GiroDisc 355x35mm 10 Pin Holes 52mm Annulus Slotted Rings for Porsche 997 GT3 GT3 RS GT2 2007-2010
Girodisc slotted rotor rings measure 355mm diameter by 35mm thick designed as direct front replacements for Porsche 997 GT3 GT3 RS and GT2 models from 2007 to 2010. These high-carbon rings bolt to Girodisc hats using 10 pins for two-piece rotor assembly that cuts unsprung weight by 7 pounds per corner versus OEM. Slotted surfaces clear gases and debris for consistent stopping power under track or street conditions.
