BMW ActiveHybrid 3 Brake Rotor (1) - Rear Left - Stoptech - Slotted Sport - Black - `13-`15. This StopTech one-piece slotted sport rotor is a direct OE replacement designed for the rear left of 2013–2015 ActiveHybrid 3 applications, offering improved braking response and durable corrosion resistance.

Built for drivers who want better initial bite and consistent stopping performance without changing calipers, this rotor features StopTech’s slotted face to evacuate gases, dust and heat while reducing pad glazing. The black e-coating provides long-term corrosion protection for a cleaner finish behind your wheels. StopTech’s advanced metallurgy (used in most applications) reduces pad squeal and improves resistance to thermal cracking; select designs also use directional vane geometry and cryogenic stress relief to maintain a consistent friction surface under repeated use.

Features

• One-piece slotted sport rotor — direct OE replacement for stock calipers
• Black e-coating for corrosion protection and cleaner appearance
• Slots to improve pad bite, dust/gas evacuation and wet-weather response
• Advanced metallurgy with added Moly/Chromium and cryogenic treatment for crack resistance
• Double-disk ground friction surface for consistent pedal feel
