Company Profile
Products
OE-matched, meeting IATF 16949, ECE R90, and Tesla’s heavy-duty standards. Fits original calipers/holes for direct bolt-on installation, no modifications needed.
Precision-ground friction surface reduces resistance fluctuations; ventilated vanes enhance airflow, ensuring smooth braking and less pedal judder under load.
Anti-corrosion coating (zinc-nickel/Geomet) passes salt spray tests, resisting peeling despite thermal cycles from heavy braking.
NVH-optimized: non-directional machining cuts vibration; damping components reduce noise. Wear-resistant treatment minimizes dust.
Optimized ventilation increases heat dissipation; high-carbon cast iron stays stable at high temps. Slotted variants (if applicable) expel hot debris, reducing fade.
Seamless with Tesla’s system, avoiding force mismatch and keeping factory braking feel.
Stable braking in heavy use (hauling/towing) via precision design and ventilation.
Long life: corrosion resistance and wear-resistant material reduce replacement needs.
Quiet, clean operation: less noise and dust keep wheels tidy, lowering maintenance.
Heat resistance prevents fade or deformation, ensuring safety in continuous heavy use.
This product fits the following Tesla models (specific fitment depends on model year, brake system configuration, and drivetrain):
| Model | Year Range | Position | Notes |
|---|---|---|---|
| Model S | 2012–2020 (pre/post) | Front/Rear | Performance trim or standard |
| Model X | 2015–2020 (pre/post) | Front/Rear | Performance trim or standard |
| Model 3 | 2017–2023 (pre/post) | Front | Performance trim |
| Model Y | 2020–2023 (pre/post) | Front | Performance trim |
Note: Different model years and drivetrain configurations (single/dual/triple motor) may have different disc sizes. Standard and Performance trims have different disc specifications. Before purchase – confirm based on the part number on the original disc or actual measurements. This product fits Tesla models originally equipped with cast-iron discs – not applicable to carbon-ceramic disc configurations.
Summary
Steel Hat Thermal Expansion Matching: Steel and cast iron have closer CTEs – lower thermal stress at the connection interface at high temperatures – higher connection reliability than aluminium-hat designs.
Regenerative Braking Condition Adaptability: Accommodates three conditions – low friction brake usage in typical driving – high temperature resistance under emergency braking – independent braking load handling when regenerative braking is limited.
Thermal Management Redundancy Design: Provides adequate friction braking force and heat capacity when regenerative braking is unavailable (full battery, extreme cold) – ensuring braking safety.
Installation Torque & Handling Guidance: Torque per Tesla service manual; steel-hat discs are heavier – take care for personal and component safety during installation.
Bedding-In Adapts to EV Characteristics: With regenerative braking reducing friction brake frequency – bedding-in time may be longer than ICE vehicles; moderate increase in light-to-medium brake applications recommended.
