GiroDisc A1-162 Slotted 2-Piece Front Rotors for 2015-2020 Ford Shelby GT350/GT3

Vehicle Fitment

• Ford Mustang Shelby GT350 / GT350R (2015-2020, front axle)

Features

• 2-piece floating rotor design - aluminum hat + cast-iron rotor ring for reduced unsprung & rotational mass
• Slotted, vented rotor face to improve pad bite, shed gases/debris, and resist fade under heavy braking
• Curved-vane internal ventilation - acts like a centrifugal pump to draw air through the rotor for improved cooling
• Floating-mount system with high-strength alloy steel drive pins and anti-noise spring washers - allows thermal expansion and self-centering without rattle
• Direct-bolt replacement - uses OEM calipers and pads, no modifications required
• Re-useable hat design - when rotor rings wear out these can be replaced without replacing the entire rotor assembly
• Designed for track-day and performance street use - ideal for repeated heavy braking, spirited driving and track conditions
• Made in USA - aluminum hats and cast-iron rings manufactured and assembled domestically for high quality and consistency

Product Description

The GiroDisc A1-162 rotor set is a performance-grade upgrade engineered specifically for the front brakes of 2015-2020 Ford Mustang Shelby GT350 / GT350R. By replacing the stock one-piece rotors with lightweight, floating 2-piece rotors, A1-162 reduces unsprung and rotating mass - this enhances suspension response, braking feel, and steering precision, especially during aggressive or track driving. The slotted rotor surface aids pad bite and helps purge brake-dust, gasses, and water, improving consistency under repeated hard stops.

Thanks to the curved-vane ventilation design, these rotors clear heat efficiently, maintaining cooler brake temperatures under heavy braking (e.g. track days, canyon runs, spirited driving). The floating-hat setup uses a sturdy aluminum hat and steel pins with anti-rattle washers - this allows the rotor to expand and self-center when hot, while still remaining quiet and reliable on the street. Installation is straightforward: the A1-162 bolts directly to the stock hub and works with OEM calipers and pads - no special modification required. For GT350/GT350R owners looking for improved brake response, reduced unsprung weight, and better cooling under load - A1-162 is a top-quality choice.
