Spec 03-06 350z Mini Twin P- Trim Clutch Kit
Once a 2003-2006 Nissan 350Z or Infiniti G35 is making serious boost, a single disc clutch turns into the weak link: it flares on the 2-3 shift, slips on a third gear pull, or overheats after a few track laps. SPEC part number SN35PT is a P-Trim twin disc assembly for the VQ35DE cars, and SPEC rates it at 1,156 ft-lb of torque, far beyond what a naturally aspirated VQ35DE produces.
A twin disc clutch puts two friction discs and a floater plate between the flywheel and pressure plate. Doubling the friction surfaces raises torque capacity without a larger diameter or a crushing pedal, which is why this style is used on high horsepower street, drag and road race cars. SPEC describes its multi-disc assemblies as clutch and flywheel assemblies, built for cars where a single disc cannot hold the power.
Our listing title calls this kit a Mini Twin, while SPEC's own product page files SN35PT under its Super Twin family in the P-Trim category and simply describes it as a Nissan multidisc. Either way, the numbers on SPEC's page are what matter: 1,156 ft-lb torque rating and a 34 lb assembly. For comparison, SPEC rates the Organic Trim SN35SST-O at 847 ft-lb, so the P-Trim is the choice when the car is built for big power and sees track or strip time, not just commuting. If you only need more holding power on a mild build, the SPEC SN353 Stage 3 single disc is the simpler option.
Do a controlled slip check in third gear from about 2,500 rpm at full throttle. If the tach rises without the car pulling with it, the clutch is slipping. If the problem is grinding into gear, a soft pedal or poor release, bleed the hydraulic system and inspect the master and slave cylinders before spending money on a clutch. Our slipping diagnosis guide lays out the order of checks, and the manual repair cost guide helps budget the labor.
SPEC lists SN35PT for the Nissan 350Z from 2003 through 2006 and the Infiniti G35 from 2003 through 2006, manual transmission cars with the VQ35DE. The early cars used the FS6R31A six-speed, and Nissan introduced the updated CD009 on 2005 Rev-up models, so tell us which gearbox you have. The 2007 and later VQ35HR cars are not covered by this part number. Send your year and VIN and we will confirm before it ships. Automatic cars do not use a clutch; for those, see our RE5R05A service guide.
An aggressive twin disc is louder than a stock clutch at idle and engages quicker. Follow SPEC's break-in guidance before launching the car or turning the boost back up.

SPEC lists it for 2003-2006 350Z and 2003-2006 G35 manual cars with the VQ35DE. The 2007 and later VQ35HR cars need a different part. Send your year and VIN to confirm a G35.
SPEC rates the SN35PT at 1,156 ft-lb of torque, well above the 847 ft-lb Organic Trim version.
Our listing title says Mini Twin, but SPEC's product page places SN35PT in its Super Twin P-Trim category and calls it a Nissan multidisc. The part number, fitment and torque rating are the same either way.
It is built for high power cars that see track or strip use. Expect quicker engagement and more noise than stock. For a mostly street car, the Organic Trim SN35SST-O is smoother.
Replace the pilot bearing, check the release bearing and fork, and flush and bleed the clutch hydraulics with fresh fluid.
