This StopFlex OEM-size kit keeps the factory caliper architecture and replaces the matched rotors, pads, hats, and floating hardware for the listed 390 mm, 402 mm, and 360 mm applications. The payoff is carbon-ceramic heat stability, lower rotating mass at each corner, reduced brake dust on open AMG wheels, and a fitment path tied to the exact R232 trim and rotor size.\u003c\/p\u003e\n\u003cul class=\"check\"\u003e\n\u003cli\u003e\u003cspan\u003eFront fitments are limited to 390 mm SL43, 390 mm SL55\/SL63 iron-brake cars, or 402 mm SL55\/SL63 carbon-ceramic cars; rear fitment is the listed 360 mm R232 AMG SL setup.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThe kit is built as an OEM-size replacement for the factory calipers, using carbon-ceramic rotors with matched pads, hats, and floating hardware instead of a caliper-conversion package.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eR232 SL55 and SL63 cars combine high curb weight, AWD traction, and repeated high-speed braking loads, making rotor heat capacity and front-end unsprung mass more important than on lighter roadsters.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/section\u003e\u003csection class=\"box red\"\u003e\u003ch2\u003eFitment Hard Lines\u003c\/h2\u003e\n\u003cdiv class=\"scroll\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth class=\"accent\"\u003eField\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVehicle\u003c\/td\u003e\n\u003ctd\u003eMercedes-AMG SL63 \/ SL55 \/ SL43 (R232)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel years\u003c\/td\u003e\n\u003ctd\u003e2022-2026+\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFront rotor reference\u003c\/td\u003e\n\u003ctd\u003eSL63\/SL55: 390mm, 402mm (CCB); SL43: 390mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRear rotor reference\u003c\/td\u003e\n\u003ctd\u003eSL63\/SL55\/SL43: 360mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePage type\u003c\/td\u003e\n\u003ctd\u003eOEM-size carbon ceramic replacement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum wheel size\u003c\/td\u003e\n\u003ctd\u003e20\" (for the 390 mm rotor)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\n\u003cdiv class=\"sf-emph\"\u003e\u003cp\u003eFor OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle.
