These shims help manage heat transfer from the brake pads to the caliper pistons, making them a useful addition for autocross, track days, and other demanding driving conditions.\u003c\/p\u003e\n\u003cp\u003eRepeated hard braking generates substantial heat that can transfer into the calipers and brake fluid, potentially contributing to brake fade and reduced braking consistency. By placing a thermal barrier between the back of the brake pad and the caliper piston, these shims help slow heat transfer into the caliper and fluid.\u003c\/p\u003e\n\u003cp\u003eManufactured from 6AL-4V Grade 5 titanium, each shim measures 1.0mm thick. Titanium's relatively low thermal conductivity compared with steel makes it well suited for this application, helping manage caliper temperatures during repeated braking without replacing the complete braking system.\u003c\/p\u003e\n\u003cp\u003eEach kit includes four shims designed for compatible FMSI D1365 brake pads. This provides a straightforward way to support brake thermal management during extended track sessions and may help preserve brake pad service life under demanding conditions.\u003c\/p\u003e\n\u003cp\u003eFactionFab notes that these shims may be permitted in many SCCA and NASA competition classes, but eligibility depends on the vehicle and class regulations. Check the current rules and verify your exact pad shape and caliper configuration before ordering.\u003c\/p\u003e","brand":"FactionFab","offers":[{"title":"Default Title","offer_id":49297721360635,"sku":"FFA1.10316.1","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0717\/5893\/files\/FFA1.10316.1WBGx1600-4.jpg?v=1789133729","url":"https:\/\/www.pandamotorworks.com\/products\/factionfab-titanium-front-brake-shim-set-2018-2021-sti-2024-wrx-ts-tr","provider":"Panda Motorworks","version":"1.0","type":"link"}
