Competition Clutch 1990-1996 Nissan 300Z Stage 4 - 6 Pad Ceramic Clutch Kit
The Competition Clutch 6045-1620 is a Stage 4 Strip Series clutch kit for the Z32 Nissan 300ZX with the naturally aspirated VG30DE, and for RB-powered Skylines converted to a push-style release. It is aimed at cars that already make serious power: a 300ZX that has been turbocharged, supercharged or swapped and now spins the clutch under boost, or a drag car that needs the disc to hook hard. If your Z is mostly a weekend cruiser, read the section on alternatives before buying.
The pressure plate clamps the disc against the flywheel and the disc drives the five-speed input shaft. This kit uses a Competition Clutch performance pressure plate with a six-puck, sprung-hub disc faced with ceramic buttons. The ceramic material tolerates heat far better than organic facings, and the smaller contact area raises the clamping pressure on each puck. Competition Clutch rates the Stage 4 Strip Series at up to a 250 percent increase in torque capacity over stock. The trade-off is engagement: ceramic pucks grab quickly, so smooth low-speed driving takes more care.
Included, per the maker: performance pressure plate, six-pad ceramic sprung disc, throwout bearing and pilot bearing or bushing where applicable, and an alignment tool. A flywheel is not included. The 6045-0620 is the same kit with a solid-hub disc.
Make sure the problem really is slip and not a hydraulic or release fault. A soft pedal, a high engagement point or hard shifting with the engine running points to the master or slave cylinder or air in the line. Our slipping diagnosis guide covers a simple high-gear slip test, and shift flare vs. slip helps rule out other drivability issues. Also be honest about power: a Stage 4 puck disc is overkill on a stock engine.
Competition Clutch lists 6045-1620 for the 1990-1996 Nissan 300ZX and the 1989-2002 Nissan Skyline, with the note that the Skyline requires a push-style conversion. The 6045 part number is the non-turbo 300ZX; the factory twin-turbo 300ZX uses 6046-1620, a different kit. Engine and transmission swaps are common on these cars, so match the old disc diameter and spline, or send us your year, VIN and transmission details and we will confirm before you order.

For a street car with moderate power, the Stage 3 segmented ceramic kit engages more progressively, and the Stage 2 Steelback Brass Plus kit is the easiest to drive every day.

No. The 6045 kit is for the non-turbo 300ZX and push-style Skylines. The factory twin-turbo car uses 6046-1620.
Competition Clutch lists 1989-2002 Skyline fitment but notes the Skyline requires a push-style release conversion.
No. Resurface your flywheel or pair the kit with a lightweight steel flywheel made for the 300ZX.
It can be driven on the street, but engagement is quick and less forgiving in traffic. For a mostly street car, the Stage 2 or Stage 3 kits are easier to live with.
Competition Clutch recommends shifting as often as possible during the first 500 miles so the disc material embeds into the pressure plate and flywheel.
Both are Stage 4 six-puck ceramic kits. The -1620 has a sprung hub that softens driveline shock; the -0620 uses a solid hub.
