A Type-R LSD the Matsui Spec      Model # HFC8791T-SPL

Equipped to Mr. Matsui’s Civic FD, the ATS Type-R LSD made a spectacular debut winning the first round of the Civic Inter Series at Okayama International Race Track.

The LSD uses the S Type (Silent type) plates which are used for our Super Silent LSD. The cam ring is a one way with a 70 degree angle with the initial torque set lower than a standard LSDs.

● The plates have a throw-through oil design which was born from extensive research and development by ATS engineers.
● The throw-through oil design maintains the oil film on the surface of the plates minimizing the fluctuation of oil temperature and friction coefficient.
● The surface asperities of the plate are minimized to the utmost limit to eliminate the time lag from free position to the locking position
● A One-way cam assures a minimum dragging effect on deceleration, which makes it easier to stay in the targeted racing line.
● Abrupt locking of the differential is eliminated by the excellent combination of plate properties, initial torque, and the cam angle. Thus a driver can try daring throttle control maneuvers.
