GiroDisc A1-288 2-Piece Slotted Front Rotors for 2022-2025 VW Golf R (Mk8)

Vehicle Fitment

• 2022-2025 Volkswagen Golf R (Mk8, 4Motion, front axle)
• 2022-2025 Audi S3 (8Y, Quattro, front axle)

Features

• 2-piece floating rotor design - 6061-T6 aluminum hat + proprietary high-carbon cast-iron rotor ring for reduced unsprung and rotating mass
• Slotted & vented rotor surface - improves pad bite, dust/gas/debris purge and wet-weather braking performance
• Curved-vane internal ventilation (72 vanes) - draws cooling air through the hub for superior thermal management under repeated braking
• Fully floating mount system - cadmium-plated alloy steel drive pins, Belleville washers and spring clips allow thermal expansion and self-centering without noise
• Direct OEM bolt-on replacement - works with stock calipers and hubs, no adapters or modifications required
• Re-useable hat design - when rotor rings wear down, you can replace rings only (part number D1-288) instead of entire rotor assembly
• Significant reduction in unsprung / rotational mass - improves suspension response, steering feel and braking modulation
• Manufactured in USA from domestically-sourced materials - high precision machining and quality control standards

Product Description

The GiroDisc A1-288 2-Piece Slotted Front Rotor set is a premium performance brake upgrade designed specifically for 2022-2025 Volkswagen Golf R (Mk8) and 2022-2025 Audi S3 (8Y). By replacing the heavy factory rotors with a floating-hat design - combining a lightweight aluminum center and a high-carbon cast-iron outer ring - A1-288 reduces unsprung and rotational mass. This reduction helps sharpen suspension response, improves steering feel, and enhances braking modulation - particularly beneficial for spirited street driving or occasional track use.

The slotted and vented disc surface, along with GiroDisc's 72-vane internal ventilation, ensures efficient heat dissipation and pad-gas / debris purge even under repeated heavy braking, reducing fade and maintaining consistent braking performance. Because the rotors bolt directly to OEM hubs and accept factory calipers and pads, installation is straightforward - no adapters, machining, or calibration changes required. For long-term value, the discs are rebuildable: worn or warped rings can be replaced (with part D1-288) while reusing the aluminum hats. If you're looking to upgrade the front braking performance, reduce unsprung weight, and improve cooling on your Mk8 Golf R or 8Y S3 - A1-288 is a well-rounded, high-quality, and practical choice.
