They are a direct replacement for the factory 345 x 30 mm discs, bolt on with the standard calipers and work with either factory or uprated pads.\u003c\/p\u003e\u003cp\u003eWhere most factory Audi discs use straight internal vanes, these have directional vanes that draw air in at the centre and push it outwards, so the disc sheds heat faster under repeated braking. They are cast in a heat-treated CM-250 alloy chosen for its resistance to heat cycling and warping, and the J-slotted faces clear pad debris and gases while spreading heat evenly. A Geomet coating protects against corrosion.\u003c\/p\u003e\u003cp\u003eTemperature-indicating paint on the disc edge shows how hot the brakes have been: green turns white at 478°C, orange turns yellow at 571°C and red turns white at 640°C. If the red mark turns white all round, the discs are running beyond their intended range. 034 aim these discs at daily driving, spirited road use, autocross and entry-level track days, and recommend their two-piece discs for more frequent or aggressive track use. As with any new discs, bed them in with the pads before hard use.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDirectionally vented for active cooling\u003c\/li\u003e\n\u003cli\u003eHeat-treated CM-250 alloy, resists warping\u003c\/li\u003e\n\u003cli\u003eJ-slotted friction faces\u003c\/li\u003e\n\u003cli\u003eTemperature-indicating paint marks (478°C \/ 571°C \/ 640°C)\u003c\/li\u003e\n\u003cli\u003eGeomet anti-corrosion coating\u003c\/li\u003e\n\u003cli\u003eDirect OE fit with standard calipers\u003c\/li\u003e\n\u003cli\u003eWorks with factory or performance pads\u003c\/li\u003e\n\u003cli\u003eSupplied as a front pair\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's in the box\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e034Motorsport 1-piece front brake disc pair\u003c\/li\u003e\u003c\/ul\u003e\u003ch6\u003eProduct Details\u003c\/h6\u003e\u003cdiv\u003e\n\u003cb\u003eBrand: \u003c\/b\u003e034 Motorsport\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003eManufacturer Part Number: \u003c\/b\u003e034-301-1025\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003eType: \u003c\/b\u003eFront Brake Disc Pair (1-Piece, Slotted, Vented)\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003eCountry of Origin: \u003c\/b\u003eUnited States\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003ePerformance Part: \u003c\/b\u003eYes\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003eDisc Size: \u003c\/b\u003e345 x 30 mm\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003ePosition: \u003c\/b\u003eFront axle\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003eMaterial: \u003c\/b\u003eHeat-treated CM-250 alloy\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003eFinish: \u003c\/b\u003eGeomet anti-corrosion coating\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003eReplaces OE Part Numbers: \u003c\/b\u003e8K0 615 301 M, 4G0 615 301 G, 4G0 615 301 AF\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003eShipping Weight: \u003c\/b\u003eapprox. 22.7 kg\u003c\/div\u003e\u003cdiv\u003e\n\u003cb\u003eUnit Quantity: \u003c\/b\u003e2 (pair)\u003c\/div\u003e\u003ch6\u003eVehicle Fitment\u003c\/h6\u003e\u003ctable style=\"width:100%; border-collapse:collapse; font-size:14px;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eManufacturer\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eEngine\/Platform\u003c\/th\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eS4 B8\/B8.5 saloon \u0026amp; Avant\u003c\/td\u003e\n\u003ctd\u003e3.0 TFSI\u003c\/td\u003e\n\u003ctd\u003e2008-2015\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eS5 B8\/B8.5 Coupe, Sportback \u0026amp; Cabriolet\u003c\/td\u003e\n\u003ctd\u003e3.0 TFSI\u003c\/td\u003e\n\u003ctd\u003e2009-2017\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eS5 B8 Coupe\u003c\/td\u003e\n\u003ctd\u003e4.2 FSI V8\u003c\/td\u003e\n\u003ctd\u003e2007-2012\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudi\u003c\/td\u003e\n\u003ctd\u003eQ5 8R\u003c\/td\u003e\n\u003ctd\u003e3.0 TFSI\u003c\/td\u003e\n\u003ctd\u003e2013-2017\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003eFor cars with the factory 345 x 30 mm steel front discs (OE 8K0 615 301 M, 4G0 615 301 G or AF).
