StopTech 228.37035 Sport Slotted Disc Brake Rotor

The StopTech 228.37035 is a Sport slotted disc brake rotor engineered as a direct-fit replacement for factory brake systems. Designed to deliver meaningful performance gains over OEM rotors, this rotor features precision slotting to improve wet and dry braking performance while maintaining the structural integrity of the friction surface.

Key Features:

• Slotted rotor design vents hot gases and clears brake dust from the pad-to-rotor interface, improving initial bite and reducing fade
• Superior metallurgy with engineered vane geometry promotes cooler operating temperatures compared to standard replacement rotors
• Black E-coat finish (electrostatically applied) protects the hat and cooling vanes from corrosion and is designed to withstand 400 hours of saltwater exposure without rusting
• High-carbon iron construction on select applications for improved crack resistance, quieter operation, and reduced NVH
• 1-piece direct replacement — bolts directly to factory hubs and works with OEM calipers; no modifications required
• Slotting removes only a minimal portion of rotor surface area to preserve maximum pad-to-rotor contact and coefficient of friction

StopTech Sport rotors are sold individually and represent one of the most cost-effective performance brake upgrades available for street-driven vehicles. Each rotor is produced from a high-quality casting and finished to strict dimensional tolerances for proper fitment and smooth, vibration-free operation right out of the box.
