Key Features

• Slotted and cross-drilled surface helps move heat, gas, dust, and moisture away from the friction area.
• Silver zinc dichromate coating resists rust and surface corrosion.
• Vented rotor design supports heat dissipation during repeated braking.
• Direct OE fit with no special modifications needed.
• 5-lug, 114.3 mm bolt circle specification.

Detailed Description

PowerStop JBR552XPR is a front disc brake rotor set for Nissan 300ZX models with the specified fitment. The slotted X-drilled surface is intended to maintain a cleaner contact patch by sweeping away gases, dust, and moisture, while the vented rotor construction helps manage heat under demanding braking conditions. The zinc dichromate finish adds rust resistance for long-term service. This part number, JBR552XPR, is a direct OE-style replacement for 1989-1996 Nissan 300ZX front brake applications, including 1990 models built from 7/90.

Power Stop’s drilled and slotted rotor line focuses on bolt-on replacement parts that preserve factory fit while adding surface features commonly used for cooling and rotor maintenance. For buyers searching for Nissan 300ZX front drilled and slotted brake rotors, JBR552XPR provides a fitment-specific option with the dimensions and mounting pattern listed in the product data. This part cross-references Monroe Shocks & Struts (e.g., 120.42050, 31126) for the same application.

What It Is Used For

• Replacing worn front brake rotors on a Nissan 300ZX.
• Addressing brake pulsation caused by rotor wear or surface irregularity.
• Improving heat management during repeated stops.
• Reducing buildup of dust, gas, and moisture on the rotor face.
• Restoring proper braking contact with a direct-fit rotor design.

Installation Notes and Tips

Fits 1989 Nissan 300ZX, front. Fits 1990 Nissan 300ZX, front, from 7/90. Fits 1991-1996 Nissan 300ZX, front. Verify rotor diameter, thickness, and bolt pattern before installation.
