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.

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
