Fitment Notes

• Position: Front axle only for all applications listed above.
• Not compatible with carbon ceramic rotors. For use with iron/metal rotors only.
• This pad fits the OEM front caliper on covered Porsche 911 and Cayman models equipped with standard iron front rotors only. All entries note "Exc.Ceramic Composite Brakes" - vehicles equipped with the optional Porsche Ceramic Composite Brake (PCCB) system use carbon ceramic rotors and are incompatible with this or any Ferro-Carbon or ceramic compound brake pad. Confirm your vehicle's brake system type before ordering.
• The 2015 Porsche 911 entry includes a specific "Iron Brakes" notation in Hawk's fitment database, explicitly identifying standard iron-rotor configurations covered by this pad.
• The 911 GT3 and GT3 RS models are equipped with Porsche's high-performance front caliper as standard equipment on iron brake systems. The 991.1 GT3 uses a 3.8L naturally aspirated flat-six; the 991.1 GT3 RS and 991.2 GT3/GT3 RS use a 4.0L naturally aspirated flat-six.
• The Cayman GT4 (981, 2016) uses the 3.8L naturally aspirated flat-six shared with the 991.1 GT3. The 718 Cayman GT4 (982, 2020) uses a new 3.8L naturally aspirated flat-six (9A2.50). Both are rear-wheel drive.
• The standard 991 Cayman (2016, bare entry) covers base and S variants with standard iron front brakes.
• No electronic wear sensor or hardware is included with this pad set.

Features

• Performance Ceramic compound - Hawk's premium ultra-low dust, ultra-quiet ceramic composite formulation engineered to meet and exceed the low-noise and low-dust performance standards of OEM ceramic pads while delivering improved front stopping power over stock replacement compounds - an ideal upgrade for Porsche 911 and Cayman owners who use their cars primarily on public roads and want to dramatically reduce the heavy front wheel contamination characteristic of OEM Porsche front brake pads.
• Ultra-low dust output - The single most compelling reason to choose Performance Ceramic on these Porsche platforms: OEM Porsche front brake pads are notorious for producing extremely heavy dark brake dust that rapidly coats the front wheels of the 911 and Cayman. The Performance Ceramic compound eliminates the majority of this contamination, preserving the appearance of the front alloys between washes - a significant practical benefit on vehicles where wheel aesthetics are closely maintained.
• Extremely quiet front brake operation - Engineered specifically to reduce brake NVH (Noise, Vibration, and Harshness), the Performance Ceramic delivers near-silent front brake engagement in all driving conditions, eliminating the cold-morning squeal that OEM Porsche front pads often exhibit and preserving the refined driving experience expected of these premium sports cars on public roads.
• Linear friction profile for enhanced ABS performance - The ceramic compound's stable, progressive friction coefficient allows the 911 and Cayman's ABS system to operate in its optimal engagement zone, enabling more effective modulation of front brake force during threshold braking and improving total stopping consistency on these high-performance RWD and AWD platforms.
• Improved front stopping power over OEM replacements - Delivers better front stopping power than standard OEM replacement compounds, improving overall braking balance and contributing to shorter total stopping distances while maintaining the quiet, clean characteristics that define the ceramic compound.
• Reduced front pad and rotor wear - The ceramic formulation produces lower abrasive wear on both the pads and front iron disc surfaces compared to Ferro-Carbon compounds, extending service intervals and reducing the long-term brake maintenance costs on these premium platforms.
• Stable friction output across temperature range - Maintains a consistent friction coefficient from cold ambient through elevated street operating temperatures, delivering predictable, repeatable front brake behavior on the 911 and Cayman from the first cold stop through sustained spirited street driving.
• 100% asbestos, lead, chromium, cadmium, and antimony free - Manufactured in an ISO-certified facility to strict quality and environmental standards.

Product Description

The Hawk HB848Z.646 Performance Ceramic front brake pads fit the OEM front caliper of the Porsche 911 (991 and 991.2 generations, 2014-2019) and Porsche Cayman (981 and 982 generations, 2016-2020) with standard iron front brake systems. Covered 911 variants include the base Carrera/S/4/4S lineup as well as the GT3, GT3 RS, spanning the 3.4L, 3.8L, and 4.0L naturally aspirated flat-six engines. Cayman fitment covers the 981 Cayman GT4 (3.8L) and 982 Cayman GT4 (3.8L) along with the standard 981 Cayman. All applications must be equipped with standard iron front rotors - vehicles with the optional Porsche Ceramic Composite Brake (PCCB) system are incompatible with this compound.

Performance Ceramic is the most practical daily-driver front compound upgrade for these Porsche models. The OEM front brake pads on the 911 and Cayman are well-known for generating extremely heavy, dark brake dust that rapidly coats the front wheels - a persistent frustration for owners who maintain the appearance of their cars. The Performance Ceramic compound addresses
