SACHS RCS 184 S2.6 Racing Clutch Disc R88186499D086
Lightweight sintered metal clutch disc with 2.6 mm lining thickness for SACHS RCS 184 racing clutches
The SACHS RCS 184 S2.6 sintered metal clutch disc R88186499D086 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 just 2.6 mm lining thickness and is designed for fast response, direct power transmission and a low moment of inertia in motorsport.
This version is aimed at applications where short, intensive load windows, fast rpm changes and precise engagement are the main priorities. Compared with S5.2 and S7.8 versions, the S2.6 offers less friction material reserve, but reacts particularly spontaneously and reduces the rotating mass in the clutch pack.
The 184 mm format provides a practical middle ground between the very compact RCS 140 and the large-format RCS 200. Compared with smaller 140 mm versions, the RCS 184 provides more friction surface and thermal reserve, while remaining more compact and more responsive than a 200 mm system.
The part number R88186499D086 identifies the specifically selected version with the matching hub profile for the respective gearbox input shaft. The clutch disc is intended for use within SACHS RCS 184 clutch configurations approved by ZF Race Engineering.

Technology
Sintered metal 2.6 mm
The SACHS RCS 184 S2.6 sintered metal clutch disc R88186499D086 is designed for fast response, direct power transmission and a low moment of inertia. The sintered friction lining supports very direct engagement behaviour and clear feedback in motorsport use.
The 2.6 mm lining thickness reduces the rotating mass in the clutch pack and promotes fast rpm changes. Compared with S5.2 and S7.8 versions, this variant places greater emphasis on agility; wear reserve and thermal capacity are deliberately designed for short, intensive application profiles.
The 184 mm diameter creates a practical combination of compact design, fast response and sufficient friction surface for high loads. This makes the S2.6 version suitable for vehicles where low inertia and durable power transmission are required together.
Hub profile
The hub profile of the SACHS RCS 184 S2.6 clutch disc R88186499D086 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.
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 factory-approved hub length combinations 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 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 R88186499D086 identifies the specific version of this SACHS RCS 184 S2.6 sintered metal 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.
