SHW PFL39811 Left Front Drilled-Dimpled Rotor 315x28 Porsche Boxster Cayman 2.7

Vehicle Fitment

• 2013-2016 Porsche Boxster (981) - 2.7L flat-six - without ceramic brakes (PCCB)
• 2014-2016 Porsche Cayman (981C) - 2.7L flat-six - without ceramic brakes (PCCB)

Fitment Notes

• 2.7L base model specification - the PFL39811 fits the 315mm x 28mm front rotor application of the 2.7L 981 Boxster and Cayman; the higher-spec Boxster S, GTS, and Spyder, and the Cayman S and GTS, use larger front rotor specifications and different SHW part numbers; verify your vehicle's existing front rotor diameter before ordering
• Without ceramic brakes (PCCB) only - the optional Porsche Ceramic Composite Brake system uses ceramic-matrix composite rotors with a different caliper design; the PFL39811 iron rotor is not compatible with PCCB calipers and must not be installed on PCCB-equipped vehicles; verify your brake specification by checking caliper color (PCCB calipers are yellow; standard steel calipers are red or silver)
• Left front (driver side) only - one rotor per order; the matching right front rotor is SHW PFR39812 (OE# 98135140201); a complete front axle replacement requires one of each
• Sold individually - one rotor per order
• OE replacement - replaces Porsche OE part number 98135140101 (also 981-351-401-01); SHW is the OEM supplier of this rotor to Porsche for the 981 base model front brake system

Features

• True OEM-source rotor - SHW (Schwabische Huttenwerke) is the direct OEM supplier of brake rotors to Porsche for the 981 Boxster and Cayman platform; the PFL39811 is the same part produced at SHW's German facility to the same specification as the rotor installed on these vehicles at the factory; the SHW Performance consumer product line provides direct access to this OEM-specification part without the dealer margin
• Drilled-dimpled friction surface - the PFL39811 uses a combination surface treatment that Porsche specifies for the 981 base front rotor: through-drilled holes and blind dimples working together on the friction face; the through-holes provide complete outgassing channels for brake pad vaporization byproducts during heavy braking, while the blind dimples (which do not penetrate fully through the rotor) provide additional surface disruption for heat management and initial pad bite without the structural stress concentration of a fully drilled hole at those locations; the combination pattern is the factory specification for this application - not an aftermarket modification applied to a smooth rotor, but the designed surface as produced by SHW for Porsche's 981 base brake system
• 315mm x 28mm ventilated monobloc - the 315mm diameter is the front rotor specification for the 981 Boxster/Cayman 2.7L base model; the 28mm thickness with internal ventilation vanes provides continuous cooling airflow through the rotor body under braking; the monobloc one-piece cast iron construction delivers the rigidity and thermal mass appropriate for the 2.7L mid-engine sports car's braking demands in street use
• SHW manufacturing quality - SHW's integrated German facility controls every production step from iron foundry through machining and surface treatment to dimensional inspection; the drilled-dimpled surface pattern on the PFL39811 is produced during or immediately after the machining process to maintain consistent hole positioning and edge geometry across every rotor
• Directional left-front specific design - the internal vane geometry is optimized for the rotational direction of the left front wheel position; install on the left front only; the right front uses PFR39812

Product Description

The SHW PFL39811 is the left front drilled-dimpled monobloc brake rotor for the 2013-2016 Porsche Boxster (981) and 2014-2016 Porsche Cayman (981C) with the 2.7L flat-six engine and standard iron brakes - measuring 315mm in diameter and 28mm in thickness. SHW (Schwabische Huttenwerke) is the direct OEM supplier of this rotor to Porsche for the 981 base model front brake system, and the SHW Performance product line provides this factory-specification part directly to consumers as an OEM-correct replacement.

The PFL39811 uses the drilled-dimpled surface that Porsche specifies for this application - a combination of through-holes and blind dimples across the friction face that is engineered into the rotor at production rather than added aftermarket. This surface pattern is distinct from both smooth monobloc rotors (like the PFL39527 Macan S) and purely cross-drilled rotors; the dimpled sections provide surface disruption benefits without the complete through-penetration of full cross-drilling, while the drilled holes provide complete outgassing channels at their locations. The 315mm x 28mm specification is the base 2.7L Boxster/Cayman front brake size - higher-trim 981 variants (S, GTS, Spyder) use larger front rotors and different SHW part numbers.

Not compatible with Porsche Ceramic Composite Brakes (PCCB - yellow calipers). Left front position only; the right front is PFR39812 (OE# 98135140201). Replaces Porsche OE part 98135140101. Sold individually.
