StopTech Slotted Sport Brake Rotor for BMW 318i, 325i, 325is, 325e – Part Number 126.34019SL

Description

Upgrade your BMW with the StopTech Slotted Sport Brake Rotor, designed as a direct replacement for factory brake systems on select BMW models including the 318i, 325i, 325is, and 325e. These high-performance, single-piece rotors feature advanced slotting that enhances heat dissipation, brake dust removal, and pad engagement, resulting in improved braking response and shorter stopping distances in both wet and dry conditions. The sleek black e-coating offers corrosion resistance, while the high carbon metallurgy ensures durability, quieter operation, and superior crack resistance even under demanding driving conditions.

The rotors are double ground for a consistent friction surface, which contributes to smooth braking performance and reduced pad squeal, especially effective with higher friction European-style brake pads. The inclusion of molybdenum and chromium in the alloy further enhances resistance to thermal cracking, extending the rotor’s lifespan. Selected models feature directional curve vane designs to optimize airflow and heat management, while cryogenic treatment reduces residual stress for reliable operation. Slots in the rotor help evacuate gasses, dust, and heat effectively, maintaining consistent braking feel over time.

These rotors are engineered as direct OE replacements, ensuring perfect fitment and easy installation. Whether you’re looking to improve your vehicle’s stopping power or enhance its appearance, the StopTech Slotted Sport Brake Rotor offers a significant upgrade over stock parts, combining advanced metallurgy, corrosion protection, and high-performance slotting technology for a safer, more responsive driving experience.
