This rotor ring is a direct replacement for Paragon two piece performance rotor PN P2R.190.365.260.24000.05.01.01.R and does not fit your stock vehicle without the two piece rotor hat, unless specifically stated.

Replacement Rotors for Chevrolet Corvette Z06 (C7)/Grand Sport / Camaro SS 1LE (6th Gen) - Rear Pair

These rotors fit the following models

• 2014-2019 C7 Corvette Z06 (J56 brakes, w/o Z07 package)

• 2017-2019 C7 Corvette Grand Sport (J56 brakes, w/o Z07 package)
  

Paragon Performance Rotor Ring offers superior braking and cooling efficiency optimized for track and race applications. It features directional ventilation vanes to create suction, turbulence, and guides cool air through the rotor for improved heat dissipation and increased resistance to cracking under harsh track condition.

Made of CM-250 special formulated high carbon alloy cast iron, it allows for an optimal bite, thermal characteristics, high-temperature strength and durability. Rotor rings are heat treated to release stress in the rotor to avoid deformation and vibration then turned by state-of-the-art CBN surface machining to ensure better break-in with new brake pads.

Vibration is reduced as the rotor lateral run-out is kept within 0.03mm and well-balanced: variations are kept within 2 grams. All rotor rings went through rigorous quality control procedures and inspections to ensure the rotor rings are fit for their purposes.

Heavy use can cause stock Chevy rotors to crack early due to vehicle weight and poor cooling. These upgraded rear rotors fit OE hats and help prevent cracking while improving pedal feel and brake control.

Directional ventilation vanes for optimal cooling performance and increased resistance to cracking. Run up to 30% cooler than O.E. rotors and increase cooling efficiency by up to 30%

• Fully-floating 2-piece design
• Minimizing brake fade & judder during extended sessions

Part Number: PRK.190.365.260.24000.05.01.R

Best For: Corvette, Camaro, and Cadillac V Applications

These rotors are well suited for GM performance platforms that see high-speed street driving or occasional track use. They help support the kind of repeatable braking feel these cars need when speed, tire grip, and vehicle capability all move beyond ordinary street-car use.

FAQ

Do these fit the factory rotor hats?
These rotor rings fit Paragon hats, or the original equipment hats when the vehicle came with a factory 2-piece rotor design. If your application uses a 1-piece factory rotor, these are not intended to bolt to an OE hat because there is no separate hat to reuse.

Are these complete rotors or replacement rings?
These are replacement rotor rings only. They are designed to service the braking surface while reusing the existing hat when the hat is compatible.

Do slotted rotors improve braking?
Slots primarily improve pad cleaning and help maintain consistent braking feel under heat. They do not create a dramatic change in stopping distance by themselves, but they can help the system stay more consistent during repeated hard stops.

When should rotor rings be replaced?
A practical wear indicator is slot depth. When the slots become shallow and much less visible, the rotor is typically nearing the end of its effective service life. Rotor thickness, heat checking, cracking, and brake vibration should also be inspected during service.

Should I replace pads at the same time?
Yes, in most cases. Fresh pads help the new rotor surface bed in correctly and reduce the chance of uneven deposits, noise, or inconsistent pedal feel.

Brake Rotor Technology

Why high-carbon rotors matter
High-carbon cast iron offers better thermal stability than generic low-cost rotor materials. That helps the rotor maintain more consistent behavior as temperature rises, which is important on heavier vehicles and on cars driven aggressively.

Directional vane cooling
Directional internal vanes are designed to move air through the rotor more effectively, improving heat evacuation and helping the rotor recover more quickly between braking events.

Slotted rotor surface
Slots help keep the pad face clean by clearing away gases, dust, and debris. The result is more consistent pad contact and more repeatable braking feel, especially when the system is worked hard.

When to Replace Rotor Rings

Rotor rings should be replaced when the friction surface shows meaningful wear, heat fatigue, or thickness loss. One of the easiest visual indicators is the depth of the rotor slots. As the rotor wears, the slots become shallower. When they are much less visible, the rotor is generally nearing the end of its useful service life.

Other common signs include visible heat checking or cracking, brake pulsation, heavy scoring, and rotor thickness approaching the service limit.

Why Replace Rotor Rings Instead of the Whole Rotor?

On vehicles that use 2-piece rotors, the friction ring can be replaced independently from the hat. That allows the wear component to be serviced without replacing the full assembly, which can reduce replacement cost while preserving the benefits of the 2-piece design.

Common Mistakes When Replacing Rotors

• Reusing worn pads on a fresh rotor surface
• Skipping the pad and rotor bedding process
• Not cleaning or inspecting the hat, hardware, and mounting faces
• Ignoring brake fluid condition during brake service
• Ordering the wrong configuration for the vehicle or hat type

Taking care of these details helps the new rotor deliver the braking feel, wear life, and consistency it was designed to provide.

Recommended Companion Parts

Rotor service is also a good time to inspect or replace the brake pads, rotor hardware where applicable, and brake fluid. On performance applications, fresh pads and fluid often have as much impact on brake feel as the rotor itself.
