Competition Clutch VQ35HR/VQ37HR Stage 3 - Segmented Ceramic Clutch Kit
The Competition Clutch 6073-2600 is a Stage 3 street/strip kit for the later VQ engines: the VQ35HR in the 2007-2008 350Z and G35 and the VQ37HR in the 370Z and G37. It suits a forced-induction or heavily modified car where the factory clutch slips, and where the driver wants ceramic heat resistance but still drives on the street.
These cars use a single-disc clutch behind the VQ, released hydraulically. Competition Clutch rates its Stage 3 at up to a 150 percent increase in torque capacity over stock. The disc uses segmented ceramic facings that hold under heat far better than organic, and the kit pairs it with a performance pressure plate that Competition Clutch describes as giving quick, smooth engagement. Ceramic is chosen for holding power and durability under abuse; driven only in traffic it will feel sharper and less forgiving than an organic disc, and some chatter from a stop is normal.
Competition Clutch's specification table lists one disc, an alignment tool and a throwout bearing included, with no pilot bushing and no flywheel. Plan the flywheel separately.
A fourth-gear full-throttle pull from low RPM tells the story: if the tach jumps ahead of road speed, the clutch is slipping. Our slipping diagnosis guide and flare vs. slip explain what to watch. If the pedal is soft, stays down or the car grinds going into gear, check the slave cylinder and hydraulics first; our clutch won't disengage guide covers those checks.
Competition Clutch builds a full ladder for these cars, and the jump to Stage 3 is mainly about material. Organic and brass-plus discs feel close to stock but give up under sustained heat. Segmented ceramic tolerates repeated launches, drag passes and hot track laps, which is why it belongs on a car that is boosted or regularly abused. If the car is a mild bolt-on daily driver, the extra bite and faster wear on the flywheel face are a poor trade, and a milder kit is the better buy.
Competition Clutch lists 6073-2600 for the 2007-2011 Nissan 350Z/370Z and 2007-2013 Infiniti G35/G37. In practice that means the VQ35HR 350Z (2007-2008), the VQ35HR G35 and the VQ37HR 370Z and G37 manual cars. It does not fit the 2003-2006 VQ35DE 350Z; those cars use the 6072-2600 VQ35DE Stage 3. If you have a 2012-up 370Z, a swap or an aftermarket flywheel, send us the year and VIN and we will confirm before shipping.
Other choices for the same cars: the 6073 stock replacement kit for factory power, or the ACT NZ2-XTSS for an organic street feel.
