With the advanced case design for the superb oil circulation, the ATS Type DD LSDs can handle the tough endurance race (w/ slick tires) without any deteriorated performance.

The new LSD case has enough room for 4 to 6 coned shape springs, which enables to make a high initial torque carbon LSD and carbon hybrid LSD.

The outer edge grooves of the new LSD case release the oil so effectively that the sludge which frequently generated on the break-in process is also discharged with the oil. The eliminated sludge no longer causes the wear of carbon chips and clutch discs, resulting in a significant slowdown on decline of the initial torque.
