ACT XT/Race Sprung 6 Pad Clutch Kit, 1990-1998 Nissan Silvia & Bluebird SSS Attessa [JDM] | NS1-XTG6

The NS1-XTG6 kit pairs an ACT Xtreme pressure plate with a 6-pad, spring-centered race disc for the JDM Nissan Silvia and Bluebird SSS Attessa (2.0L turbo). The Xtreme pressure plate uses ACT's exclusive diaphragm design and four-stage heat treating to increase clamp load for the most demanding drivers. The 6-pad race disc uses spring-center construction to properly damp torsional vibration and resist failure under harsh conditions, with wraparound spring windows and thicker retainer stampings for added strength; engagement is firmer than a street disc but shifting is faster, and it is recommended for larger clutch sizes.

Frequently Asked Questions

Are ACT clutch kits balanced?

Yes. Every ACT clutch assembly is computer spin-balanced to within .25 oz-in, tighter than the .50 oz-in typical of stock production clutches, for smoother operation across the RPM range.

Will this clutch increase pedal effort?

ACT pressure plates are engineered for higher torque capacity, so pedal effort typically increases 15-40% with a Heavy Duty pressure plate and 50-80% with an Xtreme pressure plate compared to stock, depending on the application.

Does this clutch need a break-in period?

Organic street discs should be broken in for 300-500 miles of mild, stop-and-go driving before spirited use. Race discs generally only need a few hard slips to lap the surfaces before normal use. Avoid overheating the clutch during break-in, as this can glaze the friction surfaces.

Is this clutch kit repairable or rebuildable?

In some cases a rebuild or repair may be possible after inspection; contact ACT's technical department for guidance, and use a qualified clutch specialist due to the kit's specialized components.
