reduced friction levels - compromising performance and
safety.
Why They Should Be Replaced
Replacing worn or heat-damaged discs restores peak
braking performance, consistent pedal feel, and structural integrity. New
Brembo Track Day discs ensure optimal balance between strength, weight, and
heat control, allowing drivers to brake later, harder, and with full
confidence.
For Porsche enthusiasts who drive aggressively on track or mountain roads,
upgrading to Brembo Track Day discs delivers race-quality performance with
enhanced safety, longevity, and braking precision.
