Brake Discs Features:                                                   

•Equivalent to OE design 

•Smooth and quick stop 

•Anti-rust 

•Low noise, low dust 

•Optimal thermal performance 

• Slotted Friction Geometry for Enhanced Pad Bite:

The precision-machined slots across the friction surface serve a critical performance function: they evacuate trapped gas and brake dust that can build up between the pad and disc under heavy braking, maintaining direct pad-to-disc contact and delivering sharper, more immediate pedal response. This slotted design also helps prevent pad glazing and preserves consistent friction performance during aggressive driving and repeated high-speed stops.

• 348mm Large-Diameter Braking Torque (348mm × 67mm):

With a substantial 348mm diameter and 67mm total height, this high-performance slotted brake disc provides increased leverage and greater braking torque compared to standard-size rotors. The larger friction surface area distributes heat across a wider zone, reducing localized hot spots and extending the effective service life of both the disc and matching brake pads.

• Ventilated Internal Vane Cooling Structure:

The ventilated disc design features an internal vane structure that channels airflow through the disc as it rotates, actively drawing heat away from the friction surfaces and accelerating thermal dissipation. This forced-air cooling effect reduces peak operating temperatures during sustained heavy braking, mitigating brake fade and maintaining consistent pedal feel even during prolonged downhill descents or track-style driving.

• High-Carbon Gray Iron Thermal Cycling Resistance:

Cast from G3000 and GG15HC high-carbon gray iron formulated to DIN and SAE standards, the disc is engineered to withstand the extreme thermal cycling inherent to performance driving. The elevated carbon content enhances both thermal conductivity and structural flexibility, reducing the risk of cracking, warping, and permanent distortion that can occur when lesser discs are exposed to rapid temperature swings.

• Multi-Option Anti-Corrosion Finishes (Oiled / Painted / Coated / Zinc-Dust):

Available with a selection of protective surface treatments including oiled, painted, coated, and zinc-dust finishes, each formulated to shield the disc from environmental corrosion, road salt, and moisture. These treatments not only extend service life but also preserve a clean, aesthetically pleasing appearance — particularly important for performance vehicles where the brake disc is visible through the wheel spokes.

• Globally Certified Performance Manufacturing:

Produced in an IATF16949-certified facility with full ECE R90 and AMECA compliance, and supported by ISO14001 environmental and ISO14001 occupational health management systems. Each slotted disc undergoes rigorous dimensional inspection, slot geometry verification, and dynamic balance testing before packaging in boxes, cartons, pallets, or bulk configurations for worldwide distribution.

Brake Pads Features:

•High performance 

•Long-life service 

•Anti-fade 

•Low noise, low dust 

•Environmental friendly

• Performance-Matched Friction Compound:

Formulated to complement the slotted high-performance disc design, the pads deliver a high and stable coefficient of friction that provides strong, predictable stopping power across a broad temperature range. The compound is engineered to work in harmony with the slotted surface, maximizing pad bite and minimizing gas-layer interference.

• Extended Service Life Under Performance Use:

The wear-resistant friction formulation and heavy-duty steel backing plate are built to withstand the increased mechanical demands of performance driving, delivering extended service life even under aggressive use. The pads resist uneven wear and maintain consistent thickness throughout their service interval.

• Thermal Fade Resistance for Demanding Conditions:

Engineered to resist brake fade at elevated temperatures, the pad compound retains its friction characteristics during repeated hard stops and sustained high-speed deceleration. This prevents the spongy pedal feel and increased stopping distances associated with thermal fade, giving drivers consistent, confidence-inspiring performance.

• Low-Noise, Low-Dust Operation:

Precision-ground friction surfaces and chamfered edges reduce brake squeal and vibration, while the low-dust formulation minimizes unsightly residue on alloy wheels. The slotted disc design further aids dust evacuation, keeping wheels cleaner and the cabin quieter even during performance-oriented driving.

• Environmentally Conscious Production:

Manufactured under ISO14001-certified environmental management systems, the pads are produced with resource-efficient processes and formulations designed to minimize environmental impact. The production prioritizes responsible material sourcing and waste reduction without compromising braking performance or durability.
