That keeps the pad face clean as it wears, so bite stays consistent through repeated hard stops rather than tailing off as the brakes heat up. Slotted discs are a common upgrade on cars that see spirited road driving or occasional track days, and they pair with the pad compound you already prefer.\u003c\/p\u003e\u003ch3\u003eInstallation\u003c\/h3\u003e\u003cp\u003eThese discs are built as a replacement for the factory units on the listed application, so the job is a standard rotor change: pull the caliper and carrier, swap the disc, and bed the brakes in before hard use. Inspect pads, hardware and hoses while the corner is apart and replace anything worn at the same time.\u003c\/p\u003e\u003cp\u003eFree shipping on orders over $75. 30-day returns.\u003c\/p\u003e","brand":"GiroDisc","offers":[{"title":"Default Title","offer_id":58443870830895,"sku":null,"price":1350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0992\/1822\/7503\/files\/11c9a432f0166a8cbbc66c916e1e6c15_e3969b9e-3832-4646-b5e6-6e12dc0a5db2.jpg?v=1788910875","url":"https:\/\/corebrakeparts.com\/products\/girodisc-a1-122-slotted-front-rotor-set-350mm-porsche-911-carrera-s-4s-and-gts-991-1","provider":"CoreBrakeParts.com","version":"1.0","type":"link"}
