Package includes :

Z1 Performance Clutch Kit
Z1 Lightweight Flywheel
Z1 Stainless Steel Clutch Line
AVAILABLE CLUTCH TYPES

Two different clutch types are available in this package, offering flexibility in power support and driving style. Both clutches utilize pressure plates with a low spring load. 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".

Z1 Performance Street Clutch - This package utilizes a pressure plate with a moderate clamping load, supporting more power without the stiff pedal and increased effort that comes with most performance clutches. With a standard disc, this clutch is perfect for naturally aspirated and boosted street cars making around 500-550whp. With a 6-puck disc, expect this clutch to support in the realm of 600whp.

Z1 Road Race Clutch - This package utilizes a pressure plate with a high clamping load and is capable of supporting substantially higher levels of power over OE-type clutches. We generally recommend this clutch for users that prefer a more aggressive engagement or power capacity. This clutch works great for road course track cars and can support power levels beyond 600whp with the standard disc. When used with a 6-puck disc, we have confidently used this clutch up to and beyond 700whp.

For drag racers, we recommend our Drag Pack Clutch Kit, complete with nodular iron flywheel and high clamp pressure plate.

Three different disc options are available. Both full-face discs have reverse shear protection and employ Marcel springs to improve performance on the street.

Z1 Sprung Hub Full Face (Standard) - This disc is a great choice for street-driven cars. The sprung hub allows for easy engagement with minimal noise and also works well for stock-like driveability in moderate to high horsepower applications. Disc weight: 3.5lbs
Z1 Unsprung Full Face - This disc is a great choice for street and track cars that want the lightest disc. The unsprung hub allows for more aggressive engagement in moderate to high horsepower applications. These clutches have a more 'harsh' engagement than a standard sprung hub clutch, so some adjustment to your driving style may be necessary on street-driven applications. Disc weight: 2.8lbs
Z1 Ceramic 6-Puck - This disc is best suited for high-horsepower cars, and has the most aggressive engagement of the three options. Engagement is quick due to it's 6-puck design, so some adjustment to driving style will be needed to compensate for its aggressive engagement, however, this disc can still be used on street-driven cars. Disc weight: 4.0lbs
