SHW Performance BFL48251 Front Left Cross-Drilled Rotor BMW M2 Competition

Vehicle Fitment

• 2019-2021 BMW M2 Competition (F87, S55 3.0L Twin-Turbo I6, RWD, Coupe)

Fitment Notes

• This is the Front Left (driver side) rotor only - sold individually. Right side rotor available separately as BFR48252 (OEM: 34118072018).
• Two rotors required for a complete front axle replacement.
• Direct OEM replacement for part number 34118072017.
• Does NOT fit the 2016-2018 BMW M2 (base/N55) or models equipped with M Carbon Ceramic Brakes (option S2NKA). Confirm standard iron rotor fitment before ordering.
• Does NOT fit the BMW M2 CS unless verifying standard brake fitment.
• Professional installation and proper break-in bedding procedure required after installation.

Features

• Cross-drilled disc surface enhances heat dissipation, reduces brake fade during sustained high-performance driving, and improves initial pad bite - well suited to the S55's 405 hp output and the M2 Competition's track-oriented character.
• SHW's patented Pin-Drive two-piece construction - cast iron friction ring connected to a lightweight aluminium disc bell via stainless steel pins - significantly reduces unsprung and rotational mass versus conventional one-piece cast iron designs.
• Fully floating Pin-Drive design minimizes brake judder, accommodates thermal expansion more effectively, and opens central cooling channels for up to 50% greater airflow and heat dissipation versus traditional designs.
• Manufactured by SHW Performance - a premier OEM brake disc manufacturer, jointly developing its Pin-Drive rotor technology with BMW Motorsport since 1993, and a direct supplier of brake rotors to BMW M-series vehicles from the factory.
• Engineered to meet OEM specifications for dimensional accuracy, metallurgy, and braking performance.
• Made in Germany.

Product Description

The SHW Performance BFL48251 is a front left cross-drilled lightweight brake rotor engineered as a direct OEM-equivalent replacement for the 2019-2021 BMW M2 Competition (F87), replacing OEM part number 34118072017. SHW Performance's relationship with BMW M dates to 1993 when it jointly developed its Pin-Drive rotor technology with BMW Motorsport - the same fundamental design that went on to become standard equipment on BMW M-series production vehicles. The BFL48251 delivers that same factory-specification component directly to the consumer.

At 400 x 36 mm, this two-piece Pin-Drive rotor matches the M2 Competition's larger front brake package (specific to the S55-powered Competition model, not shared with the base N55 M2) and is sized for the sustained, repeated braking demands of a 405 hp rear-wheel drive track-capable coupe. The cross-drilled disc face promotes airflow across the friction surface and sharp initial bite, while the lightweight aluminium bell and Pin-Drive floating construction cut rotational and unsprung mass versus conventional one-piece iron rotors. The offset pin connection maximizes central cooling channel airflow for up to 50% better heat dissipation under hard use. This is the front left (driver side) rotor only - the right side is sold separately as BFR48252. Two rotors are required for a complete front axle service. Does not fit the standard 2016-2018 M2 (N55) or ceramic brake-equipped models. A proper break-in bedding procedure is required after installation.
