Kia Composite Grooved Brake Discs

Brake Discs Features

1. OE-matched for Kia lineups: Fits K5 GT, Sportage, Sorento, and Niro EV; ECE R90/IATF 16949 certified, supporting direct bolt-on installation (no modifications).

2. Composite structure advantage: High-carbon cast iron friction ring (wear-resistant) + lightweight alloy hat (reduces unsprung weight by ~15%), balancing durability and handling.

3. Optimized grooved design: 6–8 radial grooves clear brake dust, rainwater, and gas buildup; maintains stable friction even in wet or heavy-braking conditions.

4. Anti-corrosion protection: Zinc-nickel or Geomet coating on the hat and friction ring edges, passing salt spray tests to resist road salt and moisture.

5. NVH optimization: Non-directional friction surface + damping shims minimize braking noise and vibration, preserving cabin comfort for family use.

Brake Discs Benefits

1. Seamless Kia system compatibility: Works with ESC and hybrid regenerative braking, keeping the factory braking feel and avoiding "force mismatch" during emergency stops.

2. All-scenario braking stability: Grooves prevent fade in K5 GT’s sporty driving; composite durability handles Sorento’s heavy loads (full cargo + towing).

3. Extended service life: Wear-resistant cast iron + anti-corrosion coating reduce replacement frequency by ~25% vs. standard discs, lowering maintenance costs.

4. Quiet & clean experience: Low noise suits family rides; minimal dust keeps Kia’s alloy wheels tidy (critical for Sportage/Niro’s sleek design).

5. Improved daily handling: Lightweight composite structure enhances steering responsiveness, making city driving (e.g., Sportage) more agile.

1. Kia Vehicle Coverage: Sportage, Sorento, Telluride, Forte & K5

Our catalog covers the full Kia lineup including Sportage, Sorento, Telluride, Forte, K5, Soul, Seltos, Niro, and Stinger — ensuring the correct composite grooved brake disc for every popular Kia vehicle.

2. Composite Two-Piece Construction: Weight Reduction & Heat Dissipation

These Kia brake discs feature a composite two-piece construction with a lightweight hat bonded to a high-carbon cast iron friction ring — reducing overall disc weight by up to 20% while improving heat dissipation and reducing unsprung mass.

3. Grooved Friction Surface: Enhanced Pad Bite & Gas Evacuation

These Kia brake discs feature precision-machined grooves across the friction surface that enhance pad bite, evacuate brake gas and water from the pad-disc interface, and improve initial bite in wet conditions — ideal for performance-oriented driving.

4. High-Carbon Friction Ring: Consistent Braking for Daily Driving

These Kia composite brake discs feature a high-carbon cast iron friction ring that provides superior thermal conductivity, consistent friction characteristics, and enhanced wear resistance — delivering smooth, predictable braking performance in all driving conditions.
