ATS Silent Carbon Clutch for 350Z w/ DE motor

ATS and Super Autobacs have been jointly working on the manufacturing of a new version of a high drivability carbon clutch. The challenge that ATS faced was to create a carbon clutch for 350Z which; 1) Can hold power at 500 horsepower - the Super Autobacs 350Z has a super charger with power well above 450 ps, 2) Does not have “hauling” or gear noise from the transmission when in a idle mode to a low range RPM , 3) Eliminates much of the shuddering, 4) The ATS Carbon Clutch maintains an excellent engagement characteristic.

Now the Silent Carbon Clutch has received approval from the Super Autobacs and professional driver Mr. Mitsuhiro Kinoshita, and it is ready for sales now. You will be able to see a Featured Article in REV Speed Magazine shortly.

In order to eliminate the unwanted harmonics and hauling noise, ATS decided to use a stock double mass flywheel. In addition, a soft type (Type S) internal discs is used to significantly reduce shuddering. At the moment, the silent carbon clutch for 350Z has only a twin model and with a 500 ps rated horse power at the wheel with a 1,100kg clamping force. (1,350kg clamping force is also available).

Expected release date - 1st week of May 2009. Place Your Orders to be the First on the Track with the ATS Silent Carbon Clutch.

Suggested retail price $3,035.00 including a new throw out bearing & shipping to your place

ATS twin / triple metal clutch for 350Z w/ HR motor

ATS has released a newly designed metal twin / triple clutch for Nissan 350Z with an HR motor. Similar to other ATS metal clutches, the newly designed performance clutch handles greater torque / horse power and can enhance your driving experience for your tuned 350Z .

This product is offered with two clamping rates—1,100kg and 1,350kg. The twin clutch can handle 450 hp with the 1,100kg clamping rate and 550 hp with the 1,350kg clamping rate clutch. The triple clutch is rated at 700 hp with a 1,100kg clamping rate and 850 hp with the 1,350kg clamping rate clutch.

As you may be aware of, there is a weak point in the CSC (Concentric Slave Cylinder) within the 350Z with an HR stock clutch. The CSC tends to be easily damaged when you increase the horse power of your 350Z. After multiple testing and R & D, ATS has concluded that the best way is to not utilize the CSC and use a withdrawal lever. This will have a similar activation system that is used for early model 350Z that have a DE motor. The ATS clutch kit comes with all the necessary parts for your installation.

An option that ATS offers is a NISMO big slave cylinder and a special mesh clutch line with excellent heat protection from the exhaust pipe.

The prices include the EMS (Express Air by the USPS) shipping from ATS Japan to your shop or to your customer. (This clutch does not fit 350Z early model with DE motor)

ATS Evolutionary metal LSD - Super Silent Limited Slip Differential

An inevitable drawback of a clutch type LSD has been the undesirable chattering noise. Even though the performance advantage of a clutch type LSD are well documented, many people have resorted to a "gear type" or "viscous type" LSD to avoid the noise during daily street driving. You no longer have to make that trade off!! The New ATS Super Silent LSD offers the best of the both worlds, the performance of clutch type LSD and the quietness of a gear type LSD.

Super Silent LSD will be available at the middle of December 2008 for 109 mm disc LSDs - LSD for 350Z, 240SX, Supra, RX7, RX8. Followed by 95 mm disc LSDs in February 2009.

Price - $90.00 additional over the currently available metal LSDs.
