SHW Performance 34 21 2 283 387 Rear Left Perforated Vented Two-Piece Brake Disc Rotor 350x24mm

The SHW Performance 34 21 2 283 387 is a premium two-piece, internally vented and perforated brake disc rotor engineered as a direct OEM replacement. Measuring 350mm in diameter with a 24mm width, this rear axle left rotor is built to the same exacting standards SHW supplies directly to major European automakers.

SHW Performance is one of the world's leading brake disc manufacturers, serving as an original equipment supplier to top-tier automotive brands. This rotor is the identical product developed and supplied to OEMs — now available directly to consumers without the OEM price premium.

Key Features:

• Two-piece composite construction — features a cast iron friction ring paired with a lightweight aluminium disc bell for reduced unsprung weight
• Perforated face drilling — cross-drilled pattern improves initial brake bite, outgasses heat and gases from the pad surface, and helps keep rotor temperatures in check
• Internally vented design — directional internal vanes channel airflow through the rotor core for superior heat dissipation and reduced brake fade
• 350 x 24mm dimensions — rear axle left (driver's side) fitment with precise OEM-matching geometry
• OEM-certified manufacturing — every step from casting to machining is performed entirely in-house in Germany under strict OEM quality standards
• Direct OEM replacement — engineered to deliver factory-level reliability, fitment, and braking performance right out of the box

SHW manufactures both its aluminum and iron casting entirely in-house, ensuring maximum quality control at every stage of production. The result is a brake disc rotor with high thermal conductivity, precise metallurgy, and outstanding resistance to warping and fade — whether for daily driving or spirited use.
