What Makes the Z23 Series Different?

The Z23 Evolution Sport Series sits above PowerStop’s OE replacement Z17 lineup.

It was designed for drivers who want:

• Stronger braking performance
• Better heat management
• Reduced brake dust
• Improved rotor durability
• Sportier driving confidence

Without introducing the excessive noise and harshness often associated with aggressive performance brakes.

Carbon-Fiber Ceramic Brake Pads

The centerpiece of the K8817 package is the Z23 carbon-fiber ceramic brake compound.

Improved Stopping Power

Carbon-fiber reinforcement helps improve:

• Initial bite
• Pedal response
• Brake torque
• Heat resistance

Compared to standard ceramic brake pads.

Low Dust Formula

PowerStop’s testing shows approximately 30% less brake dust compared to many OE brake systems.

Benefits include:

• Cleaner wheels
• Less brake residue
• Reduced maintenance
• Better appearance

For luxury SUVs with large alloy wheels, this is a major advantage.

Quiet Operation

The Z23 pads utilize:

• Multi-layer rubberized shims
• Precision slotting
• Chamfered edges

These features help eliminate:

• Squealing
• Vibration
• Harsh brake noise

The result is premium-level braking comfort.

Drilled and Slotted Performance Rotors

One of the biggest upgrades included in the K8817 package is the rotor design.

Enhanced Cooling

The drilled holes and rounded slots help:

• Dissipate heat faster
• Reduce brake fade
• Improve consistency
• Maintain braking performance under load

This becomes especially useful when:

• Carrying passengers
• Driving in mountains
• Towing light loads
• Descending long grades

Debris and Gas Removal

Slots continuously clean the pad surface by removing:

• Brake dust
• Water
• Gases
• Debris

This helps maintain consistent pad contact.

Zinc-Plated Protection

The Silver Zinc Dichromate finish helps protect against:

• Rust
• Corrosion
• Rotor hat discoloration

The rotors maintain a cleaner appearance behind open wheels.

Designed for Everyday Performance

While the K8817 offers noticeable performance improvements, it’s still designed for daily-driven vehicles.

Perfect for:

• Family SUVs
• Luxury crossovers
• Highway commuting
• Weekend travel
• Light towing duties
• Urban stop-and-go traffic

It strikes an excellent balance between comfort and performance.
