With a 7.8 mm lining thickness, it offers the largest wear reserve in the RCS range, making it suitable for endurance racing, rally, and applications with consistently high loads.\u003c\/p\u003e \u003cp\u003eCompared with the 2.6 mm, 3.4 mm, and 5.2 mm variants, the 7.8 mm disc provides significantly more friction material. This increases heat capacity, reduces temperature spikes, and lowers the risk of fading or warping. The large wear reserve also extends service intervals under extreme conditions.\u003c\/p\u003e \u003cp\u003eThe sintered pads ensure stable, consistent friction behavior throughout the service life. Even during repeated full-load runs, the bite point remains precise, launch behavior predictable, and Torque transfer reliable. While thinner discs provide lower rotational inertia and quicker response, the 7.8 mm disc offers greater robustness and temperature stability for consistent performance over long distances.\u003c\/p\u003e \u003ch3\u003eTechnology:\u003c\/h3\u003e \u003cp\u003eCompared with organic friction linings, the sintered metallic friction material is more temperature-resistant, stable at high rpm, and insensitive to dirt and oil. It delivers an aggressive response with hard launch characteristics and rapid engagement during race starts, while supporting significantly higher Torque capacity for high-power race cars.\u003c\/p\u003e \u003cp\u003eAs a core component of the modular SACHS RCS 140 clutch system, the disc is matched to motorsport applications ranging from rally and autocross to circuit racing.\u003c\/p\u003e \u003ch3\u003eSACHS RCS Hub:\u003c\/h3\u003e \u003cp\u003eSACHS RCS 140 7.8 racing clutch discs are available with different hub profiles matched to the respective gearbox input shaft. This ensures fit accuracy, reliable power transmission, and durability in demanding motorsport use.\u003c\/p\u003e \u003cp\u003eHubs are also available in different Length options: short, medium, and long. This supports optimal packaging within the available space and correct actuation. The modular ZF Motorsport RCS 140 system enables a tailored racing clutch with high performance, thermal robustness, and service life.\u003c\/p\u003e \u003ch3\u003eSpecifications:\u003c\/h3\u003e \u003cul\u003e\n\u003cli\u003eClutch disc RCS 140-S7.8-M-980\u003c\/li\u003e \u003cli\u003eFriction material: Sinterpad, 7.8 mm\u003c\/li\u003e \u003cli\u003eSpline profile: (980) - 32 \/ 64 - 26 - 37,5º\u003c\/li\u003e \u003cli\u003eHub length: medium\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SACHS PERFORMANCE","offers":[{"title":"Default Title","offer_id":43136859406516,"sku":"881864002197","price":240.38,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/2605\/3812\/files\/image-coming-soon_d615d496-5e6f-46dc-ac11-b311e90955eb.png?v=1788518184","url":"https:\/\/atomic-shop.eu\/products\/sachs-performance-881864002197-clutch-disc-rcs-140-s7-8","provider":"ATOMIC-SHOP Performance Parts \u0026 Motorsport Equipment - EU","version":"1.0","type":"link"}
