StopTech 121.51018 Premium Cryogenic Slotted Brake Rotor

The StopTech 121.51018 Premium Cryogenic Slotted Brake Rotor delivers enhanced braking performance through advanced metallurgy and precision engineering. This high-quality replacement rotor features StopTech's proprietary cryogenic treatment process that stabilizes the metal structure, reducing thermal stress and extending rotor life.

Key Features:

• Cryogenic stress relief treatment for improved durability and thermal stability
• Precision machined slots to dissipate heat and evacuate brake dust and gases
• Double disc ground finish ensures consistent pad contact and reduced break-in time
• Mill balanced to strict tolerances to eliminate vibration and noise
• E-coating provides superior corrosion resistance on non-friction surfaces
• Direct OE replacement fitment for hassle-free installation

StopTech's cryogenic treatment process subjects the rotors to extreme cold temperatures, which relieves internal stresses in the metal and creates a more uniform grain structure. This results in a rotor that is more resistant to cracking and warping under extreme heat cycling. The precision-machined slots help maintain consistent pad bite by continuously refreshing the pad surface and preventing glazing, while also improving wet weather performance by channeling water away from the contact surface.
