StopTech 121.99105 Sport Slotted Brake Rotor

The StopTech 121.99105 is a Sport Slotted brake rotor engineered for drivers who demand improved stopping power and rotor longevity over standard OEM replacements. StopTech's slotted rotor design continuously cleans and deglazes brake pads during every stop, ensuring consistent, fade-resistant braking performance under both everyday driving and spirited use.

Key Features:

• Slotted rotor face — slots sweep away gas, dust, and debris from the pad/rotor interface for a cleaner, more consistent bite
• Direct OEM replacement fit — designed as a bolt-on upgrade with no modifications required
• High-carbon iron construction — reduces noise, vibration, and harshness (NVH) while improving thermal capacity
• Geomet® protective coating — corrosion-resistant finish minimizes rust bloom on the rotor hat and non-swept surfaces
• Precision machined — tight tolerances ensure minimal runout and smooth, vibration-free braking
• StopTech Sport series — a proven upgrade step above standard blank replacement rotors

The StopTech 121.99105 rotor is manufactured to strict quality standards and is an ideal choice for drivers looking to upgrade braking performance without moving to a full big brake kit. Compatible with StopTech, Hawk, EBC, and other performance brake pads for a complete braking system upgrade.
