StopTech 121.63035 Sport Plain Brake Rotor

The StopTech 121.63035 is a Sport Plain brake rotor engineered as a direct OEM replacement with enhanced performance characteristics. Designed for drivers who want a meaningful upgrade over standard factory rotors without the added surface modification of slotted or drilled designs, this plain-face rotor delivers reliable, consistent stopping power for everyday street driving and light performance use.

StopTech Sport Plain rotors are manufactured from premium high-carbon iron castings and finished with a protective black e-coat (electrocoating) that provides corrosion resistance in the hat and vane areas. The advanced metallurgy—including elevated carbon content with added molybdenum and chromium in select applications—reduces noise, vibration, and harshness (NVH) while improving crack resistance and overall rotor longevity.

Key Features:

• Direct OEM replacement fit — compatible with factory calipers and hardware
• High-carbon iron construction for quieter operation and improved thermal stability
• Black e-coat finish rated to withstand 400+ hours of saltwater exposure without rusting
• Engineered vane design promotes cooler operating temperatures and reduces brake fade
• Manufactured to meet or exceed OEM specifications for thickness, balance, and runout
• No break-in bedding procedure beyond standard pad seating required
• Sold individually — single rotor
