Differential
The following changes have been made to the Super AYC differential.
• Reduced weight: The weight of the differential has been reduced by building the clutch case from aluminium, rather than
steel, and partially revising the thickness of the clutch discs.
• Improved strength and durability: Strength and durability have been raised by adopting special highstrength steel for the
hypoid gears (pinion gear and drive gear), instead of the cast steel used previously.
• Improved control when ABS is operating: Revisions to the communications with the ABSECU and the control procedure
during ABS operation, as well as active ACD/AYC control in high friction road surfaces, such as circuits, have led to
increased steerability and stability.
