SACHS PERFORMANCE R88186499Q105 Clutch Disc RCS 115-S2.6

Description SACHS PERFORMANCE R88186499Q105 Clutch Disc RCS 115-S2.6

The SACHS RCS 115 2.6 sintered-metal clutch disc from ZF Motorsport is a no-compromise lightweight racing solution. With a diameter of just 115 mm—the smallest RCS format and closest in concept to modern Formula 1 clutches—it delivers ultra-low rotating mass, sharp response, and maximum packaging freedom in tight single-seater monocoques.

The sintered Friction material is directly sintered onto the carrier plate, creating a very stiff friction pair with a precise bite point, aggressive launch characteristics, and fast engagement. The 2.6 mm lining minimizes inertia, supports rapid engine spin-up, and eases synchronizer load during shifts.

The high-temperature sintered material remains stable under extreme friction energy and transmits Torque reliably, making it ideal for short, intense duty cycles.

Technology

The dedicated sintered Friction material delivers an immediate bite with hard launches and snap engagement off the line while handling significantly higher Torque than organic clutch discs.

As a core element of the modular SACHS RCS 115 clutch system, it is purpose-built for professional motorsport, including formula cars, circuit racing, and prototypes.

SACHS RCS hub

SACHS RCS 115 2.6 clutch discs are available with precisely matched hub profiles for the specific gearbox input shaft, ensuring a precise fit, reliable Torque transfer, and durability in hard racing use.

RCS 115 clutch discs are supplied exclusively with a short hub. The Lightweight design minimizes inertia, reduces total clutch pack Length, and supports direct, precise actuation.
