SACHS RCS 184 O7.8 Racing Clutch Disc R88186499O088
Organic clutch disc with 7.8 mm lining thickness for SACHS RCS 184 racing clutches
The SACHS RCS 184 O7.8 organic clutch disc R88186499O088 from ZF Motorsport is a high-quality driven plate for modular SACHS RCS 184 multi-plate racing clutches. It combines the 184 mm diameter with 7.8 mm lining thickness and an organic friction lining for easily controllable engagement, controlled power transmission and drivetrain-friendly driving behaviour.
This version is aimed at applications where drivability, modulation and reproducible pedal feel are more important than the aggressive response of a sintered metal or Sinter Pad clutch disc. The organic friction lining engages more smoothly and predictably and can reduce load peaks in the drivetrain.
The 184 mm format offers a practical middle ground between the very compact RCS 140 and the large-format RCS 200. Compared with RCS 140, the RCS 184 provides more friction surface, yet remains more compact and responsive than a 200 mm version. This makes this organic clutch disc especially suitable for trackday, clubsport, slalom, youngtimer and historic applications.
The part number R88186499O088 identifies the specifically selected version with the matching hub profile for the respective gearbox input shaft. The clutch disc is intended for use within approved SACHS RCS 184 clutch configurations.

Technology
Organic 7.8 mm
The SACHS RCS 184 O7.8 organic clutch disc R88186499O088 is designed for controlled power transmission, good modulation and harmonious engagement behaviour. The organic friction lining works more smoothly than sintered metal and is suitable for applications where drivability and material protection are the main priorities.
The 7.8 mm lining thickness offers a solid material reserve for trackday, clubsport, slalom and historic applications. Compared with Sinter Pad clutch discs, the organic version engages less aggressively and enables finer modulation when pulling away, manoeuvring and at low speeds.
Thanks to the 184 mm diameter, the clutch system remains more compact and responsive than a large-format 200 mm version. At the same time, the RCS 184 provides more friction surface than smaller 140 mm systems, offering a balanced basis for driver-friendly racing clutches.
Hub profile
The hub profile of the SACHS RCS 184 O7.8 organic clutch disc R88186499O088 is matched to the respective gearbox input shaft. This creates an accurate connection between clutch disc and gearbox, which is essential for clean power transmission and high operating reliability in motorsport and performance use.
When replacing a worn clutch disc, the existing hub length version of the SACHS RCS 184 clutch must be retained exactly. For new builds, conversions or individual assembly of an RCS 184 clutch pack, only the hub length combinations approved by ZF Race Engineering for the respective clutch configuration may be used.
Before installation, the hub profile should be checked against the existing gearbox input shaft as well as the clutch cover, intermediate plates, pressure plate and approved RCS 184 configuration.
SACHS RCS 184 system
As part of the modular SACHS RCS 184 clutch system, the organic clutch disc is combined with approved pressure plates, intermediate plates and clutch covers. The decisive factors are the number of discs, lining thickness, installation height and the correct setup of the entire clutch pack.
The part number R88186499O088 identifies the specific version of this SACHS RCS 184 O7.8 organic clutch disc. For safe function, clutch disc, friction partners, clutch cover, pressure plate, intermediate plates and installation dimensions must be considered as a complete system.
