Z1 is fully operational. No disruptions to our huge inventory selection & quick shipping.
This package fits '03 - '06 350Zs and G35s and is capable of holding the power of all naturally aspirated and, depending on the options you choose, most forced induction applications up to 500ft-lb tq. At the same time reducing the total weight of the clutch and flywheel assembly to 29.75 lbs vs 46.6 lbs stock.
Z1 Motorsports Mild Performance Clutch - This kit utilizes a pressure plate built to OEM Spec clamping forces. This pressure plate along with any of the discs available in this kit allows the handling of more power without a change in pedal feel. We find this clutch option typically best suited for applications up to approximatley 350lb-ft.
Z1 Motorsports Performance Street Clutch - This kit utilizes a high clamping force pressure plate with a low spring load. High clamping force refers to the increased amount of pressure that is applied to the clutch disc. A low spring load eases lateral force on the main thrust bearings in your engine, which is especially important during "dry" start-up, lessening the likelihood of "crank walk". This pressure plate along with any of the discs available in this kit will handle substantially more power with a slightly "heavier" pedal feel. We find this clutch option typically best suited for applications up to approximatley 500lb-ft..
Z1 Performance Light Weight - This Solid 4140 Forged Steel flywheel weighs 14.2 lbs. The light weight increases throttle response and helps reduce turbo lag for those boosted.
Z1 Performance Mid Weight - This Solid 4140 Forged Steel flywheel weighs 21 lbs. The mid weight helps maintain engine RPM between shifts.
Exedy Lightweight - This Solid 4140 Forged Steel flywheel weighs 19.05 lbs. This flywheel is lighter than stock but still heavy enough to help reduce excess transmission noise (chatter).
Optional Friction Disc
Standard Full Face - This is an OEM Type disc with a sprung hub and upgraded full friction surface to aid in driveability and engagement but also hold all of your NA Upgrades.
Sprung Hub 6 Puck - This is a sprung hub disc made up of ceramic "pucks" that provide a more aggressive engagement and hold a lot more power than the organic full face material.
Unsprung Full Face - This is a lightweight solid hub disc with an upgraded full friction surface to allow a more direct engagement without the aggressiveness of ceramic pucks.
This Clutch and Flywheel combo does not fit 07+ VQ35HR (Dual Throttle Body) Engines. For later models, please choose our VQ35HR Package.
