Diaphragm Clutch System

Diaphragm Clutch System is a clutch system manufacturer in Grand Theft Auto Online.

Description
Diaphragm Clutch System appears on racing liveries in Grand Theft Auto Online as a sponsor. Diaphragms logo appears to represent the circular discs and plates in a clutch system.

Diaphragm might be based on Exedy Racing Clutch, as they share similar logos with circular clutch covers and a tagline under the main name header.

Trivia

 * The name Diaphragm could likely refer to Diaphragm (birth control), being another instance of Rockstar's crude humour.
