Frequently Asked Questions
Q: Are ATS products same as CARBONETIC?
A: ACROSS has been authorized to distribute ATS products outside of Japan under their own brand name. "CARBONETIC" is a brand name for the products distributed by ACROSS. CARBONETIC products include ATS carbon products and selective ATS metal products as well as their own performance parts. Some of the Carbonetic products are assembled at ATS factory and others are assembled at ACROSS using the ATS parts or ACROSS parts.
PPI is the North America exclusive distributor of ATS products which are manufactured at the ATS with ATS parts under the ATS quality control.
Q: How does a clutch type LSD compare with a gear type LSD?
A: The gear type LSDs are popular choice for many manufacturers stock differentials. There is virtually no noise and the maintenance is very easy. A clutch type LSD, on the other hand, requires an LSD oil. However, when it comes down to performance, a clutch type LSD provides you with a much better response to your throttle and steering input. A clutch type LSD is the choice of professional drivers, which is the proof of performance. Also a gear type LSD behaves like a 1 way LSD and as such it is not preferred by many drifting drivers.
Q: Is ATS LSD streetable?
A: When a customer asks us this question, it usually means if our LSD is quiet and smooth. The answer is Yes. ATS carbon LSD (both old model, Spec II, and type street) does not have any chattering noise and the engagement is ultra smooth. In 2009, ATS released super silent LSD which is a metal LSD but does not have chattering or cranking noise. [It does chatter mildly during the break in period. However, after a 25min to 30min 8 figure break in, or after driving about 500miles, the chatter will disappear].
Q: My vehicle has too much push under and very difficult to turn. Is anything wrong with the LSD?
A: If an LSD has too much initial torque (break away torque), the vehicle becomes extremely difficult to turn. Please check the initial torque to see if it is within the factory spec. All ATS LSDs are checked for the initial torque when they are shipped out from the ATS factory. The initial torque should be less than 15 kg -m (108 lb-ft). However, if you purchase an LSD which is overhauled or assembled by a different company or shop, the initial torque might not be checked and the LSD could have a higher initial torque than the factory spec.
Q: Are ATS cluthes noiser than stock?
A:In general yes. Due to the very light weight flywheel, our clutches tend to pick up the engine vibration and gear noise more than the stock. The noise mostly comes from the gears contacting to other parts, which is caused by the inherent clearances existed when the engine and gears are assembled. This noise usually disappear when you disengage the clutch.
The other noise is typical for multi plate clutches. When the clutch is disengaged, the outer edges of the middle plate(s) [floating plate(s)] constantly make contact with the casing wall of the clutch and make noise. This second type of noise is currently limited to our twin and triple clutches and the single clutch does not have this noise.
