Compound Overview

GP10 Street Pads for 1001 Shape – GP10-1001.15
Designed for performance-minded drivers, GP10 semi-metallic pads balance daily drivability with the ability to handle occasional track sessions. They offer reduced noise and dust compared to full race pads while maintaining responsive pedal feel and consistent stopping power when speeds increase. For frequent or extended track use, Girodisc recommends moving to a dedicated race compound for improved heat capacity.

GP35 Race Pads for 1001 Shape – GP35-1001.15
GP35 is the all-around race compound that blends sprint-level bite with endurance-style durability. It beds quickly and is designed to work cleanly with both street-car ABS and motorsport-grade ABS. A smooth, linear torque curve delivers excellent modulation and release under trail braking, making GP35 a popular choice for advanced HPDE drivers and cars competing in a wide range of racing environments. Compatible only with iron rotors.

GP40 Sprint Race Pads for 1001 Shape – GP40-1001.15
GP40 offers strong race-ready bite without excessive rotor wear, sitting between a pure sprint and endurance formulation. It maintains pedal feel and heat stability during intense lapping sessions and has been proven in demanding race conditions. GP40 is ideal for drivers seeking aggressive braking performance with controlled wear characteristics.

Girodisc GP-Series 1001 Pad FAQs

Is GP10 suitable for daily driving? Yes. GP10 is designed for street use with reduced noise and dust while allowing occasional track sessions without sacrificing pedal feel.

When should I choose GP35? GP35 is the right choice for frequent HPDE or club racing where a single compound needs to handle a wide range of conditions with strong bite and excellent modulation.

Who is GP40 intended for? GP40 is ideal for aggressive track drivers and sprint-race applications requiring higher friction and strong initial bite while keeping rotor wear manageable.

Are these pads compatible with carbon-ceramic rotors? No. All GP10, GP35, and GP40 1001 pads are designed exclusively for iron rotors and should not be used with carbon-ceramic systems.

Do these pads work with factory ABS systems? Yes. All compounds in the 1001 series are formulated to function properly with OEM ABS and stability-control systems when correctly bedded.

Upgrade your Porsche with Girodisc GP-Series 1001 pads and choose the compound that matches how you drive—whether that means quiet street comfort, versatile all-around performance, or sprint-race capability.
