This kit is a direct replacement that reuses your OEM calipers with new carbon-ceramic rotors, hats, pads, and floating hardware. Fitment is trim-specific: the TT RS uses 370mm front and 310mm rear rotors, while the TTS uses 340mm front and 310mm rear.

That's normal physics, not a defect, because the ceramic matrix and pad need a bit of energy before they reach working temperature. We tuned both the low-metallic resin-composite pad and the disc's ceramic coating specifically for cold pickup, so on the 8J the first-stop feel on a cold morning now comes very close to summer feel. Leave a little extra following distance on the very first stops until the front 370mm (TT RS) or 340mm (TTS) rotors take heat, then response is consistent.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eDo I need to run bigger wheels to clear these rotors?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eNo. Because this is a direct replacement that keeps the same factory rotor diameters — 370mm front on the TT RS, 340mm front on the TTS, 310mm rear on both — and reuses your OEM calipers, the package fits inside the same factory wheel envelope your car already runs.

During repeated hard stops, heat still soaks into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.\u003c\/p\u003e\u003c\/div\u003e\u003c\/section\u003e\u003csection class=\"cta\"\u003e\u003ch2\u003eGet Your Fitment Confirmed\u003c\/h2\u003e\n\u003cp\u003eShare your year, model, trim, wheel size, current rotor dimensions, and caliper type — every order is verified against your VIN-level configuration before it goes to production.\u003c\/p\u003e\n\u003cdiv class=\"cta-row\"\u003e\n\u003ca class=\"btn\" href=\"\/pages\/carbon-ceramic-brakes\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCarbon Ceramic Brakes: Buying \u0026amp; Fitment Guide\u003c\/a\u003e\u003ca class=\"btn ghost\" href=\"#contact_form_page\"\u003eConfirm Fitment\u003c\/a\u003e\n\u003c\/div\u003e\u003c\/section\u003e\u003csection class=\"box\"\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdiv class=\"faq\"\u003e\n\u003cdetails\u003e\u003csummary\u003eWill this kit bolt onto my exact C6 RS6, or is it a platform-wide fit?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eIt is engineered specifically for your confirmed C6 RS6 trim, not assumed from the shared chassis. The RS6's V10 front knuckles, hub geometry, and wheel ET differ from lesser C6 A6\/S6 models, so we cut brackets, rotor-hat offsets, and caliper mounting to your car. We never sell this as a universal platform bolt-on.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat wheels do I need to clear the 420mm front rotors?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eThe 420mm front rotor sets a hard minimum of 21-inch wheels.

Leave a little extra following distance on the coldest first stops.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eDoes the rear caliper keep my factory parking brake?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eThe TTSPORT EP4 rear caliper carries a dedicated EPB actuator piston alongside its 4 hydraulic pistons on the 380mm rotor.
